“Good riddance,” Trump declared in response to the admission that the scenario used by the UN’s IPCC to model future climate change was “implausible.”

The Heartland Institute reacts to President Donald Trump’s remark.

Representative Concentration Pathway 8.5 (“RCP 8.5”) is a high-emissions climate scenario used by the United Nations’ (“UN’s”) Intergovernmental Panel on Climate Change (“IPCC”) to model future climate change. It was formally adopted in the IPCC Fifth Assessment Report (AR5) in 2014.

RCP 8.5 has been used by corporate media for years to push unfounded claims of catastrophic global warming due to “emissions” from human activity. However, a recent study has concluded that RCP 8.5’s scenario is “implausible.” The study is notable because it is being used to establish the new scenario framework for the upcoming IPCC Seventh Assessment Report due in 2029.

That RCP 8.5 was b*ll*cks has been known for a long time. But, despite this being pointed out by many –including by believersin anthropogenic climate change alarmism – the misinformation and disinformation propagated by corporate media and others continued.

On hearing the “implausible” admission, US President Donald Trump said, “Good riddance!” A comment which corporate media and “fact checkers” have been busy debunking and demonising him for. In the following, The Heartland Institute gives its reaction to President Trump’s remark.

This is a great victory for Climate Realism, as realists like those writing herehave long explainedthat RCP 8.5 is unrealistic, likely impossible, and used exclusively to generate terrifying headlines. It will not be missed.
