About a month ago, the United Nations Intergovernmental Panel on Climate Change (or IPCC) released another landmark report saying that, yes, climate change is really happening and we’re already seeing the effects of just one degree Celsius of warming and those effects are bigger than we even thought they were going to be. Droughts are more devastating, hurricanes are more damaging, wildfires are more intense and frequent. We know what this is doing to people and other living things from Yemen to Puerto Rico to Paradise, California.
Because these effects are bigger and happening more quickly than scientists thought they would, the report said we need to keep warming to 1.5 degree Celsius, not the 2 degrees originally agreed upon by world leaders in 2015. This half degree of difference could make a world of difference. It could leave our children with a planet that sort of looks like our own. There will be big environmental challenges and changes with 1.5 degree Celsius warming — there are already with 1 degree. But with 2 degree Celsius, we’re talking more about the end of the world as we know it, especially for the poor and vulnerable. Says Debra Roberts, the co-chair of an IPCC working group: “(1.5 degrees Celsius) is a line in the sand and what it says to our species is that this is the moment and we must act now.”
