How a Few Small Fixes Could Stop Climate Change

When thinking about new ways to tackle climate change, University of Oxford researcher Thom Wetzer first points out how a modest rise in temperature could push the Earth to a tipping point that yields dramatic climate change. A little warming, for example, could cause Arctic permafrost to melt, unleashing enough heat-trapping methane to cook the planet.

Wetzer and his colleagues turned the idea of a tipping point on its head, theorizing that small changes in policy or the development of a new technology, for instance, could lead to big, positive changes in the way we produce and consume energy. Their proposal is outlined in a paper in the journal Science.

“Climate change brings risks that will, in one way or another, impact most people’s lives — and certainly the generations that follow,” said Wetzer, a co-author. “Whether that is through extreme weather events, changes in the economy or the reactions of politicians to these climate risks. We can either put up with these risks and watch them grow out of control, or we can act to mitigate the worst impacts of climate change.”

Climate Feedback Review...

Breitbart article baselessly claims a study of past climate invalidates human-caused climate change

Climate Feedback 16

 

Analysis of the article, Scientists Prove Man-Made Global Warming Is a Hoax by John Nolte, Breitbart, Apr 6, 2019

Ten scientists analyzed the article and estimated its overall scientific credibility to be ‘very low’

A majority of reviewers tagged the article as: Flawed reasoningInaccurateMisleading.

Review Summary

This Breitbart article comments on a story by ThinkProgress about a study related to past climate, mistakenly concluding that it invalidates the science that shows human activities are currently altering the climate of our planet.

Scientists who reviewed the article explain that it builds on a fallacious reasoning, as if the fact that climate has changed due to natural forcing in the past would make it impossible for human emissions of CO2 to change it now. In reality, the climate of the Earth can be influenced by various forcings, including changes in the Sun’s irradiance and atmospheric concentrations of greenhouse gases, which in turn can be due to natural causes (as has been the case in the past) or activities related to human actions—as is the case currently.

All the scientists indicated that the content of the article does not support the claim made by the headline.
