The trend has given rise to a puzzle: Are hidden climate change dynamics behind the sudden shift?<\/p>\n<p class=\"\">Last year was the <a href=\"https:\/\/www.nbcnews.com\/science\/science-news\/earth-just-hottest-year-ever-recorded-far-rcna133018\" target=\"_blank\" rel=\"noopener\">hottest in recorded history<\/a>, and through summer, <a href=\"https:\/\/www.nasa.gov\/earth\/nasa-finds-summer-2024-hottest-to-date\/#:~:text=New%20assessment%20of%20temperature%20record,-The%20summer%20record&amp;text=The%20white%20lines%20show%20monthly,the%20record%20set%20in%202023.\" target=\"_blank\" rel=\"noopener\">2024 was on pace to be hotter<\/a>. Even after factoring in the expected effects of greenhouse gas pollution and El Ni\u00f1o \u2014 a natural pattern that typically boosts temperatures \u2014 researchers couldn\u2019t account for roughly 0.2 degrees Celsius (0.36 degrees Fahrenheit) of the warming observed in 2023.<\/p>\n<p class=\"\">A new study offers a possible explanation: Cloud cover has decreased over the past two years, it found, allowing more light to reach and heat the Earth\u2019s surface, rather than being reflected back to space.\u00a0<\/p>\n<p class=\"\">The research, <a href=\"http:\/\/www.science.org\/doi\/10.1126\/science.adq7280\" target=\"_blank\" rel=\"noopener\">published Thursday in the journal Science<\/a>, suggests that an overall decline in the planet\u2019s albedo, as that dynamic is called, is a likely cause of the temperature anomaly observed in 2023.<\/p>\n<p class=\"\">\u201cThis pretty much fits this most recent additional increase of observed solar radiation,\u201d said Helge Goessling, an author of the study and a climate physicist at the Alfred Wegener Institute in Germany.<\/p>\n<p class=\"\">The expected behavior of clouds in a warmer world has been one of the toughest aspects of the climate system to study and model. Answering questions about it will help scientists better determine how sensitive the planet is to greenhouse gas emissions.\u00a0<\/p>\n<p class=\"\">If the reductions in low cloud cover aren\u2019t a result of chance, it likely means Earth is warming even faster than scientists thought.\u00a0<\/p>\n<p class=\"\">\u201cIt\u2019s not really clear yet to what extent some of this might be variability that goes away again,\u201d Goessling said. \u201cIt shifts the odds towards a higher-than-to-be-expected warming.\u201d<\/p>\n<p class=\"\">The new research is based on an analysis of climate models and NASA satellite data about the Earth\u2019s reflectivity. It outlines three possible reasons why fewer low clouds are developing, but doesn\u2019t offer conclusions about how much each factor is contributing.<\/p>\n<p class=\"\">One option is that a natural process is temporarily diverging from normal, causing a reduction in cloud cover. It\u2019s possible, for example, that natural variability is causing the ocean\u2019s surface to warm more than expected, and that is shifting the physics of how clouds form.\u00a0<\/p>\n<p class=\"\">A second possibility is changes to maritime shipping regulations: The International Maritime Organization in 2020 imposed limits on the sulphur content allowed in maritime fuels. Some scientists think that reducing the number of sulphur particles that pollute the atmosphere could have the unintended effect of dampening marine cloud formation.\u00a0<\/p>\n<p class=\"\">\u201cBecause these act as condensation nuclei for clouds, they can make clouds brighter and also more long-lived,\u201d Goessling said of the sulphur particles.<\/p>\n<p class=\"\">The third option is that unidentified feedback loops in the climate system are causing clouds to decrease because of global warming.\u00a0<\/p>\n<p class=\"\">If the latter two possibilities turn out to be primary contributors, that would mean the climate is more sensitive to human pollution than many scientists had thought \u2014 and, therefore, that humanity is closer to exceeding the targets world leaders set for limiting emissions than previously realized. (The term \u201cclimate sensitivity\u201d refers to how warm the planet would be <a href=\"https:\/\/climate.mit.edu\/explainers\/climate-sensitivity#:~:text=Climate%20sensitivity%20is%20a%20term,gases%20in%20the%20atmosphere%20doubles.\" target=\"_blank\" rel=\"noopener\">if the concentration of carbon dioxide and other greenhouse gases in the atmosphere doubled<\/a>.)\u00a0<\/p>\n<p class=\"\">Still, many questions remain, said Zeke Hausfather, the climate research lead at the finance company Stripe and a research scientist at Berkeley Earth.\u00a0\u00a0<\/p>\n<p class=\"\">\u201cWe still do not know for sure that these changes in cloud behavior are not due to short-term variability \u2014 which would return to more normal conditions with time \u2014 or if they represent a new ongoing change to the climate system,\u201d he said in an email.<\/p>\n<p class=\"\">According to the National Oceanic and Atmospheric Administration, average land and ocean surface temperatures in 2023 <a href=\"https:\/\/www.nbcnews.com\/science\/environment\/noaa-terrible-horrible-no-good-hot-year-rcna132959\" target=\"_blank\" rel=\"noopener\">were about 2.12 degrees Fahrenheit above 20th-century averages<\/a>.\u00a0<\/p>\n<p class=\"endmark\">World leaders\u2019 efforts to reduce greenhouse gas emissions remain insufficient. Global temperatures are on pace to rise more than 3 degrees Celsius (5.4 degrees Fahrenheit) on average \u2014 well above the goal of 1.5 degrees Celsius (2.7 degrees Fahrenheit) set in the Paris Agreement.<\/p>\n<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.nbcnews.com\/science\/climate-change\/why-hot-high-temperatures-cloud-cover-decreased-rcna182937\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Summary Global temperatures in the last two years have been even higher than climate scientists expected.
