Atmospheric carbon dioxide to pass iconic threshold in 2021 – “Emissions have now returned almost to pre-pandemic levels … The human-caused build-up of CO2 in the atmosphere is accelerating”

By Grahame Madge 8 January 2021 (Met Office) – In 2021, carbon dioxide in the atmosphere will reach levels 50% higher than before the industrial revolution, due to human-caused emissions, says a Met Office forecast. The Met Office predicts that annual average CO2 concentration at Mauna Loa Observatory, Hawaii, will be 2.29 ± 0.55 parts per million (ppm) […]

2020 tied 2016 for hottest year ever recorded – “The extraordinary climate events of 2020 show us we have no time to lose”

By Damian Carrington 8 January 2021 (The Guardian) – The climate crisis continued unabated in 2020, with the joint highest global temperatures on record, alarming heat and record wildfires in the Arctic, and a record 29 tropical storms in the Atlantic. Despite a 7% fall in fossil fuel burning due to coronavirus lockdowns, heat-trapping carbon dioxide continued to build […]

Lake Washington sockeye salmon hit record low – “In a generation, we have gone from times of plenty to these fish being on the brink of extinction”

By Lynda V. Mapes 1 January 2021 (The Seattle Times) – They are as Seattle as the Space Needle. But Lake Washington sockeye, once the largest run of sockeye in the Lower 48, are failing. The smallest run on record returned to the Cedar River in 2020, a bottoming out after years of declines. There […]

Watching Earth burn – “The war has started. We’re losing.”

By Michael Benson 28 December 2020 (The New York Times) – I have a pastime, one that used to give me considerable pleasure, but lately it has morphed into a source of anxiety, even horror: earth-watching. Let me explain. The earth from space is an incomparably lovely sight. I mean the whole planet, pole to […]

China rations electricity for millions – “The whole city was dark”

By Vivian Wang 21 December 2020 (The New York Times) – In the city of Yiwu in eastern China, the authorities turned off streetlights for several days and ordered factories to open only part-time. In coastal Wenzhou, the government ordered some companies not to heat their offices unless temperatures are close to freezing. In southern […]

Map showing highest-impact disasters in 2020, during the Covid-19 pandemic (over 250,000 people affected). The map shows only a snapshot of disasters that took place from the beginning of the month when the epidemic was declared (March 2020) for a six-month period. More than 100 disasters occurred during this period and affected over 50 million people. There were also a number of ongoing crises, including measles in DRC and droughts in parts of east and southern Africa. Graphic: IFRC

Red Cross faced record number of climate-related disasters in 2020 – “This year has tested the resilience of tens of millions of people to breaking point”

KUALA LUMPUR, 16 December 2020 (IFRC) – In a record-breaking year, the International Federation of Red Cross and Red Crescent Societies (IFRC) has responded to more climate-related disasters across Asia Pacific than any other time this century so far. The IFRC has already responded to 25 climate-related disasters in the Asia Pacific, including floods, typhoons, […]

Projected geographical shift of the human temperature niche. (Top) Geographical position of the human temperature niche projected on the current situation (A) and the RCP8.5 projected 2070 climate (B). Those maps represent relative human distributions (summed to unity) for the imaginary situation that humans would be distributed over temperatures following the stylized double Gaussian model fitted to the modern data (the blue dashed curve in Fig. 2A). (C) Difference between the maps, visualizing potential source (orange) and sink (green) areas for the coming decades if humans were to be relocated in a way that would maintain this historically stable distribution with respect to temperature. The dashed line in A and B indicates the 5% percentile of the probability distribution. Graphic: Xu, et al., 2020 / PNAS
