Slow-Moving Atlantic Storms Like Imelda and Dorian are Growing More Common | Weather Underground

melda, Dorian, Florence, Harvey, and Idai are examples of storms we have been seeing more often in recent decades: ones that move more slowly over land, resulting in increased flooding and damage. The forward speed of tropical cyclones (which includes all hurricanes, tropical storms, and tropical depressions) has decreased globally by about 10% since 1949, according to a 2018 paper in the journal Nature by NOAA hurricane scientist Dr. Jim Kossin. As a result of their slower forward motion, these storms are now more likely to drop heavier rains, increasing their flood risk. Most significantly, the study reported a 20% slow-down in storm translation speed over land for Atlantic storms, a 30% slow-down over land for Northwest Pacific storms, and a 19% slow-down over land for storms affecting the Australia region.

CNN climate forum: Warren blasts the plastic straw debate as a fossil fuel industry distraction tactic – Vox

“Oh, come on, give me a break,” Warren said in response to the lightbulb question, in one of the breakout moments of the night. “This is exactly what the fossil fuel industry wants us to talk about. ... They want to be able to stir up a lot of controversy around your lightbulbs, around your straws, and around your cheeseburgers, when 70 percent of the pollution, of the carbon that we’re throwing into the air, comes from three industries.”

Whatever Happened To The Mysterious Kidney Disease Striking Central America?

Whatever Happened To The Mysterious Kidney Disease Striking Central America?

The disease, which has made kidney failure the second-leading cause of death in Nicaragua and El Salvador, was first reported in the 1990s. It was a strange new type of kidney failure. Sugar cane cutters from plantations in Nicaragua, El Salvador and Guatemala were turning up at clinics with end-stage kidney disease. Some had been in what seemed to be perfect health just a few years before. These laborers didn't have diabetes or hypertension or other factors that might explain why their kidneys were failing.

Greenhouse Gases Reach Unprecedented Level – EcoWatch

Greenhouse Gases Reach Unprecedented Level – EcoWatch

A bleak new federal report found that carbon dioxide in the atmosphere rose to levels the world has not seen in at least 800,000 years, highlighting the irreversible and mounting deleterious effects of human activity on the planet, as ABC News reported.

Global carbon dioxide concentrations reached a record of 407.4 parts per million during 2018, the study found. That is 2.4 ppm greater than 2017 and "the highest in the modern instrumental record and in ice core records dating back 800,000 years," the report said, according to CNN.

It wasn't just the amount of carbon dioxide that set record levels. Other greenhouse gases like methane and nitrous oxide also continued a rapid rise into the atmosphere. Together, the global warming power of greenhouse gases was 43 percent stronger than in 1990, according to the State of the Climate report released Monday by the American Meteorological Society, a division of the National Oceanic and Atmospheric Administration's (NOAA) National Centers for Environmental Information.

Arctic fires: β€œYou have to go to a different planet to find a more persistent type” – Bulletin of the Atomic Scientists

“Arctic fires—the combination of these two words is still an unusual term in my field of fire science,” says Guillermo Rein of Imperial College London. “Arctic fires are rare, but they’re not unprecedented. What is unprecedented is the number of fires that are happening. Never before have satellites around the planet seen this level of activity.”

Unprecedented, yes, but not unexplained. The Arctic is warming twice as fast as the rest of the planet, leading to the desiccation of vegetation, which fuels huge blazes. Fortunately for us, these wildfires typically threaten remote, sparsely populated areas. But unfortunately for the whole of humanity, so far this year Arctic fires have released some 121 megatonnes of carbon dioxide into the atmosphere, more than what Belgium emits annually. That beats the previous Arctic record of 110 megatonnes of carbon dioxide, set in 2004—and we’re only in July.
