The Climate Is Changing and So Must We—Fiona Hill’s vision

At the Glasgow Climate Conference this past week, world leaders signed an agreement to cut back on the use of coal and other fossil fuels. Mining, manufacturing and even farming have been revolutionized over the past fifty years and more mines and factories will close as a result of these international agreements. Jobs that used to be central to every modern economy are disappearing. We know that jobs must change, the question is, how can we help people to change so that they can find security in the new economy.

Few people have been able to observe the effects of changing economies on the lives of everyday people as closely as Fiona Hill, the author of There Is Nothing for You Here: Finding Opportunity in the Twenty-First Century.

Fiona Hill

Hill was born in 1965 and grew up in County Durham in Northern England in a community that had been devastated by the closure of coal mines during the decades following the second World War. Although Hill’s family had been miners for generations, both her father and mother were hospital workers during most of the years when they were raising their children. The title of Hill’s book, There Is Nothing for You Here, comes from the advice given to Fiona and her sister as their parents realized that education was the key to moving ahead in the modern world.

During the 1980s when Hill was growing up, education was easier to obtain in England than in the United States or in many other countries. Government support enabled children to move from local council (public) schools to university. Publicly funded stipends meant that poverty was not an insurmountable obstacle for many students, but Hill clearly shows the obstacles that stood in the way of young people who wanted to move ahead. Expenses that were ignored by the government, such as the insufficient supply of books in local libraries and schools, the cost of transportation to cities where scholarship tests were available, and the prejudice shown against students who did not fit into the middle-class mold of most university applicants made entry into the university system very difficult. Hill describes her interview for entry into Oxford as one of the worst experiences of her life.

Despite all the difficulties of moving ahead, Hill managed to acquire a university education at St. Andrew’s where she found mentors who helped her find opportunities for further study. Later, she was able to attend Harvard and earn a PhD. She also spent time in Russia where she could observe the results of the post-cold war economic turmoil on the lives of Russian students. This varied background has given her a wide range of experience about the ways in which different countries are meeting the challenges brought by changing economies.

When Hill moved to the United States, eventually becoming an American citizen, and marrying an American, she observed many similarities between the way working class families coped with change in the two countries. The American Midwest, where her husband grew up, faced the loss of manufacturing jobs just as County Durham had. Towns in the Rust Belt of the Midwest were experiencing the same difficult adjustments as towns in the UK, except that class differences in America are complicated by racial differences which also affect people’s education and job training.

There Is Nothing for You Here is a dense book, filled with the stories of various individuals who are adjusting to a new world. Hill became an expert in National Security and relations with Russia and worked in the White House during the early years of the Trump Administration. She became well known after she gave testimony during Trump’s First Impeachment Trial where the focus was on relations between the United States and Russia. Now she has given us a broader picture of growing up in a changing world. Her book raises questions about how countries can help individuals find a path to changing their lives.

While leaders sign proclamations and declare goals, Fiona Hill reminds us that it is individuals who will bear the brunt of fitting into the new world. There Is Nothing for You Here points the way to some of the changes that are needed.     

Elections Come and Go but the Climate Keeps Changing

American news has been dominated this week by stories of President Trump’s illness and hospitalization. But it is important to remember that even a hard-fought presidential campaign may not be as important in the long run as the dramatic events happening in the natural world. The bizarre weather generated by changes in climate will affect us long after our next president has been chosen. This year’s hurricane season on the Southern coast has sent one hurricane after another up through the Gulf of Mexico. Weather watchers have even run out of names for new hurricanes, although the season is not half over. 

Wildfires in California and Oregon have filled the skies with smoke over large parts of several states. On September 9, San Francisco and much of the Bay Area suffered through a day of darkness. Skies were bright reddish orange soon after sunrise and faded to a deep yellow after several hours. Pedestrians moved through dark street with careful steps and headlights and streetlights were on for most of the day. Normal daylight did not arrive until late in the afternoon. 

Although during the week after September 9 the darkness let up, air continued to be smokey and unhealthy. Gradually as winds came in from the Pacific, smoke drifted to the Eastern states. It was a grim reminder of how weather affects everyone and how much a change in the weather can change our lives. At least now scientists and others are beginning to understand the causes and results of climate change. The tragedy is that some people refuse to acknowledge that information and prefer to drag us back into ignorance. 

