Global warming will affect the planet sooner than we thought, and we need to act now to prevent irreversible damage.
- In 2015, 196 countries got together to talk about climate change. The members of this United Nations committee then made a pledge to improve the environment, they adopted the Paris Agreement, or Paris Climate Accord. The long-term goal is to keep the increase in global temperature (from about 1900, or the preindustrial period, to now) to 2° Celsius (or 3.6 degrees Fahrenheit, which is the scale most Americans use).
- The earth has already increased its temperature 1 degree since the preindustrial period.
- The committee hired a group of scientists to answer the question: what would happen to the earth if we had (just) a 1.5 degree change?
- 91 scientists from 42 countries reviewed 6000 studies over about a year and a half and found that the difference between a 1.5 degree change and a 2 degree change wasn’t all that significant. That, even a 1.5 degree change would create similar outcomes (to the 2 degree change): risks to fisheries, rising sea levels, high impact storms, crop loss, droughts, food shortage, coastal flooding among them. And, the 1.5 degree change will probably occur by 2030-2050
- In order to change the trajectory, they said, we’ll need much more effective and thorough green energy practices.
