Researchers have released three additional studies confirming the consensus among scientists that climate change is real. More than 99 percent of scientists have reached the same conclusion that global warming is real and caused by human activity, with findings showing that current warming is unprecedented when compared to the last 2,000 years.

Even though most deniers are political or corporate-backed — rather than driven by science — scientists continue to release worrisome research repeating and reconfirming that all evidence indicates climate change is real in hopes that the consensus itself will be convincing.

“There is no doubt left — as has been shown extensively in many other studies addressing many different aspects of the climate system using different methods and data sets,” said Stefan Brönnimann of the University of Bern.

The three studies were published in Nature and Nature Geoscience and indicate that the temperature spikes over the last few decades have not been as dramatic over the last 2,000 years. While there have been other roving and site-specific temperature changes, such as the Little Ice Age, the current record-breaking temperatures impact the entire globe. The researchers used proxy indicators such as evidence in trees, ice and sediment, which show that changes in climate have never been as severe as they are now.

“The good news is public understanding of the scientific consensus is increasing,” said researcher James Cook, who wrote the original paper on scientific consensus in 2013. “The bad news is there is still a lot of work to do yet as climate deniers continue to persistently attack the scientific consensus.” Last week, the original paper was downloaded for the one millionth time, making it the most-read study by the Institute of Physics. Cook also wrote a follow-up to this study, but because of the recent rise in disasters and interest in climate change, he plans to revise his paper again.
