While scientists and environmentalists debate when global warming may turn Earth into a “hothouse,” conservatives and other experts were skeptical of renewed warnings of a “tipping point.”

Why? Because scientists warning of “hothouse Earth” veered from presenting a scientific case (a dubious one) for alarmism into political activism.

The “hothouse Earth” paper that’s made waves in the media calls for a “deep transformation based on a fundamental reorientation of human values, equity, behavior, institutions, economies, and technologies.” Many conservatives took that to mean global government and socialism.

Bloomberg New Energy Finance co-founder Michael Liebreich, who’s not a skeptic of man-made warming, called the paper “a crock,” adding “as a conservative I can’t be bothered to read it.” (RELATED: Scientists Issue ‘Absurd’ Doomsday Prediction, Warn Of ‘Hothouse Earth’)

What a crock! Instead of focusing on the science and identifying tipping points and trajectories, the abstract meanders off to demand global government. Mixing science with socialist demands usually means the science is crap, and as a conservative I can’t be bothered to read it. — Michael Liebreich (@MLiebreich) August 8, 2018

When challenged, Liebrich doubled down, quoting directly from the paper that called for “collective human action” on global warming.

“Collective human action is required… Such action entails stewardship of the entire Earth System – biosphere, climate, and societies…” Can’t get a much clearer demand for global government than that. — Michael Liebreich (@MLiebreich) August 9, 2018

The paper Liebrich is referring to was published Monday in the Proceedings of the National Academy of Sciences. A group of scientists warned of a global warming tipping point at 2 degrees Celsius — the goal of the Paris agreement. The authors call for “fundamental societal changes” to human society while generating alarming media headlines.

Even liberal environmental writer Eric Holthaus tweeted the “hothouse” paper had “some @DemSocialists shit,” referring to the Democratic Socialist of America political party.

The Global Warming Policy Forum, the political arm of a U.K.-based think tank co-founded by former conservative Member of Parliament Nigel Lawson, blasted the “socialist agenda of climate alarmism.”

Conservatives weren’t the only ones calling out the “hothouse” paper’s political tinge. Alex Trembath of the ecomodernist Breakthrough Institute noted his skepticism of the paper.

I must admit I get a little skeptical when earth system scientists claim their science shows we need “transformed social values.” https://t.co/eTIZ9J8wBz pic.twitter.com/Af7MigYly2 — Alex Trembath (@atrembath) August 9, 2018

University of Colorado professor Roger Pielke, Jr. noted the lead authors of the “hothouse Earth” paper put out a similar essay in 2013, calling for an “institution (or institutions) operating, with authority, above the level of individual countries to ensure that the planetary boundaries are respected.”

Planetary boundaries being trotted out again (“hothouse earth”). Never gets old, does it?
