REDUCED CO2 UPTAKE BY NATURAL SINKS<\/strong><\/p>\n Historically, carbon sinks have played a crucial role in maintaining the Earth\u2019s carbon cycle. That is because they absorb more carbon dioxide (CO2) from the atmosphere than they release. Forests and oceans are some of the most significant natural carbon sinks. Put together, all of the planet\u2019s natural sinks remove about half of all human emissions.<\/p>\n However, in recent years, the amount of CO2 absorbed by these natural sinks has been decreasing. For instance, scientists estimated that the land carbon sink \u2014 a category including forest, plants and soil \u2014 absorbed almost no CO2 in 2023. This happened due to the rise in droughts and wildfires.<\/p>\n The dip in the amount of CO2 absorption by natural sinks means that higher levels of the GHG will remain in the atmosphere, which could accelerate global warming rapidly. Studies have shown that CO2 has contributed more than any other GHG to climate change. In fact, CO2 is responsible for about 70% of global warming, according to an analysis by Facts on Climate Change, a Czech Republic-based independent think tank.<\/p>\n REDUCED COOLING FROM AEROSOLS<\/strong><\/p>\n The past few years have also witnessed a reduction in aerosol emissions, which has made the planet warmer. This is ironic, as a decrease in aerosol levels reduces air pollution. Aerosols are tiny solid and liquid particles suspended in the atmosphere, which are produced mainly by burning fossil fuels.<\/p>\n Story continues below this ad<\/p>\n Although they consist of air pollutants, aerosols reflect incoming sunlight, resulting in less absorption of solar radiation by the Earth\u2019s surface. They also help in the formation of clouds, which impact how much sunlight is reflected or absorbed.<\/p>\n With the world curbing its aerosol emissions, their cooling effect has drastically reduced. For example, in 2020, the International Maritime Organization introduced strict limits on the sulphur content of marine fuels. While this reduced sulfur dioxide (SO2) emissions, the move has already warmed the planet by an estimated 0.04 degrees Celsius.<\/p>\n A 2025 study, published in the journal Communications Earth & Environment, revealed that lower aerosol emissions from East Asia since 2010 have led to a warming of between 0.07 degrees Celsius and 0.05 degrees Celsius.<\/p>\n STRONG EL NI\u00d1O & WEAK LA NI\u00d1A<\/strong><\/p>\n The year 2022 saw the onset of El Ni\u00f1o after seven years. It is a phase of what is known as the El Ni\u00f1o Southern Oscillation (ENSO), a climate phenomenon characterised by changes in sea temperatures along the central and eastern tropical Pacific Ocean, accompanied by fluctuations in the atmosphere overhead.<\/p>\n Story continues below this ad<\/p>\n ENSO influences, alters, and interferes with global atmospheric circulation, which, in turn, influences the weather worldwide. It has three phases \u2013 warm (El Ni\u00f1o), cool (La Ni\u00f1a), and neutral \u2014 which occur in irregular cycles of two to seven years.<\/p>\n The years 2023 and 2024 experienced a strong El Ni\u00f1o event, which contributed to extremely warm temperatures. While the previous year saw the end of the El Ni\u00f1o event, the La Ni\u00f1a event, which was supposed to cool the temperatures, remained quite weak after it emerged. As a result, the anticipated cooling effect was relatively modest, at best.<\/p>\n EXCEPTIONALLY HIGH OCEAN TEMPERATURES<\/strong><\/p>\n The past three years also witnessed unusually warm sea surface temperatures (SSTs) \u2014 the temperature of the water at the ocean surface. One reason for this is that the ocean has absorbed 90% of the extra heat trapped by the GHGs over the past century, causing ocean temperatures to rise.<\/p>\n Story continues below this ad<\/p>\n The situation was exacerbated with the onset of the El Ni\u00f1o in 2022. However, even after the event ended in 2024, the SSTs remained exceptionally high throughout 2025. That\u2019s why, apart from the El Ni\u00f1o, \u201ca significant fraction of the additional warmth of the atmosphere in the last three years has been shown to originate from SSTs across oceanic regions other than the tropical Pacific,\u201d said the Copernicus report.<\/p>\n","protected":false},"excerpt":{"rendered":"The year 2025 was the third-warmest year on record, according to a new analysis by the Copernicus Climate…\n","protected":false},"author":2,"featured_media":711841,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3843],"tags":[213207,213214,96398,213211,728,42805,213208,213209,213215,8152,213212,213213,213210,70,16,15],"class_list":{"0":"post-711840","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-environment","8":"tag-2025-climate-report","9":"tag-climate-change-analysis","10":"tag-copernicus-climate-change-service","11":"tag-el-nino-effects","12":"tag-environment","13":"tag-express-explained","14":"tag-global-warming-data","15":"tag-greenhouse-gases-impact","16":"tag-heat-trapping-greenhouse-gases","17":"tag-indian-express","18":"tag-ocean-temperature-rise","19":"tag-paris-agreement-compliance","20":"tag-record-high-temperatures","21":"tag-science","22":"tag-uk","23":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115935730962652770","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/711840","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=711840"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/711840\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/711841"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=711840"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=711840"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=711840"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