Throughout history, some of the most dramatic changes have been brought by events most people knew nothing about. In 1815 a volcanic eruption brought changes to climate around the world—and the most frightening part of the events was that no one knew what had caused them. 

For three years weather was disrupted throughout the world—China had floods, Europe had freezing temperatures in June and July, and in America crops the New England States were hit by heavy frosts and snow during May and June. All of these disruptions were caused by a huge volcanic eruption of Mount Tambora on an island which is now part of Indonesia. The explosion sent streams of ash into the air where it lingered and caused temperatures to drop around the globe. Europe suffered crop losses that caused overwhelming damage in Ireland, Wales, and Germany. Prices rose sharply leaving hungry peasants suffering. Demonstrations at grain markets and bakeries, followed by riots, arson, and looting, took place in many European cities. It was the worst famine of the 19th century. 

Observers were baffled by what could have caused the extreme changes in weather, and political leaders struggled to explain events. Some people blamed it on sunspots. Many others turned to religion for an explanation. In upstate New York, Joseph Smith announced he had discovered new revelations from God that led eventually to Smith’s founding of the Mormon church. No satisfactory explanation was found for the dramatic climate changes of 1815 to 1817. The volcanic ash gradually disappeared, floating to the earth in small droplets. Temperatures returned to a more normal pattern.  

For the complete story of the upheavals caused by the Tambora eruption, you can read The Year without Summer; 1816 and the Volcano that Darkened the World and Changed History  by Klingaman, William K. and Klingaman, Nicolas P.  It is not a book that is easy to forget. 

More than two centuries have passed since Tambora caused these dramatic changes in climate. But once again we are in the midst of climate changes that are affecting the lives of many people around the world. Temperatures are rising throughout the world making many areas of the world unlivable. But now scientists have collected enough data to know what we should be doing. It is time for all of us to acknowledge the danger and to work toward solutions instead of ignoring the challenge. The Union of Concerned Scientists has some important suggestions for all of us.    

Cooperating across Borders to Save the World

The news has been so filled with disaster stories these past weeks that it’s hard to decide which of them to worry about first. But probably the one that tells us about the greatest threat to the world is the story of disastrous climate change. A report from the Intergovernmental Panel on Climate Change warns us about how changing weather conditions may affect the food supplies of millions of people. Scientists and governments will have to work together to help people make changes that may save many of us from starvation.

Sometimes we forget that science has always been international. The search for knowledge about the natural world and the forces that control it has ignored national boundaries and spread to governments and people worldwide. Some of the best examples of scientific cooperation came about a couple of centuries ago when America was seen, from the European viewpoint, as a new country. Botanists were among the early explorers who discovered and described the plants and animals that Native Americans had long known about but were unknown in other counties. Last year, I wrote a post about David Hosack, an early botanist who shared his knowledge and his plants with scientists across Europe.

Botany was recognized as an important science because at that time most medical treatments depended on using medicines derived from plants. Fortunately, it was also a science that did not require expensive equipment or training. One of the earliest American botanists was a woman who lived and died years before the United States was formed.

Jane Colden

Jane Colden was born in Orange County, New York, in the Hudson River Valley in 1724. Her parents had emigrated from Scotland and the family lived on a large estate where they observed many plants and animals unfamiliar to them. Jane was an intelligent and curious child and even though women were not generally encouraged to embark on serious studies, her father helped her to study and draw the plants that surrounded them. He also taught her the system developed by the Swedish botanist, Carl Linnaeus, to classify plants.

Jane soon began corresponding with botanists in both Europe and America. She was a skilled illustrator and developed a technique for making ink impressions of leaves. Between 1753 and 1758, she catalogued more than 300 species of plants that she found in the area near her home. She also asked Native Americans and some of the Dutch settlers in the region about medicinal uses for these plants and was able to share that information with other scientists. Her scientific work was cut short when she married and a few years later died, apparently in childbirth, at the age of 42. Unfortunately, few of her letters have been preserved and we know about Jane Colden mainly through comments about her written by better-known botanists. Her only remaining manuscript is at the British Museum in London.

Jane Colden drawings

It is inspiring to read about the way Jane Colden and other 18th century scientists exchanged information and specimens across national boundaries. Without these exchanges, difficult though communication was in those days, science would not have enriched the lives of so many people. Have we lost the ability to do that just when global cooperation is most urgently needed?

