Global warming, caused by the increase in greenhouse gas emissions, leads to climate change, which has a range of effects on the environment and society. Some of the changes to the climate that global warming causes include:

• Increased temperatures: The world is now warming faster than ever before, and the global average temperature has reached 1.1°C above pre-industrial levels. This warming leads to more heatwaves, droughts, and wildfires.

• Melting ice: As temperatures rise, glaciers and ice sheets are shrinking, and sea ice is breaking up earlier. This melting leads to rising sea levels, which can cause flooding and erosion.

• Changes in precipitation: Climate change can cause changes in precipitation patterns, leading to more frequent and severe floods and droughts.

• Shifts in ecosystems: Climate change can cause shifts in the geographic ranges of plants and animals, and can lead to the extinction of some species.

• Ocean acidification: As the oceans absorb more carbon dioxide, they become more acidic, which can harm marine life and ecosystems.

• Increased frequency and severity of extreme weather events: Climate change can cause more frequent and severe hurricanes, cyclones, and typhoons.

The severity of these effects depends on the total amount of carbon dioxide emitted, and reducing emissions can help avoid some of the worst effects.
