The atmospheric burden of CO 2 is now comparable to where it was during the Mid-Pliocene Warm Period around 3.6 million years ago, when concentrations of carbon dioxide ranged from about 380 to 450 parts per million. During that time sea level was about 78 feet higher than today, the average temperature was 7 degrees Fahrenheit higher than in pre-industrial times, and studies indicate large forests occupied areas of the Arctic that are now tundra. Since 2000, the global CO2 average has grown by 43.5 ppm, an increase of 12 percent. Without the economic slowdown, the 2020 increase would have been the highest on record, according to Pieter Tans, senior scientist at NOAA’s Global Monitoring Laboratory. The economic recession was estimated to have reduced carbon emissions by about 7 percent during 2020. Economic slowdown prevented a record increase in CO 2 The annual mean at NOAA’s Mauna Loa Observatory in Hawaii was 414.4 ppm during 2020. The global rate of increase was the fifth-highest in NOAA’s 63-year record, following 1987, 1998, 20. The global surface average for carbon dioxide (CO 2), calculated from measurements collected at NOAA’s remote sampling locations, was 412.5 parts per million (ppm) in 2020, rising by 2.6 ppm during the year. Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today. 12.Carbon dioxide levels are now higher than at anytime in the past 3.6 million years "People living in poorer countries, who are often least responsible for greenhouse gas emissions, are bearing the brunt of the health impacts," said Georgiana Gordon-Strachan, an epidemiology professor at the University of the West Indies and director of the Lancet Countdown's regional centre for small island developing states.įunding to help developing countries adapt to climate change and cope with extreme weather events like floods, heat waves and storms, are expected to figure prominently at the upcoming United Nations climate talks, known as COP28, which takes place in Dubai, U.A.E., from Nov. More frequent heat waves could lead to around 525 million more people experiencing food insecurity by 2041-2060, exacerbating the global risk of malnutrition. Abigael Lukhwaro, advocacy manager for Doctors Without Borders in Somalia There is no time to improve the situation and the livelihoods of the populations that we serve. Under this scenario, yearly heat-related deaths are projected to increase 370 per cent by mid-century, with heat exposure expected to increase the hours of potential labour lost globally by 50 per cent. United Nations Secretary General António Guterres is escorted by staff as he visits a camp for displaced persons in Baidoa, Somalia, last April. New projections outline the rapidly growing risks to population health if the target of limiting warming to 1.5 degrees Celsius above pre-industrial levels is missed, with every health hazard monitored by the researchers predicted to worsen if temperatures rise by two degrees by the end of the century. Poorer countries harder hitįor the first time, this year's report used scientific data to quantify what could lie ahead in a heating world. The Lancet Countdown report, produced annually, is led by University College London in collaboration with more than 100 experts from 52 research institutions. She added, "These impacts that we are seeing today could be just an early symptom of a very dangerous future unless we tackle climate change urgently." The impacts are happening here and now," Marina Romanello, executive director of the Lancet Countdown at University College London, said in a briefing prior to the report's release. "We're already seeing climate change claiming lives and livelihoods in every part of the world. We want to know what questions you have about COP 28. World leaders will meet at the annual climate conference in Dubai this month.The report, published Tuesday evening in the prestigious medical journal The Lancet, projected heat-related deaths and food insecurity will skyrocket by mid-century - particularly in the developing world. Climate change is increasingly impacting the health and survival of people worldwide, and projections show risks will quickly rise with further inaction, scientists warn in a new report.