Now that we have established lightning-fast communication that allows information to flow across the globe, it is time for many countries to work together even more than in the past. The threats brought by global warming require worldwide cooperation. Let’s hope the scientists and private citizens will be able to keep the work going without allowing political struggles to build walls between countries. Tariffs and secrecy may protect corporations but they often work against the welfare of ordinary people who depend on shared knowledge to maintain their wellbeing. We have to remember that we’re all in this together on one small, troubled planet.    

Why Are Humans Such Slow Learners?

Here in California, the prospect of Thanksgiving has been tarnished by the series of disasters that have hit the state. Wildfires are raging in both Northern and Southern  parts of the state. And the effects of the fires are felt widely. Even in San Francisco, which is miles away from the nearest fire, the smell of smoke hovers over us and this week the sky has an ominous yellowy-greenish hue, schools are closed, people wear masks and still they cough.

The wildfires are only one example of the way the natural world has been changing our view of the power of nature. The long, hot summer and disastrous hurricanes have affected the lives of people throughout the country. All the measures that we have taken to tailor weather to our preferences are failing us. We can’t spend all of our time hunkering down in our air-conditioned houses and cars. Nature is taking its revenge and forcing us to consider how we live and work.

Climate change is an undeniable fact, yet we still elect politicians who refuse to recognize what’s going on. Why do some politicians find it so difficult to accept scientific facts?  And why do voters, even in a year of Democratic triumphs like these midterms, continue to vote against measures that might help? A recent article in the Atlantic Monthly tells us how difficult it has been to confront the realities of climate change.

It’s not as though the idea of climate change hasn’t been discussed for years. The medieval idea that the world is unchanging and that human beings have no influence on it was challenged more than 200 years ago by Alexander von Humboldt, one of the greatest scientists the world has ever known, although much of his work has been forgotten.

Born in 1769, Humboldt traveled to South America in 1800 to explore nature and culture in the Spanish colonies there. When he saw the changes that Europeans has brought to the country by cutting down forests and cultivating lands, he developed his theories of how men affect climate. “When forests are destroyed, as they are everywhere in America by the European planters, …the springs are dried up or become less abundant.”  He noted how this allowed the soil to be washed away during heavy rains, causing erosion and a loss of fertile soil

Knowledge is a slow-growing plant, but Humboldt was one of those people who planted ideas that have blossomed during the centuries since he started his explorations. We are lucky this year to have a new biography of Alexander von Humboldt available. Andrea Wulf, has explored Humboldt’s life and ideas in The Invention of Nature: Alexander von Humboldt’s New World. I highly recommend it to anyone interested in seeing how scientific ideas have developed over the years and learning more about the people who have given us our modern view of the world. 

Scientists have known for many years that people are changing the world and that much of that change makes the world smaller and less livable. Our demand for fossil fuels have fostered changes in the climate that threaten us all. For a while there was hope that America would act to lower our carbon impact, but instead we are turning away from all the facts that scientists have been explaining to us for centuries. For a recent update on how the world is going, you can read Bill McKibbon’s article in the current New Yorker magazine.

Perhaps if enough people read that article, Americans will come together and push their politicians into action. Then by next Thanksgiving we might truly have something to be thankful for.

The U.S. vs. Mother Nature

As yet another hurricane brings torrents of rain and flooding to another part of the

flood Hawaii
Flood in Hawaii 2018

United States—this time the Carolinas—I can’t help but think how the attitudes of many Americans toward nature have changed over the years. Many of our leaders now seem to see nature as a foe to be defeated and conquered instead of as a priceless resource to be studied and understood.

During the early post-Revolutionary years, most of the leaders who shaped the country were awestruck by the riches of their new land. I have been reading a book about one of these Americans, David Hosack. He is hardly a familiar name, although his achievements during the early post Revolutionary period are still important. The book is called American Eden: David Hosack, Botany and Medicine in the Gardens of the Early Republic by Victoria Johnson.

David Hosack was a doctor, who is perhaps most often remembered for the role he played in attending Alexander Hamilton after the fatal duel between Aaron Burr and Hamilton. He was unable to save Hamilton’s life after that duel, but he was responsible for saving many other lives both through his own treatments and through the medical American Eden01students he trained and the cures he discovered. Unlike many of our current leaders, Hosack had great respect for the value of science and of studying how medical treatment could be improved through learning more about the characteristics of plants.

