UN scientists are starting to warn that the world must act urgently to defuse the looming “climate time bomb”. Otherwise, climate change will unleash environmental impacts and lead to disasters. The final report of the United Nations Intergovernmental Panel on Climate Change (IPCC) states that drastic action must be taken before it is too late.
In this final report, scientists emphasize that “quick, deep and immediate carbon dioxide removal” actions must be taken to reduce global carbon dioxide emissions by 2025 and cut them in half by 2030. Carbon dioxide is a greenhouse gas that is a major cause of climate change caused by humans.
Scientists have warned that exceeding this 1.5 degree Celsius threshold greatly increases the risk of tipping points that could unleash irreversible climate change, such as the collapse of most of the Greenland and West Antarctic ice sheets, extreme heat waves, severe droughts, water stress and extreme weather around the world.
This synthesis report offers insight into the threat posed by climate change and what humanity can do to stop it. They say that even if all the carbon-cutting policies previously promised by governments were fully implemented by 2020, the world would still warm by 3.2 degree Celcius in 2100.
