Yale Climate Connections
During an explosive eruption, volcanoes spew ash and gases into the stratosphere. Those gases can linger and affect the climate for several years.
Rosaly Lopes of NASA’s Jet Propulsion Laboratory says generally, volcanic eruptions cause global cooling.
Lopes: “The eruption of Tambora in 1815, that actually cooled the climate so significantly that in Europe, the year 1816 was called the year without a summer.”
The cooling is driven by sulfur dioxide in the upper atmosphere, which combines with water molecules to produce sulfuric acid. When ... Read more ...

Why more CO2 could be bad news for crops - Yale Climate Connections - Science (Mar 11) |

Yale Climate Connections
Burning fossil fuels releases a lot of carbon dioxide to the atmosphere. Plants use carbon dioxide to grow, so some people mistakenly assume that rising CO2 levels will be uniformly good for crops.
But scientists warn that the reality is more complex.
Kenneth Boote is a professor emeritus at the University of Florida.
He says more CO2 can boost photosynthesis for crops, especially wheat and rice.
Boote: “And that’s good news. It gives you increased production.”
But he says if CO2 levels continue to rise, the rate at which ... Read more ...

Earlier this month, a Washington, D.C., jury held climate deniers liable for their falsehoods - a first, anywhere. The jury awarded over a million dollars in damages to climate scientist Michael Mann after finding that he had been repeatedly defamed by two bloggers.
This case did not involve a run-of-the-mill scientific disagreement or even a heated yet good-faith dispute. Instead, it combined statements both grotesque (comparing Mann to convicted child abuser Jerry Sandusky) and already-disproven (claims that Mann committed research ... Read more ...

An elephant seal dives deeper than 1,000 meters below Antarctic waters with a tiny tag affixed to its fur, helping scientists collect valuable data about climate change. In Mongolia, pigeons fly around the capital city of Ulaanbaatar, with sensors on their bodies that help gauge air pollution.
A recent Nature Climate Change article notes that more than 1,000 animal species have worn sensors to gather data in places where measurement has always been difficult. In this way, elephants, wildebeests, caribou, pigeons, seals, and other animals have helped ... Read more ...

Yale Climate Connections
In late May, the volunteer fire department in Upper Tantallon, Nova Scotia, received reports of a brush fire in the heavily wooded Halifax suburb.
Station captain Cole Jean and his six-man crew took off for the scene.
Jean: “We could immediately see the large volume of smoke - heavy black and gray smoke … and as we kind of got a little closer, we could finally see the full extent of what we were walking into.”
The fire quickly expanded into a huge inferno that raged for more than a week, destroying more than 150 homes.
It was one of ... Read more ...

Yale Climate Connections
In recent decades, wildfires have scorched forests in the western U.S. and Canada. By contributing to climate change, the world’s biggest carbon polluters made those fires far more destructive - and new research shows by just how much.
Pablo Ortiz-Partida of the Union of Concerned Scientists says carbon pollution is making the region hotter and drier, which creates more fuel for fires.
Ortiz-Partida: “It’s these hot and dry conditions that enable wildfires to burn more forest area.”
His team found that nearly 40% of the area burned by ... Read more ...

The U.S. has made progress in reducing heat-trapping carbon pollution, but extreme weather caused by climate change is harming U.S. residents in every region, according to the National Climate Assessment released in November 2023.
Here are eight things to know about the report.
The Global Change Research Act, passed in 1990, mandates that the U.S. Global Change Research Program should deliver a comprehensive climate report to “understand, assess, predict, and respond to human-induced and natural processes of global change” every four years or so. ... Read more ...

International scientists announced Tuesday, September 19, that an event like the extreme rain that led to deadly flooding in Libya earlier this month “has become up to 50 times more likely and up to 50% more intense compared to a 1.2°C cooler climate,” or the preindustrial world.
Those were among the findings of a World Weather Attribution analysis of torrential rainfall in several countries across the Mediterranean during the first two weeks of September, conducted by researchers from Germany, Greece, the Netherlands, the United Kingdom, ... Read more ...

As the climate warms, coastal communities are faced with sea level rise. But some are seeing faster rates than others.
For example, in Los Angeles, local sea level rise measures only about 1 millimeter per year. But on the coast of Louisiana, it’s about 6 millimeters a year.
“There’s a couple reasons why the rates of relative sea level rise are just very different along the United States coastline,” says William Sweet of the National Oceanic and Atmospheric Administration.
He says some parts of the ocean are naturally higher because local ... Read more ...
