David Suzuki: ‘It’s very, very late and urgent’ to take climate action if we want to prevent human extinction
The key to winning victories against big oil? Perseverance
Bill McKibben writes: Vermont’s Middlebury College announced on Wednesday that it was divesting its holdings in fossil fuel companies. Given that more than a thousand institutions with endowments totaling more than $8tn have made similar pledges, it might not seem so newsworthy – but Middlebury was one of the first to reverse course. Six years ago the college flatly rejected divestment, and the shift makes it clear why big oil’s purchase on our economy and our society is eroding. Much…
January was Australia’s hottest month since records began
Australian Associated Press reports: January was Australia’s hottest month on record, the Bureau of Meteorology has said. The mean temperature last month, averaged across the country, exceeded 30C for the first time for any month. A senior climatologist at the bureau, Andrew Watkins, said January’s heat was unprecedented. “We saw heatwave conditions affect large parts of the country through most of the month, with records broken for both duration and also individual daily extremes,” he said on Thursday.

How the geography of climate damage could make the politics less polarizing
Mark Muro, David G. Victor, and Jacob Whiton write: As a new Congress and the 2020 presidential election cycle gear up, much of Washington is likely to focus on topics where political polarization is high. Yet there may be surprises. Take climate change, a top priority for many Democrats. The standard story is that the high-tech “blue” states are pushing a green wave of massive investment to cut emissions of gases that cause climate change. Meanwhile, the GOP-leaning “red” states…
Extreme weather events could worsen climate change
E&E News reports: Droughts, heat waves and other extreme climate-related events are growing concerns in a warming world. Studies have found climate change is already fueling an increase in some extreme events and that they’re likely to worsen as temperatures continue to climb. Now, new research suggests the reverse may also be true—these events, themselves, could also worsen climate change. Weather and climate events tend to affect the amount of moisture contained in the soil, according to the study published…
As climate warms, plants will absorb less carbon dioxide
The New York Times reports: The last time the atmosphere contained as much carbon dioxide as it does now, dinosaurs roamed what was then a verdant landscape. The earth’s lushness was at least partly caused by the abundance of CO₂, which plants use for photosynthesis. That has led to the idea that more CO₂ in the atmosphere could create a literally greener planet. Today, plants and soil around the world absorb roughly a quarter of the greenhouse gases that humans…
Record number of Americans are worried about climate change
The New York Times reports: A record number of Americans understand that climate change is real, according to a new survey, and they are increasingly worried about its effects in their lives today. Some 73 percent of Americans polled late last year said that global warming was happening, the report found, a jump of 10 percentage points from 2015 and three points since last March. The rise in the number of Americans who say global warming is personally important to…
Corporate America sees opportunities to profit from diseases and disasters caused by climate change
Bloomberg reports: Climate change isn’t all downside for the largest U.S. companies. Many of those that filed reports with CDP [formerly known as the Carbon Disclosure Project] said they believe climate change can bolster demand for their products. For one thing, more people will get sick. “As the climate changes, there will be expanded markets for products for tropical and weather related diseases including waterborne illness,” wrote Merck & Co. The company didn’t respond to a request for comment. More…
Greenland’s ice melting faster than scientists previously thought
The Guardian reports: Greenland is melting faster than scientists previously thought, with the pace of ice loss increasing four-fold since 2003, new research has found. Enormous glaciers in Greenland are depositing ever larger chunks of ice into the Atlantic ocean, where it melts. But scientists have found that the largest ice loss in the decade from 2003 actually occurred in the southwest region of the island, which is largely glacier-free. This suggests surface ice is simply melting as global temperatures…
Sixfold increase in ice loss from Antarctica since 1970s, new research finds
The Washington Post reports: Antarctic glaciers have been melting at an accelerating pace over the past four decades thanks to an influx of warm ocean water — a startling new finding that researchers say could mean sea levels are poised to rise more quickly than predicted in coming decades. The Antarctic lost 40 billion tons of melting ice to the ocean each year from 1979 to 1989. That figure rose to 252 billion tons lost per year beginning in 2009,…
Hotter oceans mean we are in the emergency phase of climate change
Eric Holthaus writes: The Earth’s surface is 70 percent water, but even that underestimates how vital ocean health is to our planet’s ability to maintain life. Recent results from scientists around the world only further confirm that our waterworld is in serious danger. Last week, a bombshell study confirmed that the oceans are warming 40 percent faster than many scientists had previously estimated. The finding partially resolved a long-running debate between climate modelers and oceanographers. By measuring the oceans more…
As international cooperation tackling climate change becomes more urgent, global divisions widen
The Guardian reports: Growing tension between the world’s major powers is the most urgent global risk and makes it harder to mobilise collective action to tackle climate change, according to a report prepared for next week’s World Economic Forum in Davos, Switzerland. The WEF’s annual global risks report found that a year of extreme weather-related events meant environmental issues topped the list of concerns in a survey of around 1,000 experts and decision-makers. But with Donald Trump announcing protectionist measures…
Are we living through climate change’s worst-case scenario?
Robinson Meyer writes: The year 2018 was not an easy one for planet Earth. Sure, wind and solar energy kept getting cheaper, and an electric car became America’s best-selling luxury vehicle. But the most important metric of climatic health—the amount of heat-trapping gas entering the atmosphere—got suddenly and shockingly worse. In the United States, carbon emissions leapt back up, making their largest year-over-year increase since the end of the Great Recession. This matched the trend across the globe. According to…
New plant-focused diet would ‘transform’ planet’s future
The Guardian reports: The first science-based diet that tackles both the poor food eaten by billions of people and averts global environmental catastrophe has been devised. It requires huge cuts in red meat-eating in western countries and radical changes across the world. The “planetary health diet” was created by an international commission seeking to draw up guidelines that provide nutritious food to the world’s fast-growing population. At the same time, the diet addresses the major role of farming – especially…
Ocean warming is accelerating faster than thought, new research finds
The New York Times reports: Scientists say the world’s oceans are warming far more quickly than previously thought, a finding with dire implications for climate change because almost all the excess heat absorbed by the planet ends up stored in their waters. A new analysis, published Thursday in the journal Science, found that the oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago. The researchers also concluded that ocean temperatures have…
U.S. carbon emissions surged in 2018 even as coal plants closed
The New York Times reports: America’s carbon dioxide emissions rose by 3.4 percent in 2018, the biggest increase in eight years, according to a preliminary estimate published Tuesday. Strikingly, the sharp uptick in emissions occurred even as a near-record number of coal plants around the United States retired last year, illustrating how difficult it could be for the country to make further progress on climate change in the years to come, particularly as the Trump administration pushes to roll back…
