The U.N. climate panel has released its most comprehensive assessment yet and the future looks very very bleak.
The Intergovernmental Panel on Climate Change (IPCC) has point blank said that humans are causing climate change, with the first line of its report summary reading: "It is unequivocal that human influence has warmed the atmosphere, ocean and land."
The report adds, that even with the severest of cuts, countries will not be able to prevent global warming of 1.5 degrees Celsius above pre-industrial temperatures.
Weather extremes once considered rare or unprecedented are becoming more common -- a trend that will continue even if the world limits global warming to 1.5C.
Severe heat waves that happened only once every 50 years are now happening roughly once a decade. Tropical cyclones are getting stronger. Most land areas are seeing more rain or snow fall in a year. Severe droughts are happening 1.7 times as often. And wildfires will get longer and more intense.
Summertime sea ice atop the Arctic Ocean will vanish entirely at least once by 2050, under the IPCC's most optimistic scenario. The region is the fastest-warming area of the globe - warming at least twice as fast as the global average.
Sea levels are sure to keep rising for hundreds or thousands of years. Even if global warming were halted at 1.5C, the average sea level would still rise about 2 to 3 meters (6 to 10 feet), and maybe more.
The UN has said that the report is a reality check and provides world leaders with a summary of the climate change crisis ahead of COP26, in early November.
U.N. Secretary-General, António Guterres has said, that the report is a code red for humanity, adding that alarm bells are deafening, and the evidence is irrefutable.
