Global warming added a month’s worth of extra-hot days between 2023 and 2024 – “That’s a lot of toll that we’ve imposed on people. It’s a lot of toll that we’ve imposed on nature.”

By Raymond Zhong 28 May 2024 (The New York Times) – Over the past year of record-shattering warmth, the average person on Earth experienced 26 more days of abnormally high temperatures than they otherwise would have, were it not for human-induced climate change, scientists said Tuesday [Climate change and the escalation of global extreme heat […]

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 […]

Global loss of biodiversity is significantly more alarming than previously suspected – “Almost half of animals on Earth for which assessments are available are currently declining. To make matters worse, many of the animal species that are thought to be non-threatened from extinction are in fact progressively declining”

23 May 2023 (Queen’s University Belfast) – A new study led by researchers from Queen’s University Belfast has shown that the global loss of biodiversity caused by human industrialisation is significantly more alarming than previously thought. The global-scale analysis has been published in the journal Biological Reviews. The study looked at changes in the population densities […]

EIU Democracy Index 2022, global map by regime type. The average global index score stagnated in 2022. Despite expectations of a rebound after the lifting of pandemic-related restrictions, the score was almost unchanged, at 5.29 (on a 0-10 scale), compared with 5.28 in 2021. The positive effect of the restoration of individual freedoms was cancelled out by negative developments globally. The scores of more than half of the countries measured by the index either stagnated or declined. Western Europe was a positive outlier, being the only region whose score returned to pre-pandemic levels. Graphic: EIU

EIU Democracy Index 2022: Frontline democracy and the battle for Ukraine – “Overall the story is one of stagnation. This is a dismal result given that in 2022 the world started to move on from the pandemic-related suppression of individual liberties that persisted through 2020 and 2021”

1 February 2023 (EIU) – The Democracy Index, which began in 2006, provides a snapshot of the state of democracy worldwide in 165 independent states and two territories. This covers almost the entire population of the world and the vast majority of the world’s states (microstates are excluded). The Democracy Index is based on five […]

Global human population, 1700-2022. On 15 November 2022, the world’s population was estimated to reach 8 billion people, having grown by 1 billion since 2010. This is a remarkable milestone given that the human population numbered under 1 billion for millennia until around 1800, and that it took more than 100 years to grow from 1 to 2 billion. By comparison, the increase of the world’s population over the last century has been quite rapid. Despite a gradual slowing in the pace of growth, the global population is projected to surpass 9 billion around 2037 and 10 billion around 2058. Graphic: UN DESA

Global human population hits 8 billion – “We are already overstretching what we have: the housing, roads, the hospitals, schools. Everything is overstretched.”

By Dan Ikpoyi and Chinedu Asadu 15 November 2022 LAGOS, Nigeria (AP) – The world’s population will likely hit an estimated 8 billion people on Tuesday, according to a United Nations projection, with much of the growth coming from developing nations in Africa. Among them is Nigeria, where resources are already stretched to the limit. More than […]

WWF’s Living Planet Report 2022 reveals devastating 69 percent average drop in wildlife populations since 1970 – “We have cut away the very foundation of life and the situation continues to worsen”

TORONTO, 12 October 2022 (WWF-Canada) – Monitored wildlife populations — mammals, birds, amphibians, reptiles, and fish — have seen a devastating 69 per cent drop on average since 1970 according to WWF’s Living Planet Report (LPR) 2022. The report highlights the stark outlook of the state of nature and urgently warns governments, businesses and the public to take […]

Potential effect of high-temperature days on global life evaluations, 2021-2030. The estimated 17 percent drop in life evaluation by 2030 again does not take adaptability and recovery into account. However, this estimation is based on the increase in the number of high-heat days people will face globally by 2030, and is substantively meaningful. Graphic: Gallup

Rising global temperatures linked to declining wellbeing – “The analysis paints a bleak picture of the future”

By Benedicte Clouet and Nicole Willcoxon 31 August 2022 (Gallup) – As people around the world suffer through concurrent extreme heat waves, droughts, and wildfires, the effects of climate change are becoming a grim, global reality. Despite robust evidence of the environmental and economic costs of rising temperatures, far less is known about how these […]
