Introduction to Climate Change

The world is on track for a catastrophic 2.6C temperature rise by the end of the century, according to recent reports from the UN Environment Programme (UNEP) and the World Meteorological Organization. This is far above the 1.5C limit that would avoid the worst impacts of climate change.

Current Pledges and Emissions

The UNEP report finds that current pledges under the Paris Agreement put the world on track for a 2.5-2.9°C temperature rise above pre-industrial levels this century. The report also finds that none of the G20 countries are reducing emissions at a pace consistent with their net-zero targets.

Consequences of Inaction

If countries do not increase their ambition and start delivering immediately, the world will face debilitating impacts, including more frequent and severe heatwaves, droughts, and storms. The report highlights the need for urgent action to limit global warming and avoid the worst impacts of climate change.

Path Forward

To get on track for 1.5°C, countries need to increase their ambition and start delivering immediately. This includes reducing emissions by 42% by 2030 and 57% by 2035. The report calls for all nations to deliver economy-wide, low-carbon development and to fully implement their Nationally Determined Contributions (NDCs).
