CLAIMS REVIEWED

There is overwhelming evidence that current climate change is significantly caused by human carbon emissions contrary to claim in Townhall

CLAIM
"Human-produced carbon might be one of the factors [of climate change], but there’s simply no evidence that it is a significant one."

SOURCE: Kurt Schlichter, Townhall

Published: 11 Sep 2019

VERDICT

Earth’s orbit cannot explain modern climate change

CLAIM
"changes in the solar orbit of the earth, along with alterations to the earth’s axial tilt, are both responsible for what climate scientists today have dubbed as “warming”[...]. In no way, shape, or form are humans warming or cooling the planet"

SOURCE: Ethan Huff, Natural News

Published: 03 Sep 2019

VERDICT

Claim that cosmic rays are a crucial player for current climate change is unsupported

CLAIM
"Based on the increase of solar activity during the twentieth century, it should account for between half to two-thirds of all climate change"

SOURCE: Cap Allon, Nir Shaviv, Electroverse

VERDICT

Non-peer-reviewed manuscript falsely claims natural cloud changes can explain global warming

CLAIM
"During the last hundred years the temperature is increased about 0.1°C because of carbon dioxide. The human contribution was about 0.01°C."

VERDICT

Natural variability can not explain modern global warming, as Heartland Institute report claims

CLAIM
"Neither the rate nor the magnitude of the reported late twentieth century surface warming (1979–2000) lay outside normal natural variability."

SOURCE: Craig Idso, Robert Carter, S. Fred Singer, Heartland Institute

Published: 30 May 2017

VERDICT

The Sun cannot explain recent global warming, contrary to what Heartland Institute report claims

CLAIM
"Solar forcings are not too small to explain twentieth century warming. In fact, their effect could be equal to or greater than the effect of CO2 in the atmosphere."

SOURCE: Craig Idso, Robert Carter, S. Fred Singer, Heartland Institute

VERDICT

Daily Mail inflates data handling disagreement between scientists; makes unsupported “manipulation” accusation
