Humans must limit warming to avoid climate tipping points, new study finds

Humans must limit global warming to 1.5 degrees Celsius to avoid runaway ice melting, ocean current disruption and permanent coral reef death, according to new research by an international group of climate scientists.

The new study is the latest and most comprehensive evidence indicating that countries must enact policies to meet the temperature targets set by the 2015 Paris agreement, if humanity hopes to avoid potentially catastrophic sea level rise and other worldwide harms.
