To say that last year was hot is an understatement. It was 1.69 degrees Fahrenheit (0.94 Celsius) warmer than the 20th century average, according to National Oceanic and Atmospheric Administration figures released on Wednesday. That may not sound like much, but on a planetary scale it’s a profound shift that has decimated coral reefs, thawed polar ice at a near-catastrophic rate, and nudged agricultural planting zones across national borders.
Climate scientists don’t place much weight on a single record-hot month, or even a single record-hot year. What sets off alarms, said Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, is the rapid accumulation of warming we’ve been experiencing over many years. Sixteen of the 17 hottest years have come to pass over the past 17 years, and temperatures are rising 10 times faster than during the bounce back from the last ice age.
“The planet is warming and we have a pretty good idea why it is warming,” Schmidt said simply. “It is warming because we are not reducing the amounts of greenhouse gases by the amounts we need to.”
I am not an expert of climate science, yet there is overwhelming consensus in their scientific community that climate change is real and "extremely likely (meaning 95% probability or higher) that this warming is predominantly caused by humans". I believe that most academics are honest people and the vast majority are suggesting that climate change is real:
