GLOBAL WARMING

                

                        GLOBAL WARMING

      In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common.  Amplified warming in the Arctic has contributed to thawing permafrost, retreat of glaciers and sea ice decline.

FUTURE GOBAL WARMING

The World Meteorological Organization estimates a 66% chance of global temperatures exceeding 1.5 °C warming from the preindustrial baseline for at least one year between 2023 and 2027. Because the IPCC uses a 20-year average to define global temperature changes, a single year exceeding 1.5 °C does not break the limit.

Extreme weather: Drought and high temperatures worsened the 2020 bushfires in Australia.

• Global warming boosted the risk of the hot, dry weather that's likely to cause bushfires by at least 30%, they say.
• But the study suggests the figure is likely to be much greater.
• It says that if global temperatures rise by 2C, as seems likely, such conditions would occur at least four times more often.
• The analysis has been carried out by the World Weather Attribution consortium.
