The report devotes an extensive section to weather and climate impacts on human health, food security, migration, ecosystems and marine life.

This poses a threat to crop yields and, combined with population increase, will mean considerable food security challenges for vulnerable countries in the future,” he said. “One of the main impacts of climate change is more erratic rainfall patterns. Wildfires swept through the Arctic and Australia,” said Mr Taalas. Countries ranging from the Bahamas to Japan to Mozambique suffered the effect of devastating tropical cyclones. Heatwaves and floods which used to be “once in a century” events are becoming more regular occurrences.

And, once again in 2019, weather and climate related risks hit hard. “On a day-to-day basis, the impacts of climate change play out through extreme and “abnormal” weather. “We are nowhere near on track to meet the Paris Agreement target.” “If we do not take urgent climate action now, then we are heading for a temperature increase of more than 3☌ by the end of the century, with ever more harmful impacts on human wellbeing,” said WMO Secretary-General Petteri Taalas. In Antarctica, 2019 saw record low ice extents in some months. The daily Arctic sea-ice extent minimum in September 2019 was the second lowest in the satellite record and October has seen further record low extents. Vital marine ecosystems are being degraded. Sea water is 26 percent more acidic than at the start of the industrial era. Ocean heat is at record levels and there have been widespread marine heatwaves. The ocean, which acts as a buffer by absorbing heat and carbon dioxide, is paying a heavy price. Sea level rise has accelerated since the start of satellite measurements in 1993 because of the melting of ice sheets in Greenland and Antarctica, according to the report. CO 2 lasts in the atmosphere for centuries and the ocean for even longer, thus locking in climate change. The WMO provisional statement on the State of the Global Climate, says that the global average temperature in 2019 (January to October) was about 1.1 degrees Celsius above the pre-industrial period.Ĭoncentrations of carbon dioxide in the atmosphere hit a record level of 407.8 parts per million in 2018 and continued to rise in 2019. 2019 is on course to be the second or third warmest year on record, according to the World Meteorological Organization. Average temperatures for the five-year (2015-2019) and ten-year (2010-2019) periods are almost certain to be the highest on record. Madrid, 3 December 2019 - The year 2019 concludes a decade of exceptional global heat, retreating ice and record sea levels driven by greenhouse gases from human activities.
