CLAIM REVIEWS

Climate scientists agree that human-caused greenhouse gas emissions are primarily responsible for climate change, contrary to claims in Clear Energy Alliance video

CLAIM
The scientific consensus on whether global warming is human caused is not 97 percent, it’s less than 1 percent. There is no way to measure the human impact on climate change.

VERDICT

Low solar activity has little effect on Earth’s climate, contrary to claim in The Sun

CLAIM
"The sun has gone into ‘lockdown’ which could cause freezing weather, earthquakes and famine, say scientists"

VERDICT

The global polar bear population is threatened by loss of sea ice, contrary to PragerU’s video claim

VERDICT

Diesel cars are a major source of NO2 emissions in European cities, contrary to online claim

CLAIM
The drop in NO2 content has only been “slight”. So it cannot be the evil diesel engine cars that are “choking” our cities.

VERDICT

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

Human-induced increases in greenhouse gases are the primary driver of global warming, contrary to claims in CFACT article

CLAIM
They tell us that we are the primary forces controlling earth temperatures by the burning of fossil fuels and releasing their carbon dioxide. I hope my readers can recognize the absurdity of their claims. … increasing sunspots are linked to increases in earth temperature
