From dying coral reefs to fires and coastal flooding, the effects of climate change are already being felt around the world. And it will only get worse.

A 2018 report from climate scientists from around the globe found that some of climate change’s disastrous consequences will be in full force if Earth’s temperature rises past 1.5 degrees--something that could happen as early as 2040 at current emissions rates.

This hour, we ask: besides reducing emissions, does the world need to look at ways to take carbon out of the atmosphere? From forests to machines that suck carbon out of the air, we learn more about “negative emissions” strategies.

And we also hear about another major climate change concern: the thawing of the permafrost. Researchers say the thawing of this polar ecosystem could be not only a consequence but also cause of worsening carbon emissions.
