The man who got economists to take climate worst-case scenarios seriously

The man who got economists to take climate worst-case scenarios seriously

Bloomberg reports: What if climate change turns out to be worse than we think? That anxiety is now commonplace, but a decade ago it took an influential paper by a Harvard professor to convince the insular world of climate economists to focus more of their attention on worst-case scenarios. Martin Weitzman, who passed away this week at the age of 77, forever connected the notion of “fat tails” to the economics of climate risk. Before his 2009 paper overturned standard…

A top financier of Trump and McConnell is a driving force behind Amazon deforestation

A top financier of Trump and McConnell is a driving force behind Amazon deforestation

The Intercept reports: Two Brazilian firms owned by a top donor to President Donald Trump and Senate Majority Leader Mitch McConnell are significantly responsible for the ongoing destruction of the Amazon rainforest, carnage that has developed into raging fires that have captivated global attention. The companies have wrested control of land, deforested it, and helped build a controversial highway to their new terminal in the one-time jungle, all to facilitate the cultivation and export of grain and soybeans. The shipping…

Bolsonaro ‘most detested’ leader as he neglects the Amazon, says Brazil’s former environment minister

Bolsonaro ‘most detested’ leader as he neglects the Amazon, says Brazil’s former environment minister

The Guardian reports: Jair Bolsonaro’s neglect of the Amazon has made him “the most despised and detested leader” on earth, Brazil’s former environment minister has claimed, as the far-right leader again rebuked French president Emmanuel Macron for challenging his environmental record. Rubens Ricupero warned Bolsonaro was wreaking havoc on both Brazil’s environment and its global standing, as Bolsonaro used Facebook to scold Macron’s “inappropriate and gratuitous attacks” over the Amazon fires and insult France’s first lady. “These people are lunatics,”…

The Amazon fires are more dangerous than WMDs

The Amazon fires are more dangerous than WMDs

Franklin Foer writes: When Jair Bolosonaro won Brazil’s presidential election last year, having run on a platform of deforestation, David Wallace-Wells asked, “How much damage can one person do to the planet?” Bolsonaro didn’t pour lighter fluid to ignite the flames now ravishing the Amazon, but with his policies and rhetoric, he might as well have. The destruction he inspired—and allowed to rage with his days of stubborn unwillingness to douse the flames—has placed the planet at a hinge moment…

David Koch escaped the climate hell he helped create

David Koch escaped the climate hell he helped create

Brian Kahn writes: David Koch is dead. The billionaire died this week at age 79 of causes yet unknown. While he certainly enjoyed the fruits of his labors to deregulate U.S. industry and reduce taxes on the super-wealthy like himself, he will never have to experience the consequences of his biggest achievement: putting the entire planet on the brink of crisis in the service of enriching himself and a few other fossil fuel billionaires. And we, the people and future…

The Amazon is burning because the world eats so much meat

The Amazon is burning because the world eats so much meat

CNN reports: While the wildfires raging in the Amazon rainforest may constitute an “international crisis,” they are hardly an accident. The vast majority of the fires have been set by loggers and ranchers to clear land for cattle. The practice is on the rise, encouraged by Jair Bolsonaro, Brazil’s populist pro-business president, who is backed by the country’s so-called “beef caucus.” While this may be business as usual for Brazil’s beef farmers, the rest of the world is looking on…

Global leaders urged to divert Brazilian government from ‘suicide’ path as Amazonian rainforest burns

Global leaders urged to divert Brazilian government from ‘suicide’ path as Amazonian rainforest burns

The Guardian reports: International pressure may be the only way to stop the Brazilian government from taking a “suicide” path in the Amazon, one of the country’s most respected scientists has said, as the world’s biggest rainforest continues to be ravaged by thousands of deliberate fires. The large number of conflagrations – set illegally to clear and prepare land for crops, cattle and property speculation – has prompted the state of Amazonas to declare an emergency, created giant smoke clouds…

Climate change may change the way ocean waves impact 50% of the world’s coastlines

Climate change may change the way ocean waves impact 50% of the world’s coastlines

By Mark Hemer, CSIRO; Ian Young, University of Melbourne; Joao Morim Nascimento, Griffith University, and Nobuhito Mori, Kyoto University The rise in sea levels is not the only way climate change will affect the coasts. Our research, published today in Nature Climate Change, found a warming planet will also alter ocean waves along more than 50% of the world’s coastlines. If the climate warms by more than 2℃ beyond pre-industrial levels, southern Australia is likely to see longer, more southerly…

Fires in the Amazon, the planet at risk

Fires in the Amazon, the planet at risk

Tierra Curry writes: In Brazil, the Amazon rainforest is now burning at a record rate. The greedy, short-sighted policies of Brazil’s far-right President Jair Bolsonaro are jeopardizing indigenous peoples and countless plants and animals. Indeed, in the midst of a climate emergency, Bolsonaro’s policies to slash environmental protections and develop the Amazon for mining, ranching and farming jeopardize the future of life on Earth as we know it. North America has already lost nearly 300 species to extinction. The toll…

Brazil’s Amazon rainforest is burning at a record rate, research center says

CNN reports: Fires are raging at a record rate in Brazil’s Amazon rainforest, and scientists warn that it could strike a devastating blow to the fight against climate change. The fires are burning at the highest rate since the country’s space research center, the National Institute for Space Research (known by the abbreviation INPE), began tracking them in 2013, the center said Tuesday. There have been 72,843 fires in Brazil this year, with more than half in the Amazon region,…

How improving tools make it easier to discern climate change’s impact on specific weather events

How improving tools make it easier to discern climate change’s impact on specific weather events

MIT Technology Review reports: A week after heat waves toppled records across Europe late last month, scientists were ready to declare that climate change almost certainly drove the deadly hot stretch. On August 2, while the same heat wave was turning Greenland’s ice sheets into slush, World Weather Attribution reported that decades of greenhouse-gas emissions had raised the odds of such extreme weather by a factor of as much as 100 in some regions. “Over France and the Netherlands, such…

Climate change advancing faster than scientists previously thought

Climate change advancing faster than scientists previously thought

Naomi Oreskes, Michael Oppenheimer, and Dale Jamieson write: Recently, the U.K. Met Office announced a revision to the Hadley Center historical analysis of sea surface temperatures (SST), suggesting that the oceans have warmed about 0.1 degree Celsius more than previously thought. The need for revision arises from the long-recognized problem that in the past sea surface temperatures were measured using a variety of error-prone methods such as using open buckets, lamb’s wool–wrapped thermometers, and canvas bags. It was not until…

The New York Times reports: The White House, blindsided by a pact between California and four automakers to oppose President Trump’s auto emissions rollbacks, has mounted an effort to prevent any more companies from joining California. Toyota, Fiat Chrysler and General Motors were all summoned by a senior Trump adviser to a White House meeting last month where he pressed them to stand by the president’s own initiative, according to four people familiar with the talks. But even as the…

Amazon deforestation and Brazilian President Bolsonaro’s attack on science

Comments 0 Comment

Doug Boucher writes: Science is always a potential threat to authoritarian rulers, because it uncovers truths that contradict their lies. Recently we’ve seen a dramatic example of this conflict in Brazil, where the director of the National Institute for Space Research (INPE) has been fired by the country’s new President, Jair Bolsonaro, for releasing data showing a substantial increase in Amazon deforestation. INPE has been providing the world with measurements of deforestation, based on detailed analysis of satellite photos, for…
