There’s still a way to reach global goal on climate change – Tampa Bay Times

If nations do all that they’ve promised to fight climate change, the world can still meet one of two internationally agreed upon goals for limiting warming. But the planet is blowing past the other threshold that scientists say will protect Earth more, a new study finds.The world is potentially on track to keep global warming at, or a shade below, 2 degrees Celsius (3.6 degrees Fahrenheit) hotter than pre-industrial times, a goal that once seemed out of reach, according to a study published Wednesday in the journal Nature.That will only happen if countries not only fulfill their specific pledged national targets for curbing carbon emissions by 2030, but also come through on more distant promises of reaching net zero carbon emissions by mid-century, the study says.This 2 degree warmer world still represents what scientists characterize as a profoundly disrupted climate with fiercer storms, higher seas, animal and plant extinctions, disappearing coral, melting ice and more people dying from heat, smog and infectious disease. It’s not the goal that world leaders say they really want: 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times. The world will blast past that more prominent and promoted goal unless dramatic new emission cuts are promised and achieved this decade and probably within the next three years, study authors said.Both goals of 1.5-degrees and 2-degrees are part of the 20 …
