CLAIM REVIEWS

Claim that CO2 is cooling the planet is misleading, anthropogenic CO2 emissions overall cause global warming

CLAIM
Global warming slowing down? 'Ironic' study finds more CO2 has slightly cooled the planet

SOURCE: Sebastian Kettley, Express

Published: 24 Apr 2020

VERDICT

Human activities have dramatically increased atmospheric CO2 levels, causing imbalances in the global carbon cycle

CLAIM
Human additions of CO2 are in the margin of error of current measurements and the gradual increase in CO2 is mainly from oceans degassing as the planet slowly emerges from the last ice age.

VERDICT

CO2 can increase plant growth in greenhouses while also negatively affecting ecosystems and human societies

CLAIM
CO2 is a plant nutrient...it’s not a pollutant that threatens human civilization. If CO2 was so terrible for the planet, then installing a CO2 generator in a greenhouse would kill the plants.

VERDICT

CO2 emissions from human activities have imbalanced the atmospheric carbon budget, significantly contributing to climate change, contrary to online claim

CLAIM
Less than 5% of carbon dioxide emissions are produced by man [... they] can’t cause 30% of today’s atmospheric carbon dioxide

SOURCE: Editorial Board, Issues & Insights

Published: 11 Feb 2020

VERDICT

It’s true that the current carbon dioxide level is higher than any time in human existence

CLAIM
the concentration of carbon dioxide in Earth’s atmosphere has climbed to a level last seen more than 3 million years ago — before humans even appeared on the rocky ball we call home

VERDICT

Energy Secretary Rick Perry incorrectly claims CO2 is not primary cause of climate change

CLAIM
Most likely the primary control knob [on climate change] is the ocean waters and this environment that we live in.

SOURCE: Rick Perry, CNBC

Published: 20 Jun 2017

VERDICT

CO2 is a greenhouse gas that caused warming during past climate changes, notably as a feedback amplifying other factors

CLAIM
Increases in atmospheric CO2 followed increases in temperature. Therefore, CO2 levels could not have forced temperatures to rise.

VERDICT

In CNN interview, William Happer misleads about the impact of rising carbon dioxide on plant life

CLAIM
there's this myth that's developed around carbon dioxide that it's a pollutant […] Carbon dioxide is a perfectly natural gas, it’s just like water vapor, it’s something that plants love.

SOURCE: William Happer, CNN

VERDICT

Science shows that humans are primarily responsible for climate change, counter to EPA Administrator Scott Pruitt’s claim

CLAIM
I would not agree that [carbon dioxide is] a primary contributor to the global warming that we see.

VERDICT

Wall Street Journal op-ed ignores evidence of negative impacts of increasing CO2

Increased atmospheric carbon dioxide has helped raise global food production and reduce poverty.
