Five studies, all published in the past six weeks, indicate that global heating is intensifying more rapidly than expected, giving increased urgency to our common cause.

1. Climate sensitivity measures how much global temperatures will rise for a given increase on atmospheric carbon dioxide. Getting it right is essential for predicting how hot it is going to get.

"100°F about 70 miles north of the Arctic Circle today in Siberia. That's a first in all of recorded history. We are in a climate emergency."

UNUSUALLY WARM CONDITIONS in the Arctic Circle have continued this month with temperatures reportedly hitting 30 degrees Celsius in parts of northern Russia.

BBC Weather reported the temperature today at Nizhnyaya Pesha, an area of Russia about 1,300km north of Moscow.

It follows a recent heatwave in the region, with temperatures soared to 10 degrees Celsius above average in Siberia last month, when the world experienced its warmest May on record.

Death and decay are winning in Canada's vast managed forest lands. And this victory is unleashing a rising flood of climate pollution. Put simply, our forests are dying and being cut down faster than they can grow back.

In 2018, the flood of CO2 pouring out of them reached record levels, at nearly a quarter billion tonnes of CO2 in a single year. That's more than Canada's once biggest climate pollution source — the oil and gas sector — emitted that year.

Researchers map ‘beginning of new ecosystem’ as algae bloom across surface of melting snow [Not The Green We Had In Mind!]

Scientists have created the first large-scale map of microscopic algae on the Antarctic peninsula as they bloom across the surface of the melting snow, tinting the surface green and potentially creating a source of nutrition for other species.

May 13, 2020 - The wheels we humans have set in motion concerning carbon dioxide emissions and climate change are going to take some stopping, and the latest data from Hawaii's Mauna Loa Observatory are another clear indicator of this. Scientists there have logged record concentrations of CO2 in the atmosphere, in line with a steady trend that defies even the widespread and stringent slowdown in global activity as a result of the coronavirus pandemic.

Polluting industries around the world are using the coronavirus pandemic to gain billions of dollars in bailouts and to weaken and delay environmental protections.

A recent landmark study of massive ice loss in Antarctica and Greenland fulfills the “worst case” prognosis, as outlined by the Intergovernmental Panel on Climate Change (IPCC). It’s a nightmare come true, as the impact of global warming on the planet’s most significant/biggest masses of ice multiplied six-fold in only 30 years. It wasn’t supposed to happen so unexpectedly, so suddenly.

Writer and environmentalist Bill McKibben says the adaptations we make to fight the COVID-19 outbreak could hold valuable lessons elsewhere — in the efforts to mitigate climate change. 10:56
