Conspiracy theories abound, especially in the age of fake news. But let’s get one thing straight: climate change is as real as it gets. If nothing had convinced you before, the extreme weather this year has been enough to sway even the most die-hard deniers. According to The Associated Press-NORC Centre, seven out of 10 Americans say they believe climate change is happening. According to the news report, denial is now “softer” and more “subtle.”
In its latest 3,500 page long report released this year, the IPCC said that “Global surface temperature has increased faster since 1970 than in any other 50-year period over at least the last 2,000 years.” It is not just a routine heating phase in the Earth’s natural cycle.
This assessment is based on palaeological analysis of sediment and ice for the period before the Industrial Revolution and on temperature records.
“It is unequivocal that human influence has warmed the atmosphere, ocean and land,” the report concluded.
While dissidents might argue that a little warming might not be so bad given that colder zones could become arable, any benefit will be offset by the melting of permafrost.
Ultimately, ‘consensus’ does confer legitimacy. A recent survey by Cornell University of peer-reviewed studies on climate change found that authors agreed that climate change was caused by humans in more than 99 percent of them.
