Groundwater resources are drying up across the globe – “Climate variability and change can impact water supplies underground as well as above-ground”

By Matthew Rozsa 24 January 2024 (Salon) – Humans rely on groundwater for many things, but especially our food. Roughly 30 percent of all the planet’s available freshwater comes from groundwater, or water that is found underground in the spaces between rocks, soil and sand. It is primarily used for agriculture and billions of humans are dependent […]

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 energy-related CO2 emissions and their annual change, 1900-2023. Total energy-related CO2 emissions increased by 1.1 percent in 2023. Far from falling rapidly – as is required to meet the global climate goals set out in the Paris Agreement – CO2 emissions reached a new record high of 37.4 Gt in 2023. This estimate is based on the IEA’s detailed, cutting-edge region-by-region and fuel-by-fuel analysis of the latest official national energy data, supplemented by data on economic and weather conditions.

IEA: CO2 emissions in 2023 reached record high – Weather effects and continued Covid-19 reopening played a significant role in driving emissions in 2023

March 2024 (IEA) – CO2 Emissions in 2023 provides a complete picture of energy-related emissions in 2023. The report finds that clean energy growth has limited the rise in global emissions, with 2023 registering an increase of 1.1 percent. Weather effects and continued Covid-19 reopening played a significant role in driving emissions in 2023. Advanced economies saw […]

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. Globally, more coal power was added than retired in 2023. Data: GEM Global Coal Plant Tracker, January 2024. Graphic: Daniel Dunford / Sky News

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 […]

Water increasingly at the center of conflicts from Ukraine to the Middle East – “It’s very disturbing that in particular attacks on civilian water infrastructure seem to be on the rise”

By Ian James 28 December 2023 (Los Angeles Times) – Six months ago, an explosion ripped apart Kakhovka Dam in Ukraine, unleashing floods that killed 58 people, devastated the landscape along the Dnipro River and cut off water to productive farmland. The destruction of the dam — which Ukrainian officials and the European Parliament blame on Russia, […]

Climate change’s impact on coastal flooding to increase by five times over this century – “The effects of rising sea levels will put at risk decades of human development progress in densely populated coastal zones which are home to one in seven people in the world”

28 November 2023 (UNDP) – According to new data on the Human Climate Horizons platform, a collaboration between the Climate Impact Lab and UNDP, increased coastal flooding this century will put over 70 million people in the path of expanding floodplains. Latin America and the Caribbean, East Asia and the Pacific, and Small Island Developing […]

Climate-driven extreme heat may make parts of Earth too hot for humans – “If temperatures continue to rise, we will live in a world where crops are failing and millions or billions of people are trying to migrate because their native regions are uninhabitable”

By Aaron Wagner 9 October 2023 UNIVERSITY PARK, Pa. (PennState) – If global temperatures increase by 1 degree Celsius (C) or more than current levels, each year billions of people will be exposed to heat and humidity so extreme they will be unable to naturally cool themselves, according to interdisciplinary research from the Penn State […]

Map showing global water stress projected to 2050. By 2050, an additional 1 billion people are expected to live with extremely high water stress, even if the world limits global temperature rise to 1.3 degrees C to 2.4 degrees C (2.3 degrees F to 4.3 degrees F) by 2100, an optimistic scenario. Global water demand is projected to increase by 20 percent to 25 percent by 2050, while the number of watersheds facing high year-to-year variability, or less predictable water supplies, is expected to increase by 19 percent.

25 countries, housing one-quarter of the population, face extremely high water stress – By 2050, an additional 1 billion people will live with extremely high water stress

By Samantha Kuzma, Liz Saccoccia, and Marlena Chertock 16 August 2023 (WRI) – New data from WRI’s Aqueduct Water Risk Atlas show that 25 countries — housing one-quarter of the global population — face extremely high water stress each year, regularly using up almost their entire available water supply. And at least 50% of the world’s population […]

Primary energy global consumption (left) and share of global primary energy by source (right), 2000-2022. Primary energy demand growth slowed in 2022, increasing by 1.1 percent, compared to 5.5 percent in 2021, and taking it to around 3 percent above the 2019 pre-COVID level. Consumption increased in all regions apart from Europe (-3.8 percent) and CIS (-5.8 percent). Renewables’ (excluding hydro) share of primary energy consumption reached 7.5 percent, an increase of nearly 1 percent over the previous year. Fossil fuel consumption as a percentage of primary energy remained steady at 82 percent. Graphic: Energy Institute
