WMO: Global temperature is likely to exceed 1.5°C above pre-industrial level temporarily in next 5 years – “We are playing Russian roulette with our planet”

5 June 2024 (WMO) – There is an 80 percent likelihood that the annual average global temperature will temporarily exceed 1.5°C above pre-industrial levels for at least one of the next five years, according to a new report from the World Meteorological Organization (WMO). This is a stark warning that we are getting ever closer […]

From flooding in Brazil and Houston to brutal heat in Asia, extreme weather seems nearly everywhere in 2024 – “We’re departing the climate of the 20th century right now and we just can’t handle these events”

By Seth Borenstein, Suman Naishadham, Sibi Arasu, and Fabiano Maisonnave 7 May 2024 (AP News) – In sweltering Brazil, flooding killed dozens of people and paralyzed a city of about 4 million people. Voters and politicians in India, amid national elections, are fainting in heat that hit as high as 115 degrees (46.3 degrees Celsius). […]

Annual global mean surface temperature anomalies relative to 1850–1900. Global mean near-surface temperature in 2023 was 1.45 ± 0.12 °C above the 1850–1900 average. The analysis is based on a synthesis of six global temperature datasets. 2023 was the warmest year in the 174-year instrumental record in each of the six datasets. The past nine years – from 2015 to 2023 – were the nine warmest years on record. The two previous warmest years were 2016, with an anomaly of 1.29 ± 0.12 °C, and 2020, with an anomaly of 1.27 ± 0.13 °C. Globally, every month from June to December was record warm for the respective month. September 2023 was particularly noteworthy, surpassing the previous global record for September by a wide margin (0.46 °C–0.54 °C) in all datasets. The second-highest margin by which a September record was broken in the past 60 years (the period covered by all datasets) was substantially smaller, at 0.03 °C–0.17 °C in 1983. July is typically the warmest month of the year globally, and thus July 2023 became the warmest month on record. The long-term increase in global temperature is due to increased concentrations of greenhouse gases in the atmosphere. The shift from La Niña, which lasted from mid-2020 to early 2023, to fully developed El Niño conditions by September 2023 likely explains some of the rise in temperature from 2022 to 2023. However, some areas of unusual warming, such as the North-East Atlantic do not correspond to typical patterns of warming or cooling associated with El Niño. Other factors, which are still being investigated, may also have contributed to the exceptional warming from 2022 to 2023, which is unlikely to be due to internal variability alone. Graphic: WMO

WMO: Climate change indicators reached record levels in 2023 – “Sirens are blaring across all major indicators. Some records aren’t just chart-topping, they’re chart-busting. And changes are speeding-up.”

19 March 2024 (WMO) – A new report from the World Meteorological Organization (WMO) shows that records were once again broken, and in some cases smashed, for greenhouse gas levels, surface temperatures, ocean heat and acidification, sea level rise, Antarctic sea ice cover and glacier retreat. Heatwaves, floods, droughts, wildfires, and rapidly intensifying tropical cyclones […]

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 […]

World will look back at 2023 as year humanity exposed its inability to tackle climate crisis – “This year and next will be seen as the turning point at which the futility of governments in dealing with climate change was finally exposed”

By Jonathan Watts 29 December 2023 (The Guardian) – The hottest year in recorded history casts doubts on humanity’s ability to deal with a climate crisis of its own making, senior scientists have said. As historically high temperatures continued to be registered in many parts of the world in late December, the former NASA scientist […]

Pacific island sea levels rising faster than global average, WMO says – Economic damage in Southwest Pacific due to flooding in 2022 was $8.5 billion, almost triple compared to the previous year

By Gabrielle Tétrault-Farber 17 August 2023 GENEVA (Reuters) – Sea levels in the South-West Pacific are rising faster than the global average, threatening low-lying islands while heat damages marine ecosystems, the U.N. meteorological agency said on Friday. In its State of the Climate in the South-West Pacific 2022 report, the World Meteorological Organization (WMO) said […]

July 2023 sees multiple global temperature records broken – Global mean temperature temporarily exceeded the 1.5° C threshold – “The extreme weather which has affected many millions of people in July is unfortunately the harsh reality of climate change and a foretaste of the future”

8 August 2023 (C3S) – The month started with the daily global mean surface air temperature record being broken on four days in a row, from 3-6 July. All days throughout the rest of July were hotter than the previous record of 16.80°C, set on 13 August 2016, making the 29 days from 3-31 July […]

July 2023 was likely the hottest month in 120,000 years – “This anomaly is so large with respect to other record-breaking months that we are virtually certain that the month will become the warmest July on record, the warmest month on record”

By Laura Baisas 31 July 2023 (Popular Science) – Scientists are already calculating that July 2023 will be the hottest month on record—and likely the warmest month that humanity has ever experienced. The United Nations’ World Meteorological Organization (WMO) and the European Union’s Copernicus Climate Change Service announced late last week that this month’s heat was beyond record-smashing.

Climate nears point of no return as land, sea temperatures break records, experts say – “We’ve run out of time because change takes time”

By David Stanway 30 June 2023 SINGAPORE (Reuters) – The target of keeping long-term global warming within 1.5 degrees Celsius (2.7 Fahrenheit) is moving out of reach, climate experts say, with nations failing to set more ambitious goals despite months of record-breaking heat on land and sea. As envoys gathered in Bonn in early June […]