One of Hosack’s most important legacies was the establishment of a famous botanical garden, called Elgin Garden located on the current site of Rockefeller Center. At the time the garden was established, it was far uptown from the small city of New York in lower Manhattan. For years Hosack taught at Columbia College and took his students through the gardens to learn about the medicinal qualities of plants. He established ties with fellow scientists in Europe, especially England and Scotland, and exchanged both information and plants with them. American leaders, including Thomas Jefferson, honored Hosack’s work and sometimes exchanged plants with him. Like most leaders of his generation, Hosack understood the value of working internationally to improve the lives of Americans and others.

Generation after generation as the United States grew and expanded from the Atlantic to the Pacific coasts of North America, much of its growth and prosperity was fueled by scientific advances. Land grant universities trained young people to understand science and improve agriculture. As the country grew more populated, farsighted leaders like Theodore Roosevelt understood the necessity of preserving the natural landscapes and resources of the continent and established National Parks.

Until recently government, scientists and community leaders worked together to preserve the natural riches and to enable people to lead better lives. Now suddenly, even as more and more scientists and ordinary citizens recognize the threat of climate change climate change smokestackbrought on by human activities, many of our leaders have lost their way. Instead of working to mitigate the dangers of greenhouse gases, we are encouraging corporations to spew more noxious fumes in the air and make the world less safe for children as well as the rest of us. Instead of working with other countries to improve the world, our leaders want to tear up treaties in the hope of immediate profits for a few wealthy corporations. Instead of encouraging scientists to study our changing world, many leaders are cutting funding for education and restricting scientific research. What has happened?

Do we really want our shorelines to erode? Do we want to increase the number of children and adults who suffer from asthma? Is it more important for a corporate executive to buy another jet plane than to preserve the fish, birds, and other disappearing wildlife? That is something that everyone who votes in November should consider. And everyone who could vote but doesn’t should feel a personal responsibility for failing to protect the country so many of us celebrate.

 

What’s the weather like?

Here in northern California we have been preoccupied by the wildfires that are threatening homes and property in many parts of the state. Even in San Francisco, which is miles away from the nearest fire, the vague smell of smoke hovers over us and on weather_Wildfiressome days the sky in the morning has an ominous yellowy-greenish hue. City dwellers are sometimes thought to be immune to changes in the natural world, but nature has intruded on us this year and we have become preoccupied by it.

The wildfires in so many western states—made much worse by the hot, dry weather that has prevailed—are only one example of the way the natural world has been changing our view of the power of nature. The long, hot summer and the disastrous hurricanes have affected the lives of people throughout the country. And the hurricane season has only started. All the measures that we have taken to tailor weather to our preferences are failing us. We can’t spend all of our time hunkering down in our air-conditioned houses and cars. Nature is taking its revenge and forcing us to consider how we live and work.

Last year when I visited London, I bought a book called Weatherland: Writers and artists under English Skies. The author, Alexandra Harris, traces the history of the way writers and artists have been influenced by English weather over the centuries. The ever-changing British weather has encouraged a deep interested in tracking the vagaries of

changes in the weather. Even architecture has been impacted. The warm summers of the 1720s and 1730s, as reported by Harris, have been suggested as an incentive to introduce the neoclassical style buildings in cities like Bath. Although as she explains the “high ceilings and open colonnades were considerably less appealing” when the average chilly English climate reappeared in later years.

The 19th century was one that brought dampness and rain to much of England. Byron wrote “Morn came and went and came, and brought no day,/And men forgot their passions in the dread…” As the century went on and cities grew in size and density, rain and fog became a part of the plot as in Charles Dickens’s Bleak House  in which rain falls throughout the first twelve chapters and weather seems to become an integral character in the story.

It wasn’t until the 20th century that the influence of people on the weather was recognized as being as important as the influence of weather on people. The use of fossil fuels and the growth

weather_smog1952
Smog 1952

of manufacturing led to increasing episodes of smog both in England and America. The culmination, for London, was the great smog of  December 1952 which killed several thousand people. At last the general public began to pay attention and the first Clean Air Act was passed in 1956.

Now we are again to be in an era when mankind is impacting weather so strongly that once again people throughout the world are in danger. Climate change is causing rising temperatures for oceans and land. Unprecedented storms are increasing in numbers and violence. Deserts are expanding in Africa and coastlines are receding as the oceans rise. Although our national government has become reluctant to act on the clear danger, if enough people push hard enough, we will be able to stop the reckless policies of our so-called leaders and insist on regulations to limit the worst effects of these changes.

