New data shows the world is still losing the fight against warming. The gases that heat our planet are at record highs. Scientists say countries promised to cut these gases in 2015. But today the world still fails to reduce emissions enough. We need much bigger cuts to keep Earth safe.
A big report from the United Nations shows some progress since 2015. However, this progress is not enough. Current national promises are not enough. Earth could warm by 2.5 to 2.9 degrees this century. That is much higher than the limit scientists say is safe. We must do far more to stop this dangerous warming.
