The last seven years have been the seven warmest on record for the planet, new data shows, as Earth\u2019s temperature continues its precarious climb due to heat-trapping fossil fuel emissions.<\/p>\n\n\n\n
A new analysis by the European Union\u2019s Copernicus Climate Change Service, which tracks global temperature and other climate indicators, found 2021 was the fifth-warmest year on record.<\/p>\n\n\n\n
Though the long-term trend is up, yearly fluctuations in global temperature are expected, mainly because of large-scale weather and ocean patterns like El Ni\u00f1o and La Ni\u00f1a, the latter of which was present in 2021<\/a> and tends to lead to cooler global temperature.<\/p>\n\n\n\n \u201cThe really important thing is to not get hung up on the ranking of one particular year but rather kind of see the bigger picture of ever-warming temperatures, and that ever-warming doesn\u2019t mean every year will be warmer than the next,\u201d said Freja Vamborg, senior scientist at Copernicus. \u201cBut that was what we\u2019ve seen so far with every decade warmer than the next \u2014 and this is quite likely to continue.\u201d<\/p>\n\n\n\n Earth\u2019s average temperature is around 1.1 degrees Celsius above average pre-industrial levels, Copernicus reports, 73% of the way to the 1.5-degree threshold scientists warn the planet must stay under to avoid the worst impacts.<\/p>\n\n\n\n Kim Cobb, director of the Global Change Program at the Georgia Institute of Technology, said a warming of 1.1 degrees Celsius is a \u201cconservative\u201d estimate.<\/p>\n\n\n\n \u201cIt is very fair to say that 1.1 degrees Celsius is conservative, because the last half of the last decade has been warmer than the first half,\u201d Cobb, who is not involved with the report, told CNN.<\/p>\n\n\n\n Even at 1.1 degrees, 2021 made abundantly clear the world is already feeling unprecedented effects of the climate crisis many are not prepared for, including significant melting events in the Arctic<\/a>, deadly floods<\/a>, unprecedented heat waves<\/a> and historic droughts<\/a>. Copernicus also found global greenhouse gas concentrations \u2014 the root cause of the climate crisis and its worsening disasters \u2014 continued to surge.<\/p>\n\n\n\n In 2015, world leaders agreed to heed scientists\u2019 warnings and limit Earth\u2019s rapid temperature rise to below 2 degrees Celsius above pre-industrial levels, with a preferred goal of 1.5 degrees.<\/p>\n\n\n\n That threshold may not sound like much, but NASA scientists say<\/a> it\u2019s similar to how a 1 or 2 degree increase in body temperature can lead to a fever. With every fraction of a degree of warming, the illness worsens with increasing likelihood of needing hospitalization.<\/p>\n\n\n\n For the planet, scientists are tracking Earth\u2019s temperature increase from the baseline at the start of the Industrial Revolution in the mid-to-late 19th century, when humans ramped up the burning of fossil fuels like coal and oil.<\/p>\n\n\n\n Cobb said for every increment of future warming, the latest climate research outlines cascading consequences that would threaten every aspect and necessity on Earth including biodiversity, freshwater, and food supplies.<\/p>\n\n\n\n \u201cWe\u2019ve just barely crossed the 1 degree threshold for warming, and yet we are reeling from a near-constant series of weather and climate extremes,\u201d Cobb told CNN. \u201cWith rare exceptions, these extremes can now be definitively linked to human-caused warming. Going forward, we should expect the frequency and severity of such extremes to increase, exacting an enormous toll on societies around the world.\u201d<\/p>\n\n\n\n 2021 brought heat waves and floods that became mass-casualty events<\/a>; rain fell at the summit of Greenland for the first time ever<\/a> on record; and a historic drought plagued much of the Western U.S. and triggered large, destructive wildfires and never-before-seen water shortages<\/a>.<\/p>\n\n\n\n Almost every corner <\/a>of the world felt the effects of the rapidly warming planet. Copernicus researchers pointed to several regions that saw the most above average temperatures in 2021, spanning the Western U.S. and Canada to Greenland, as well as large swaths of central and northern Africa and the Middle East.<\/p>\n\n\n\n Summer in Europe last year was the warmest on record, the agency reported, with several extreme weather events wreaking havoc across the continent, including the deadly floods in Germany<\/a>, Belgium and the Netherlands as well as the intense wildfires<\/a> in the eastern and central Mediterranean.<\/p>\n","protected":false},"excerpt":{"rendered":" The last seven years have been the seven warmest on record for the planet, new data shows, as Earth\u2019s temperature continues its precarious climb due to heat-trapping fossil fuel emissions.
