Economists greatly underestimate the price tag on climate change

Economists greatly underestimate the price tag on climate change

Naomi Oreskes and Nicholas Stern write: For some time now it has been clear that the effects of climate change are appearing faster than scientists anticipated. Now it turns out that there is another form of underestimation as bad or worse than the scientific one: the underestimating by economists of the costs. The result of this failure by economists is that world leaders understand neither the magnitude of the risks to lives and livelihoods, nor the urgency of action. How…

How to halt global warming for $300 billion

How to halt global warming for $300 billion

Bloomberg reports: $300 billion. That’s the money needed to stop the rise in greenhouse gases and buy up to 20 years of time to fix global warming, according to United Nations climate scientists. It’s the gross domestic product of Chile, or the world’s military spending every 60 days. The sum is not to fund green technologies or finance a moonshot solution to emissions, but to use simple, age-old practices to lock millions of tons of carbon back into an overlooked…

New evidence that an extraterrestrial collision 12,800 years ago triggered an abrupt climate change for Earth

New evidence that an extraterrestrial collision 12,800 years ago triggered an abrupt climate change for Earth

The muck that’s been accumulating at the bottom of this lake for 20,000 years is like a climate time capsule. Christopher R. Moore, CC BY-ND By Christopher R. Moore, University of South Carolina What kicked off the Earth’s rapid cooling 12,800 years ago? In the space of just a couple of years, average temperatures abruptly dropped, resulting in temperatures as much as 14 degrees Fahrenheit cooler in some regions of the Northern Hemisphere. If a drop like that happened today,…

Ocean acidification can cause mass extinctions, fossils reveal

Ocean acidification can cause mass extinctions, fossils reveal

The Guardian reports: Ocean acidification can cause the mass extinction of marine life, fossil evidence from 66m years ago has revealed. A key impact of today’s climate crisis is that seas are again getting more acidic, as they absorb carbon emissions from the burning of coal, oil and gas. Scientists said the latest research is a warning that humanity is risking potential “ecological collapse” in the oceans, which produce half the oxygen we breathe. The researchers analysed small seashells in…

How ballooning carbon emissions will impact trees

How ballooning carbon emissions will impact trees

Daniel Grossman writes: Apart from the experts, few people realize that climate change could be worse. Every year, trees, shrubs, and every other kind of plant absorb 9 billion tons of CO2—one quarter of what we let loose from our tailpipes and smokestacks—and help slow the gas’s accumulation in the atmosphere. If not for the world’s photosynthesizers, the concentration of CO2 in the air, along with Earth’s temperature, would be rising much faster than it already is. Our terrestrial plants…

In unbearable heat, Qatar has begun to air-condition the outdoors

In unbearable heat, Qatar has begun to air-condition the outdoors

The Washington Post reports: By the time average global warming hits 2 degrees Celsius, Qatar’s temperatures would soar, said Mohammed Ayoub, senior research director at the Qatar Environment and Energy Research Institute. In rapidly growing urban areas throughout the Middle East, some predict cities could become uninhabitable. “We’re talking about 4 to 6 degrees Celsius increase in an area that already experiences high temperatures,” Ayoub said. “So, what we’re looking at more is a question of how does this impact…

Exxon and oil sands go on trial in New York climate fraud case

Exxon and oil sands go on trial in New York climate fraud case

Inside Climate News reports: In late 2013, ExxonMobil faced increasing pressure from investors to disclose more about the risks the company faced as governments began limiting greenhouse gas emissions. Of the many costs climate change will impose, oil companies face a particularly acute one: the demand for their product will have to shrink. For years, Exxon had been using something called a proxy cost of carbon to estimate what stricter climate policies might mean for its bottom line. But as…

Scientists endorse mass civil disobedience to force climate action

Scientists endorse mass civil disobedience to force climate action

Reuters reports: Almost 400 scientists [now 1,140] have endorsed a civil disobedience campaign aimed at forcing governments to take rapid action to tackle climate change, warning that failure could inflict “incalculable human suffering.” In a joint declaration, climate scientists, physicists, biologists, engineers and others from at least 20 countries broke with the caution traditionally associated with academia to side with peaceful protesters courting arrest from Amsterdam to Melbourne. Wearing white laboratory coats to symbolize their research credentials, a group of…

