The provisional report is accompaniedby an interactive maphighlighting information provided by Members on the extreme events they faced from January to August. As a result, the Arctic-wide sea-ice extent was record low in the first half of July. UN Climate Change News, 27 October 2020 Increasing temperatures and sea levels, changing precipitation patterns and more extreme weather are threatening human health and safety, food and water security and socio-economic development in Africa, according to a new report devoted exclusively to the continent. Just in the last 800,000 years, there have been eight cycles of ice ages and warmer periods, with the end of the last ice age about 11,700 years ago marking the beginning of the modern climate era and of human civilization. The Government has until 31 December 2021 to set the first three emissions budgets out to 2035 and release the countrys first emissions reduction plan detailing the policies it will use to achieve the budgets. This graph shows the rising level of carbon dioxide in our atmosphere since 1960. For carbon dioxide, methane, nitrous oxide, and halogenated gases, recent measurements come from monitoring stations around the world, while measurements of older air come from air bubbles trapped in layers of ice from Antarctica and Greenland. {kTvE!S[GY fZ But temperatures and meltwater runoff were well above normal in August 2021 as a result of a major incursion of warm, humid air in mid-August. Human activity from releasing greenhouse gases and aerosols into the atmosphere, to changing the use of land is the main driver of climate change. Petrenko, J.P. Severinghaus, D. Baggenstos, and R.F.

The data come from a variety of historical ice core studies and recent air monitoring sites around the world. 9. Nitrogen trifluoride global emissions estimated from updated atmospheric measurements. Carbon dioxide, methane, nitrous oxide, and certain manufactured gases called halogenated gases (gases that contain chlorine, fluorine, or bromine) become well mixed throughout the global atmosphere because of their relatively long lifetimes and because of transport by winds. 10. Each line represents a different data source.. Data source: Compilation of five underlying datasets6 This creates a positive feedback loop in which warming leads to more warming. An abnormal spring cold outbreak affected many parts of Europe in early April. In manyparticipatingcountries, it is the first time thatlarge-scalepolling of public opinion haseverbeen conducted on the topic of climate change. Concentrations of many of the halogenated gases shown in Figure 4 were essentially zero a few decades ago but have increased rapidly as they have been incorporated into industrial products and processes. Rainfall was well below average over much of southern Brazil, Paraguay, Uruguay and northern Argentina. WASHINGTON (Sept. 2, 2021) A new EPA analysis released today shows that the most severe harms from climate change fall disproportionately upon underserved communities who are least able to prepare for, and recover from, heat waves, poor air quality, flooding, and other impacts. IPCC (Intergovernmental Panel on Climate Change). Sea-ice extent in the East Greenland Sea was a record low by a large margin. Globally, the amount of ozone in the troposphere increased by about 12percent between 1979 and 2020(see Figure 5). 2017. The past seven years are on track to be the seven warmest on record, according to the provisional WMO State of the Global Climate 2021 report, based on data for the first nine months of 2021.
