Here is more information I wanted to share, with links to additional resources on this topic.
Ninety-seven percent of climate scientists who publish in the field and every major scientific academy in the world agree that climate change is real, is mostly caused by humans, and requires urgent action. The fact that carbon dioxide (CO2) warms the Earth has been known since the 1800s. It is also well known that man has increased the CO2 content in the atmosphere by 40 percent since the industrial revolution by burning gigatons of fossil fuels every year. Arguments such as “it’s the Sun” or “it’s natural variation” have all been debunked in scientific literature. Read more at SkepticalScience.com.
Recent studies show that extremely hot days in summer that happened about 0.25 percent of time 50 years ago are now happening about 10 percent of the time–a 4000 percent increase. The same study concluded that there is a high level of confidence that the recent Texas heat wave, the Russian heat wave the year before that, and the 2003 European heat wave (that killed tens of thousands) were not natural events and were indeed caused by climate change. Even an organization funded by those who deny climate change, the Berkeley Earth Surface Temperature Study, found that the Earth has warmed +0.8°C (+1.4°F) which is consistent with NASA and other scientific organizations’ results.
Speaking of NASA, while a group of retired astronauts, engineers, and administrators did write a letter to NASA, not a single one of the signers has any climate science qualifications.
Part of the confusion among media about climate change stems from a fossil fuel-funded disinformation campaign (which includes some of the same groups that tried to show there was doubt that cigarettes were dangerous). The facts speaks for themselves: Farmers are planting weeks earlier than they used to, 90 percent of mountain glaciers are melting around the world, gravity satellites show that Greenland and Antarctica are losing more than a hundred cubic kilometers of ice ever year. Last year, there were 14 U.S. weather events with $1 billion or more in damage. The previous maximum was nine events and the long-term average is four.
Continuing to deny science will hasten our arrival to a point where there is no turning back. And that point is fast approaching. Even a few degrees increase in average temperature will create a climate spiraling out of control for future generations.
It’s time to accept reality and take steps to protect our children, our grandchildren, and our planet.