Reading Wonderland won’t give you a background in climate science, but it is a great reminder of how important weather has always been in the life of human beings.

 

The climate, it’s a changing…

It has taken me two days to absorb the information that President Trump has decided the United States will drop out of the Paris Climate Accord, which was signed with such cheering only last year. I have to wonder how much the President looks around the world that both he and I live in.

The first time I really noticed how a changing climate can affect people’s lives is when I visited Mali in 2003. We flew to the small airport in Timbuktu passing over miles of empty sandscapes. Timbuktu looked like no place else I had ever seen–the buildings are

Timbuktu
Timbuktu 2003

made of mud or stucco, and the roads and open spaces are covered with sand. It’s impossible to tell whether the roads are paved or not. They curve around the city and our drivers zoomed around buildings, donkeys, children, men in long robes and women in subdued colors walking along the streets. Everything tastes slightly of sand; even the bread had a grittiness from the fine sand that blew into the dough as it was being prepared. Our guide told us that people who live in the city often lost their teeth early because the sand in their food slowly grinds down the enamel.

The following year, I went to Argentina and saw the glaciers of Patagonia. Many of them are now sliding inexorably into the sea. The loud crack of huge chunks of ice breaking off and being swallowed up by the ocean punctuated our trip. Now, more than ten years

Blue glacier

later, the ice is breaking off even faster. Huge cracks are appearing in the glaciers of Antarctica. How can anyone believe that climate is not changing?

It’s not as though the idea of climate change hasn’t been discussed for many years. The medieval idea that the world is unchanging and that human beings have no influence on it was challenged more than 200 years ago by Alexander von Humboldt, one of the greatest scientists the world has ever known.

Humboldt traveled to South America in 1800 to explore nature and culture in the Spanish colonies there. When he saw the changes that Europeans has brought to the country by cutting down forests and cultivating lands, he developed his theories of how men affect climate. “When forests are destroyed, as they are everywhere in America by the European planters, …the springs are dried up or become less abundant.”  He noted how this allowed the soil to be washed away during heavy rains, causing erosion and a loss of fertile soil. He did not know that in the years that followed his visit, mankind would change the landscape and the climate even more by all the carbon emissions from the cars, airplanes, and factories that people have introduced all over the world.

Knowledge is a slow-growing plant, but Humboldt planted new ideas that have blossomed during the centuries since he started his explorations. In a recent book, Andrea Wulf, has explored Humboldt’s life and ideas in The Invention of Nature: Alexander von Humboldt’s New World. I highly recommend it to anyone interested in seeing how scientific ideas have developed over the years and how long it takes to persuade people to accept new knowledge and to change their ideas.

The recent five-year drought in California has brought home to me the conviction that we should all think about what we can do to prevent climate change from destroying our fragile planet. Droughts cause deserts to be formed and to expand. A warming ocean creeps up our shores and makes larger and larger areas unlivable. Violent storms eat away at cliffs destroying homes  and exposing communities to danger. The cliffs in the picture below are in Pacifica, California.

No matter what our leaders may tell us, all of us as citizens must look for ourselves and decide what we can do as individuals and communities to keep our planet safe for the future.Pacifica_2016

Rachel Carson’s Tangled Web

In the midst of the deluge of news coming out of the White House this past week, many environmentalists have paid tribute to Rachel Carson, whose 1962 book Silent Spring has silent-springbeen hailed by many as the impetus that started America’s environmental movement. Carson’s book called attention to the impact of the insecticide DDT on the deaths of birds, fish, and other animals up the food chain. The book called for an end to the indiscriminate spraying of DDT on crops, in houses, and on children and other people who spent time outdoors.

After the book was published, it was predictably attacked by the chemical industry, especially Dupont  Chemical Company which produced DDT. One Dupont scientist, Robert White-Stevens, was particularly vehement: According to White-Stevens, “If man were to follow the teachings of Miss Carson, we would return to the Dark Ages, and the insects and diseases and vermin would once again inherit the earth.” Rachel Carson was called to testify before Congress on the validity of her findings, which she defended strongly despite being critically ill at the time. She died of cancer in 1964, less than two years after the publication of her most famous book.

Silent Spring was widely publicized, appearing as a series of articles in the New Yorker as well as being the subject of a CBS documentary. The public soon embraced the idea of the rachel-carson-illusdanger of pesticides and other technological advances in science. The use of DDT on crops was banned in the United States and in 1970 the Environmental Protection Agency was set up to monitor the effect of various scientific advances on the lives of Americans.

