The evidence is clear: the main cause of climate change is burning fossil fuels such as oil, gas, and coal. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up.Speak up! ...

We're perhaps between 50 and 60 years too late to prevent catastrophic climate change simply by ceasing emissions, scientists say.
Yes. While we cannot stop global warming overnight, or even over the next several decades, we can slow the rate and limit the amount of global warming by reducing human emissions of heat-trapping gases and soot (“black carbon”). ... Once this excess heat radiated out to space, Earth's temperature would stabilize.Increases in pests and diseases and more frequent and intense droughts and floods, reduce the availability of food. Heat-stress causes poor yields, or worse, crop failures. Reducing short-lived climate pollutants gives us our best chance to rapidly limit global temperature rise and reduce the risks to food security.
