Concerningly, the Earth’s average temperature has already increased by appromixately 1.1 above pre industrial levels, according to a 2021 assessment by the IPCC.

Paris Agreement

The Paris Agreement is a legally binding international treaty on climate change, adopted in 2015 was meant to keep the global average temperature “well below 2°C above pre industrial levels and pursuing efforts to limit the temperature increase to 1.5°C”.

Keep Temperatures

In order to keep temperatures below the 1.5°C target, it is deemed necessary to achieve a global Net Zero emissions output by 2050.

Extreme Weather Events

Failure to meet this target will likely lead to an increase in extreme weather events, including record breaking temperatures, and catastrophic droughts and flooding.