Controversy continues, however. When Google paid tribute to Rachel Carson on the 50th anniversary of her death, Breitbart News asked the question: “Will Google be paying tribute to any of the other mass killers of the 20th century? Hitler? Stalin? Mao? Pol Pot? Probably not. But then, none of the others have had the benefit of having their images burnished by a thousand and one starry-eyed greenies.” 

The idea of Rachel Carson as a mass murderer comes from the fact that deaths from malaria, which had been decreasing with the use of DDT to kill malarial mosquitoes, began to climb. But the increase seems to have been due more to the fact that mosquitoes evolved so that DDT no longer killed them. And critics of Carson fail to recognize that she never suggested that all pesticides be abolished. Environmental issues are complex and simple solutions seldom solve them.

The truth is that science is difficult. Discovering the truth about the natural world takes time and requires the cooperation of many scientists. And trying to use the facts of science to make the world better usually has mixed results. Rachel Carson was right—pesticides do disrupt the natural order and kill birds as well as insects. And other scientists are also right in saying that malaria is a terrible disease and that killing the mosquitoes that carry the disease saves human lives. We need to find a balance between the two. Gradually scientists are finding new pesticides which are again bringing down the rates of malaria around the world.

The struggle over science continues. Climate change is one of the most hotly contested scientific issues today, especially because President Trump has said that he does not believe in the concept of climate change caused by human activities . His nominee for the head of the EPA is a man who has scoffed at the need for the U.S. and the world to make any effort to climate-changeaddress climate change. On January 24, 2017, according to the New York Times, “President Donald Trump’s administration has instructed the Environmental Protection Agency to remove the climate change page from its website, two agency employees told Reuters, the latest move by the newly minted leadership to erase ex-President Barack Obama’s climate change initiatives.”

As citizens we need to recognize the complexities of science and accept that changes are necessary even though they may be uncomfortable. Old jobs and old ways of life may disappear, but new ones will be found. We must protest when government officials forbid scientists to study how the world works and to make projections about what will happen in the future.

This blog is called Teacups and Tyrants. Most of my posts have focused on the quieter teacup parts of life, but recently the country has seen the growth of tyrants. From now on I expect to focus more on the harsher side of life and the threats that tyrants pose for our future.

Who told us about climate change?

Just a few miles from where I live in San Francisco, the effects of climate change are obvious to everyone. This winter’s record El Nino has brought rain storms that have eroded beach communities along the Pacific. This photo from the San Francisco Chronicle Pacifica_2016shows how some of the homes in the city of Pacifica are teetering on the edge of a cliff over the ocean. Scientists are predicting that climate change will bring stronger and harsher El Nino storms in years to come because of the warming oceans caused in large part by human activity. Anyone who reads newspapers or watches news on TV know that this is true, yet somehow many of the Republican candidates who want to lead the country cannot seem to accept the facts.

Climate change is an undeniable fact, yet we still get candidates saying things like this: “If you look to the satellite data in the last 18 years there has been zero recorded warming. Now the global warming alarmists, that’s a problem for their theories. Their computer models show massive warming the satellite says it ain’t happening. We’ve discovered that NOAA, the federal government agencies are cooking the books,” Ted Cruz is quoted as saying that in 2015. Why do some politicians find it so difficult to accept scientific facts?

It’s not as though the idea of climate change hasn’t been discussed for years. The medieval idea that the world is unchanging and that human beings have no influence on it was challenged more than 200 years ago by Alexander von Humboldt, one of the

greatest scientists the world has ever known, although much of his work has been forgotten.

Knowledge is a slow-growing plant, but Humboldt was one of those people who planted ideas that have blossomed during the centuries since he started his explorations. One of the other ideas that he developed in South America was a hatred of slavery, because he saw the cruelty of the European practice of enslaving native peoples. Slowly many of his Humboldt in his libraryideas have been accepted by mainstream thinkers. Slavery has disappeared in much of the modern world.  Let’s hope that more of the climate change deniers will continue to think about the questions and ideas that he raised.

We are lucky this year to have a new biography of Alexander von Humboldt available. Andrea Wulf, has explored Humboldt’s life and ideas in The Invention of Nature: Alexander von Humboldt’s New World. I highly recommend it to anyone interested in seeing how scientific ideas have developed over the years and learning more about the people who have given us our modern view of the world.
