Climate Questions: What's going on with climate change?

Addressing climate change — a now ubiquitous term for the warming of the planet caused by humans emitting carbon dioxide and methane from coal, oil and natural gas into the atmosphere — is becoming exponentially more pressing, with the language of scientists, officials and activists becoming more serious with every passing year.

The most recent report by the world’s top body of climate scientists gave a damning assessment of where the world is headed if more isn't done to curb global warming. Already, more extreme weather events are happening across the globe, from longer, more intense and more frequent droughts and heat waves to devastating floods and wetter hurricanes, attributed at least in part to climate change.

How the planet got here, the current and future effects of climate change, and what to do next, are all questions that experts have been researching for decades.
