Summary
- Countries have debated how to combat climate change since the early 1990s. These negotiations have produced several important accords, including the Kyoto Protocol and the Paris Agreement.
- Governments generally agree on the science behind climate change but have diverged on who is most responsible, how to track emissions-reduction goals, and whether to compensate harder-hit countries.
- Experts say governments need to move much more quickly to prevent the global average temperature from rising by 1.5°C. When that happens, the world will suffer devastating consequences, such as heat waves and floods.
Introduction
Over the last several decades, governments have collectively pledged to slow global warming. But despite intensified diplomacy, the world is already facing the consequences of climate change, and it is expected to get worse.
Through the Kyoto Protocol and the Paris Agreement, countries agreed to reduce greenhouse gas emissions, but the amount of carbon dioxide in the atmosphere keeps rising, heating the Earth at an alarming rate. Scientists warn that if this warming continues unabated, it could bring environmental catastrophe to much of the world, including staggering sea-level rise, record-breaking droughts and floods, and widespread species loss.
