Earth and climate scientists generally agree that humans are contributing to global warming, but there are naysayers.

Apart from the science, the public discussion is informative but not necessarily objective.

"CO2 traps heat -- more CO2 means a warmer climate. That is basic physics, borne out by the history of climate. Denying these well-established facts is about as smart as claiming the Earth is flat, and best left to cranks, ideologues and fossil fuel lobbyists." ~ Stefan Rahmstorf, professor of ocean physics at Germany's Potsdam Institute for Climate Impact Research. That's one side of the debate, of course.

I hope Trump listens to his daughter Ivanka on climate change, Mike ... CNBC-1 hour ago - The former New York mayor says he wants President Trump to change his mind about pulling out of the Paris agreement. "We are two-thirds of ...

(CNN) Until last Friday night, the eve of the People's Climate March on Washington, the US government website EPA.gov explained how humans are warming the planet by burning fossil fuels and why that is important for us and for future generations. Now the page carries an Orwellian message: "This page is being updated."

"Thank you for your interest in this topic," the message continues. "We are currently updating our website to reflect EPA's priorities under the leadership of President Trump and [EPA] Administrator Pruitt."

It's been clear for some time what Donald Trump and his appointees prefer to think of climate change. At worst, they call it a hoax. At best, they say it's overblown -- no big deal. We need more science, they insist, while stripping government science agencies of funding.

Based on research spanning more than half a century, scientists understand that human contribution is the single critical change factor. Regular reviews of actively publishing climate scientists (Ref) reveal that the majority agree: climate-warming trends over the past century are most likely due to human activities. Many scientific organizations worldwide have independently issued public statements endorsing this position. That said, there are a minority who disagree and who should be heard objectively. Beyond the science, biased contrarians suggest global warming ended about 19 years ago (despite the 10 warmest years on record occurring in that period) and that any further warming is unlikely to be a critical concern. (Ref) The disagreement is much politicised, unfortunately, rather than debated reasonably.

The administration's position is troubling, and not only because their policies may contribute to human-induced global warming with perhaps worsening droughts and rising seas. It is troubling because Trump and this administration are apparently "gaslighting" the public on the science to date.

With the same playbook the tobacco industry used, Trump and other political deniers inject uncertainty and confusion into climate policy discussions. Without addressing the science, they discount it as inconsequential. You can do that when you're powerful; you can insert your preferred truth without factual backing.

Gaslighting. Why might anyone do that? Why might a group of power players do that?

Here's one reason to consider ... Exxon knew about fossil fuel and climate change 40 years ago. They did their own research, then covered the results with a multi-million dollar obfuscation campaign, much like the tobacco industry's strategy.

Is there relevant opinion on both sides of the issue, and is the corporate/political arena the appropriate venue? In science, what is relevant is independently reproducible results.

Among papers expressing a position on AGW, an overwhelming percentage (97.2% based on self-ratings, 97.1% based on abstract ratings) endorses the scientific consensus on AGW.”
