A temporary cooling La Nia event early in the year means that 2021 is expected to be only the fifth to seventh warmest year on record. Law Dome, Antarctica: approximately 1008 CE to 1980 CE Preliminary rapid attribution studies have been carried out for the heatwave in northwest America in June and July and of floods in western Europe in July. This is because the concentrations of different halogenated gases can vary by a few orders of magnitude. The State of the Climate in Africa 2019 report, The global averages for ozone only cover the area between 50N and 50S latitude (77 percent of the Earths surface), because at higher latitudes the lack of sunlight in winter creates data gaps and the angle of incoming sunlight during the rest of the year reduces the accuracy of the satellite measuring technique. Monthly mean carbon dioxide concentrations for Barrow, Alaska; Cape Matatula, American Samoa; and the South Pole. The IPCCs Sixth Assessment report, published in 2021, found that human emissions of heat-trapping gases have already warmed the climate by nearly 2 degrees Fahrenheit (1.1 degrees Celsius) since pre-Industrial times (starting in 1750). It highlights impacts on food security and population displacement, harming crucial ecosystems and undermining progress towards the Sustainable Development Goals. A preliminary analysis based on seven global data sets suggests that 2020 exceeded that record. Read on for the answers.
