Global warming acceleration: hope vs. hopium – “The increase is not due to a brightening Sun, it is due to a darkening Earth”

By James Hansen, Makiko Sato, and Pushker Kharecha 29 March 2024 (Columbia University) – Accumulating evidence supports the interpretation in our Pipeline paper: decreasing human-made aerosols increased Earth’s energy imbalance and accelerated global warming in the past decade. Climate sensitivity and aerosol forcing, physically independent quantities, were tied together by United Nations IPCC climate assessments that rely […]

New study calculates climate change’s economic impact will hit $38 trillion per year by 2049 – World economy already committed to income reduction of 19 percent – World’s poorest countries will suffer 61 percent bigger income loss than the richest ones

By Seth Borenstein 17 April 2024 (AP) – Climate change will reduce future global income by about 19% in the next 25 years compared to a fictional world that’s not warming, with the poorest areas and those least responsible for heating the atmosphere taking the biggest monetary hit, a new study said. Climate change’s economic […]

Coal power plant additions and retirements for 20 countries in 2023 (GW). China added 47 GW of coal in 2023, double the amount from the rest of the world combined.

New coal plants in China soar despite President Xi’s pledge to “strictly control” dirtiest fuel – “We can’t afford blips”

By Victoria Seabrook and Daniel Dunford 11 April 2024 (Sky News) – China ramped up coal power capacity last year, according to new analysis, despite a pledge to “strictly control” the dirtiest fossil fuel. The country added 47.4 Gigawatts (GW) of new coal power in 2023, more than double the amount added by the rest […]

Emperor penguins suffered mass breeding failures in 2023 amid record low sea ice – “They’ll either freeze to death or they’ll drown”

By Gloria Dickie 25 April 2024 LONDON (Reuters) – Record low sea ice in late 2023 led to breeding failures in one-fifth of Antarctica’s emperor penguin colonies, scientists with the British Antarctic Survey said on Thursday. Emperors – the world’s largest penguin species and one of only two endemic to Antarctica — depend on sea […]

Jury awards climate scientist Michael Mann $1 million in defamation lawsuit – “I hope people think twice before they lie and defame scientists”

By Suman Naishadham 8 February 2024 WASHINGTON (AP) – A jury on Thursday awarded $1 million to climate scientist Michael Mann who sued a pair of conservative writers 12 years ago after they compared his depictions of global warming to a convicted child molester. Mann, a professor of climate science at the University of Pennsylvania, […]

Prentice Sinclair Smith a friend of home owner Dion Peronneau says she was awoken by the sound of cracking around 4 a.m. early morning Monday, as mudflow forced its way into her home in the Baldwin Hills area of Los Angeles, Tuesday, 6 February 2024. One of the wettest storms in Southern California history unleashed more than 300 mudslides in the Los Angeles area after dumping more than half of the city’s seasonal rainfall in just two days, and officials warned Tuesday that the threat hadn’t passed yet.

Global mean surface temperature difference compared with 1850-1900 average, 1850-2023. Six different data sets are shown. The 2023 annual average global temperature was 1.45 ± 0.12 °C above pre-industrial levels. Graphic: WMO

WMO confirms that 2023 smashed global temperature record – “Humanity’s actions are scorching the earth. 2023 was a mere preview of the catastrophic future that awaits if we don’t act now.”

12 January 2024 (WMO) – The annual average global temperature approached 1.5° Celsius above pre-industrial levels – symbolic because the Paris Agreement on climate change aims to limit the long-term temperature increase (averaged over decades rather than an individual year like 2023) to no more than 1.5° Celsius above pre-industrial levels. Six leading international datasets used for […]
