Asia remained the world’s most disaster-hit region from weather, climate and water-related hazards in 2023. Floods and storms caused the highest number of reported casualties and economic losses, whilst the impact of heatwaves became more severe, according to a new report from the World Meteorolog ... ical Organization (WMO). The State of the Climate in Asia 2023 report highlighted the accelerating rate of key climate change indicators such as surface temperature, glacier retreat and sea level rise, which will have major repercussions for societies, economies and ecosystems in the region. In 2023, sea-surface temperatures in the north-west Pacific Ocean were the highest on record. Even the Arctic Ocean suffered a marine heatwave. Asia is warming faster than the global average. The warming trend has nearly doubled since the 1961–1990 period. more

La tendencia al calentamiento en América Latina y el Caribe continuó en 2021. La tasa media de aumento de las temperaturas fue de aproximadamente 0,2 °C por década entre 1991 y 2021, en comparación con los 0,1 °C por década registrados entre 1961 y 1990.En 2021, la temperatura se situó por e ... ncima de la media de 1981-2010 en todas las subregiones, habiéndose registrado la anomalía máxima de +0,59 (±0,1 °C) en la región de México y América Central, lo que corresponde a +0,97 (±0,1 °C) por encima del período de referencia de 1961-1990 de la OMM para el cambio climático. more

Climate change triggers mounting food insecurity, poverty and displacement in Africa

Concentrations of the major greenhouse gases, CO2 , CH4 , and N2 O, continued to increase despite the temporary reduction in emissions in 2020 related to measures taken in response to COVID-19. 2020 was one of the three warmest years on record. The past six years, including 2020, have been the si ... x warmest years on record. Temperatures reached 38.0 °C at Verkhoyansk, Russian Federation on 20 June, the highest recorded temperature anywhere north of the Arctic Circle. The trend in sea-level rise is accelerating. In addition, ocean heat storage and acidification are increasing, diminishing the ocean’s capacity to moderate climate change. more

Compared to the previous five-year assessment period 2011–2015, the current five-year period 2015–2019 has seen a continued increase in carbon dioxide (CO2 ) emissions and an accelerated increase in the atmospheric concentration of major greenhouse gases (GHGs), with growth rates nearly 20% high ... er. The increase in the oceanic CO2 concentration has increased the ocean’s acidity. The five-year period 2015–20191 is likely to be the warmest of any equivalent period on record globally, with a 1.1 °C global temperature increase since the pre-industrial period and a 0.2 °C increase compared to the previous five-year period. more

The 2019 edition treating data for 2018 marks sustained international efforts dedicated to reporting on, analysing and understanding the year-to-year variations and long-term trends of a changing climate.
