“While the variations in the Sun’s magnetic activity (leading to small variations in solar radiation reaching the Earth) have some discernible effect on our climate, their impact is small compared to the effects of man-made greenhouse gas emissions.”
“Although the presented facts are clear, the scientists give a personal interpretation of the priorities and needed policies, which are not covered in the source. The data give added value, but are in line with earlier studies.”
Claim:
The rate of warming according to the data is much slower than the models used by the IPCC
“The article correctly links estimates of current carbon dioxide emissions from land use and land cover change with fairly conservative estimates for potential carbon sequestration embedded in “natural climate solutions” as part of the climate mitigation strategy to avoid 1.5°C warming.
Land-use and land-cover change is responsible for roughly 10-15% of total global carbon dioxide emissions. Forest management, reforestation, and afforestation where appropriate, is part of the climate mitigation portfolio assessed by Integrated Assessment Models used in the IPCC process.”
This op-ed in USA Today makes the claim that Hurricane Florence has no appreciable contribution from human-caused climate change.
Scientists who reviewed the article found that it ignores the evidence for trends in tropical cyclone behavior, including slower movement speed and more intense rainfall. Additionally, sea level rise raised the storm surge of the landfalling tropical cyclone above the level it would have reached a century ago. The article cherry-picks data in misleading way to claim that recent storms are no different from past tropical cyclones…
“The article is clear and accurate. The authors have consulted several experts in the field to develop this story. They provide a scientifically sound overview of the current sea ice state north of Greenland, its historical context, and what has caused this anomaly.”
Claim:
there is no relationship between temperature and carbon dioxide emissions by humans[...] carbon dioxide has had a minuscule effect on global climate
Claim:
The atmospheric residency time of carbon dioxide is five years and it is quickly sequestered into plants, marine life, oceans and sediments.
“This article is an amalgamation of logical fallacies, misleading talking points, and downright factually incorrect statements regarding the physics of the climate system. Every talking point in this article has been debunked many times over and it is astonishing that this was published.”
“The article reasonably summarizes a new study published in PNAS, which describes the potential of tipping elements to enhance climate warming and the potential for the Earth to transition into a hot-house climate state. The article is careful to point out uncertainties and thus avoids being sensational. However, there are many small errors scattered throughout the article.”
