Hottest May on Record. Of Course, it’s 2020

CNBC:

The Earth had its hottest May ever last month, continuing an unrelenting climate change trend as 2020 is set to be among the hottest 10 years ever, scientists with the Copernicus Climate Change Service announced on Friday. 

It’s virtually certain that this year will be among the top hottest years in recorded history with a higher than 98% likelihood it will rank in the top five, according to the National Oceanic and Atmospheric Administration.

“The last month has been the warmest May on record globally and this is unquestionably an alarming sign,” said Freja Vamborg, a scientist at Copernicus Climate Change Service, an intergovernmental agency that supports European climate policy.

“Even more concerning is the fact that average temperatures of the last 12 months have become one of the hottest 12-month periods ever recorded in our data set,” she said. 

The most above-average temperatures were recorded over parts of Siberia — where temperatures were up to 10 degrees Celsius above average — as well as Alaska and Antarctica, according to the new research.

The last 12-month period, from June 2019 to May 2020, was nearly 0.7 degrees Celsius (about 1.3 degrees Fahrenheit) warmer than average. Globally, May was 0.63 degrees Celsius (about 1.1 degrees Fahrenheit) warmer than the average May recorded from 1981 to 2010. 

The continuous upward trend in global temperatures results from greenhouse gas emissions that change the climate

2019 was the second-hottest year ever, capping off the world’s hottest decade in recorded history. And six of the warmest years on record were during the past decade. 

The rising temperatures are accompanied by countless climate disasters, including rapid ice melt in Greenland and Antarctica, devastating wildfires from Australia to California and more intense and frequent hurricanes and heat waves. 

Hindustan Times:

Investigators have determined that the leakage of of 20,000 tons of diesel (about 150,000 barrels) from a reservoir at a power plant in Russia’s Far North was caused by damage from thawing permafrost—just the latest sign of the catastrophic effects climate change is having in the Arctic.

“Entire cities and roads were built on permafrost,” said Guido Grosse, head of the permafrost research unit at the Alfred Wegener Institute in Potsdam, Germany. “When permafrost thaws, the ice deep in the ground that has been there for thousands of years melts, and you lose stability. That has an impact on infrastructure.”

Infrastructure in Siberia, northern Canada and Alaska is usually built on pillars that stand on top of the permafrost. With temperatures rising at twice the global average rate in the Arctic Circle, the frozen ground is thawing and causing cracks in roads and buildings.

About half of Russia, the world’s largest country, is covered with permafrost. But while Soviet scientists have developed ways to refreeze the ground in cases where structural stability is at stake, they lag North America in preparing for a future with no permafrost at all.

    President Trump’s claim that the U.S. has the cleanest air and water in the world has been widely refuted by statistics showing harmful levels of pollution. Now, a new biannual ranking released by researchers at Yale and Columbia finds that the U.S. is nowhere near the top in environmental performance.

    “The last month has been the warmest May on record globally and this is unquestionably an alarming sign,” said Freja Vamborg, a scientist”. Would have astonished me if it had gone the other way like “The last month has been one of the coolest Mays on record globally in spite of there being a global heater averaging 396,000 gigawatts running for the last 22 years and right now. Normally, with 396,000,000,000 room heaters in a room we scientists expect things to cool down a bit”said Freja Vamborg, a scientist.


  3. Possibly, a fraction of the immediate surface temperature is attributable to a decrease in aerosols.

    Certainly causing a stir in Siberia. . . . .

    A state of emergency was declared in three districts of vast Krasnoyarsk region where villages were flooded, houses destroyed and three bridges washed away by water after days of stormy rains.