Trump wants to erase protections in Alaska’s Tongass National Forest, a storehouse of carbon

Trump wants to erase protections in Alaska’s Tongass National Forest, a storehouse of carbon

Inside Climate News reports: The Trump Administration wants to allow logging in previously off-limit areas of Alaska’s Tongass National Forest, the U.S. Forest Service announced Tuesday, a move that could turn one of the nation’s largest carbon sinks into a source of new climate-changing emissions. The old-growth temperate rainforest contains trees that are centuries old and play a crucial role in storing carbon. In a state that is synonymous with oil production, the Tongass National Forest represents the potential for…

The world needs a massive carbon tax in just 10 years to limit climate change, IMF says

The world needs a massive carbon tax in just 10 years to limit climate change, IMF says

The Washington Post reports: A global agreement to make fossil fuel burning more expensive is urgent and the most efficient way of fighting climate change, an International Monetary Fund study found on Thursday. The group found that a global tax of $75 per ton by the year 2030 could limit the planet’s warming to 2 degrees Celsius (3.6 degrees Fahrenheit), or roughly double what it is now. That would greatly increase the price of fossil-fuel-based energy — especially from the…

Leading investment banks pump billions into fossil fuel industry

Leading investment banks pump billions into fossil fuel industry

The Guardian reports: The world’s largest investment banks have provided more than $700bn of financing for the fossil fuel companies most aggressively expanding in new coal, oil and gas projects since the Paris climate change agreement, figures show. The financing has been led by the Wall Street giant JPMorgan Chase, which has provided $75bn (£61bn) to companies expanding in sectors such as fracking and Arctic oil and gas exploration, according to the analysis. The New York bank is one of…

Companies ignoring climate crisis will go bankrupt, Bank of England governor warns

Companies ignoring climate crisis will go bankrupt, Bank of England governor warns

The Guardian reports: Companies and industries that are not moving towards zero-carbon emissions will be punished by investors and go bankrupt, the governor of the Bank of England has warned. Mark Carney also told the Guardian it was possible that the global transition needed to tackle the climate crisis could result in an abrupt financial collapse. He said the longer action to reverse emissions was delayed, the more the risk of collapse would grow. Carney has led efforts to address…

Global warming threatens two-thirds of North American bird species

Global warming threatens two-thirds of North American bird species

National Geographic reports: As they soar through the sky, birds seem blissfully impervious to the stresses of Earth. Indeed, their ability to migrate makes them more resilient to habitat disruption than less dynamic creatures. That makes the most recent annual report produced by the National Audubon Society, a nonprofit dedicated to protecting birds and their habitat, particularly startling. Released this week, the report predicts that if Earth continues to warm according to current trends—rising 3 degrees Celsius (5.4 degrees Fahrenheit)…

In its relentless pursuit of power, Silicon Valley is fueling the climate crisis

In its relentless pursuit of power, Silicon Valley is fueling the climate crisis

Rebecca Solnit writes: The climate crimes of big tech are legion. This summer the Amazon burned. Why? In part because of the policies of the new anti-environmental, anti-human-rights president, Jair Bolsonaro. How did Bolsonaro rise to prominence and then the presidency? YouTube, and certain of its algorithms that push people toward more extreme content, played a large part. As the New York Times reported in August, not long ago Bolsonaro was “a marginal figure in national politics – but a…

Google made large contributions to climate-change deniers

The Guardian reports: Google has made “substantial” contributions to some of the most notorious climate deniers in Washington despite its insistence that it supports political action on the climate crisis. Among hundreds of groups the company has listed on its website as beneficiaries of its political giving are more than a dozen organisations that have campaigned against climate legislation, questioned the need for action, or actively sought to roll back Obama-era environmental protections. The list includes the Competitive Enterprise Institute…

The literal gaslighting that helps America avoid acting on the climate crisis

The literal gaslighting that helps America avoid acting on the climate crisis

Bill McKibben writes: We’re clearly in a climate moment: it’s possible that more marchers have walked more miles in the past month than in the previous decade combined; more words have been written, more pictures published, more speeches given, more promises made, more hope expressed and anger declared. But, if the United States is going to act as it must in the years ahead, it needs to shed more than its current President. It also must stop telling itself a…
