Several other factors may have contributed to the unexpectedly unusual temperature jumps, including changes in the solar cycle, a massive volcanic eruption and a decrease in cooling aerosols, according to the report.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Temperatures are just a small part of a much bigger picture.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cData for 2024 show that our oceans continued to warm, and sea levels continued to rise. The frozen parts of Earth\u2019s surface, known as the cryosphere, are melting at an alarming rate: glaciers continue to retreat, and Antarctic sea ice reached its second-lowest extent ever recorded. Meanwhile, extreme weather continues to have devastating consequences around the world,\u201d said Celeste Saulo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tropical cyclones, floods, droughts, and other hazards in 2024 led to the highest number of new displacements recorded for the past 16 years, contributed to worsening food crises, and caused massive economic losses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIn response, WMO and the global community are intensifying efforts to strengthen early warning systems and climate services to help decision-makers and society at large be more resilient to extreme weather and climate. We are making progress but need to go further and need to go faster. Only half of all countries worldwide have adequate early warning systems. This must change,\u201d said Celeste Saulo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Investment in weather, water and climate services is more important than ever to meet the challenges and build safer, more resilient communities, she stressed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The report is based on scientific contributions from National Meteorological and Hydrological Services, WMO Regional Climate Centres, UN partners and dozens of experts.

Carbon dioxide remains in the atmosphere for generations, trapping heat.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Global Mean Near-surface Temperature<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to 2024 setting a new record, each of the past ten years, 2015-2024, were individually the ten warmest years on record.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The record temperature in 2024 was boosted by a strong El Ni\u00f1o which peaked at the start of the year. In every month between June 2023 and December 2024, monthly average global temperatures exceeded all monthly records prior to 2023.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Record levels of greenhouse gases were the primary driver, with the shift to El Ni\u00f1o playing a lesser role.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Ocean Heat Content<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Around 90% of the energy trapped by greenhouse gases in the Earth system is stored in the ocean.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 2024, ocean heat content reached its highest level in the 65-year observational record. Each of the past eight years has set a new record. The rate of ocean warming over the past two decades, 2005-2024, is more than twice that in the period 1960-2005.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ocean warming leads to degradation of marine ecosystems, biodiversity loss, and reduction of the ocean carbon sink. It fuels tropical storms and contributes to sea-level &nbsp;rise. It is irreversible on centennial to millennial time scales. Climate projections show that ocean warming will continue for at least the rest of the 21st century, even for low carbon emission scenarios.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Ocean Acidification<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Acidification of the ocean surface is continuing, as shown by the steady decrease of global average ocean surface pH. The most intense regional decreases are in the Indian Ocean, the Southern Ocean, the eastern equatorial Pacific Ocean, the northern tropical Pacific, and some regions in the Atlantic Ocean.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The effects of ocean acidification on habitat area, biodiversity and ecosystems have already been clearly observed, and food production from shellfish aquaculture and fisheries has been hit as have coral reefs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Projections show that ocean acidification will continue to increase in the 21st century, at rates dependent on future emissions. Changes in deep-ocean pH are irreversible on centennial to millennial time scales.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"723\" height=\"405\" data-attachment-id=\"391267\" data-permalink=\"https:\/\/climatescience.press\/?attachment_id=391267\" data-orig-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/07\/image-739.png?fit=768%2C430&amp;ssl=1\" data-orig-size=\"768,430\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"image\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/07\/image-739.png?fit=723%2C405&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/07\/image-739.png?resize=723%2C405&#038;ssl=1\" alt=\"Line graph depicting global ocean heat content from 1960 to 2024, showing a significant upward trend, with shaded areas representing uncertainty ranges for different studies.\" class=\"wp-image-391267\" srcset=\"https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/07\/image-739.png?w=768&amp;ssl=1 768w, https:\/\/i0.wp.com\/climatescience.press\/wp-content\/uploads\/2025\/07\/image-739.png?resize=300%2C168&amp;ssl=1 300w\" sizes=\"auto, (max-width: 723px) 100vw, 723px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Annual global ocean heat content down to 2000 m depth for the period 1960\u20132024, in zettajoules (1021 J).

The annual minimum and maximum of Antarctic sea-ice extent were each the 2nd lowest in the observed record from 1979.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The minimum daily extent of sea-ice in the Arctic in 2024 was 4.28 million km2, the 7th lowest extent in the 46-year satellite record. In Antarctica, the minimum daily extent tied for the 2nd lowest minimum in the satellite era and marked the 3rd consecutive year that minimum Antarctic sea-ice extent dropped below 2 million km2. These are the three lowest Antarctic ice minima in the satellite record.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Extreme events and impacts<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Extreme weather events in 2024 led to the highest number of new annual displacements since 2008, and destroyed homes, critical infrastructure, forests, farmland and biodiversity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The compounded effect of various shocks, such as intensifying conflict, drought and high domestic food prices drove worsening food crises in 18 countries globally by mid-2024.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tropical cyclones were responsible for many of the highest-impact events of 2024. These included Typhoon Yagi in Viet Nam, the Philippines and southern China.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the United States, Hurricanes Helene and Milton in October both made landfall on the west coast of Florida as major hurricanes, with economic losses of tens of billions of dollars. Over 200 deaths were associated with the exceptional rainfall and flooding from Helene, the most in a mainland United States hurricane since Katrina in 2005.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tropical Cyclone Chido caused casualties and economic losses in the French Indian Ocean Island of Mayotte, Mozambique and Malawi.
