Hail, America’s most under-rated climate risk has expanded footprint across the country + ‘staggering increase in heat deaths’. Fossil fuel and coal downturn

Hail! It’s America’s most underrated climate risk, Atlantic, February 9, 2021. (See bottom of this post) Wisconsin researchers in a new study find that over the last 40 years hail has expanded its footprint across the country and has become more frequent in the so-called Hail Alley stretching from Wyoming to Texas. Study: Warmer weather will increase flooding in the Columbia River Basin this …

The amount of energy accumulating in the oceans is equivalent to detonating five Hiroshima atomic bombs per second, every second over the past 25 years

6 February 2020 Earth is heating at a rate equivalent to five atomic bombs per second. This is a re-post from the Bulletin of the Atomic Scientists A recent study in the journal Advances in Atmospheric Sciences reported that the heat absorbed in Earth’s oceans reached a new record in 2019. This has been the case for almost every year over the past decade, but this information …

Impacts worsening, pace of climate change and Arctic melting increasing

The year started with fires in Australia, and all year long it seemed as if areas of the globe were aflame, culminating in California’s worst wildfire season and infernos in places that rarely burned. At the same time, there were more major tropical storms in the Atlantic than ever recorded before. Last year, Hiroko Tabuchi, a climate reporter, and Jonah Kessel, a videographer, …

Gas underestimated and we’ll get 2.3 C of heating with what we’ve emitted thus far, but we can control the speed

More Than Two Degrees of Climate Warming Is Already Locked In, New Study in Nature Climate Change Finds, by Olivia Rosane Jan. 06, 2021 Researchers estimate that a likely total of 2.3 degrees Celsius of warming is now locked in. DuKai photographer / Getty Images Existing greenhouse gases will eventually push the climate into more than two degrees of warming, according to a study published …

CO2 levels to breach 50% rise from pre-industrial era in 2021 – Met Office

Climate crisis: 2020 was hottest year ever recorded The Guardian | Damian Carrington 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 …

Faster melting, hotter temperatures predicted in new climate models

15 December 2020, Carbon Brief, New climate models suggest faster melting of the Greenland Ice Sheet AYESHA TANDON Greenland’s vast ice sheet could melt faster than previously thought over the 21st century, according to a new study. The Greenland ice sheet is the second largest mass of ice on Earth, holding enough water to raise global sea levels by 7.2 metres. …

1.5°C above baseline is now the prescribed upper limit to global warming. Global temps for first 6 months of 2020 registered 1.3°C above baseline.

Global temperature for the first six months of 2020 registered 1.3°C above baseline, a number that has new significance ever since the IPCC Special Report/2018 about the risks of exceeding 1.5°C.

Research: getting close to tipping points

November 2020. In the paper, published as a commentary in the journal Nature this month, the group of researchers summarize the latest findings related to the threat of tipping points as part of effort to “identify knowledge gaps” and suggest ways to fill them. “We explore the effects of such large-scale changes,” the scientists explain, “how quickly they might unfold …

Nearly all of Colorado is under some drought status – 20 years into megadrought in the West

Also see: https://blogs.ei.columbia.edu/2020/04/16/climate-driven-megadrought-emerging-western-u-s/ – April 20th, 2020 The Colorado Sun | evan@coloradosun.com Colorado currently is one of the drier parts of the country, and although conditions have improved in recent weeks, the long-term outlook for the state is relatively grim.  Much of Colorado continues to suffer through extreme drought, and nearly all of the state is experiencing drought, according to the …

New climate modeling shows that worst-case scenarios do not go far enough

Modelling suggests climate is considerably more sensitive to carbon emissions than thought, by Jonathan Watts 13 Jun 2020, Guardian Worst-case global heating scenarios may need to be revised upwards in light of a better understanding of the role of clouds, scientists have said. Recent modelling data suggests the climate is considerably more sensitive to carbon emissions than previously believed, and experts …
