CLAIM REVIEWS

Climate change, forest management and several other causes contribute to wildfire severity and total area burned in the western United States

CLAIM
“Forest fires are caused by poor management. Not by climate change.”

SOURCE: Anonymous, Facebook

Published: 16 Sep 2020

VERDICT

Planting trees can help mitigate some aspects of climate change, but it cannot solve all environmental crises

CLAIM
“Trees provide a solution to almost all environmental crises we're facing. Trees reverse climate change by cleaning carbon from the air.”

VERDICT

The long-term survival of polar bears is threatened by loss of sea-ice due to global warming, new study confirms

CLAIM
"Global warming is driving polar bears toward extinction"

SOURCE: Henry Fountain, The New York Times

Published: 27 Jul 2020

VERDICT

Greenhouse gases cause global warming by trapping infra-red radiations, not by “causing more holes in the ozone layer”

CLAIM
Greenhouse gases emitted into the ocean are causing more holes in the ozone layer … “the ozone layer has holes in it causing global temperature to rise”

SOURCE: Otis Holland, Instagram

Published: 21 Jul 2020

VERDICT

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.

SOURCE: Mark Mathis, Clear Energy Alliance

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"

SOURCE: Chris Pollard, The Sun

Published: 20 May 2020

VERDICT

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

CLAIM
The polar bear population has been growing. Polar bears are thriving even where sea ice is diminishing.

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.

SOURCE: Holger Douglas, Tichys Einblick

Published: 02 May 2020

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.
