Claim:
"The official observed temperatures are coming consistently below the scary global warming numbers"; "Melting polar ice triggers ice age"
Scientists who reviewed the article found that it builds on a collection of misleading and false claims. For instance, Koonin states that “Greenland’s ice sheet isn’t shrinking any more rapidly today than it was eighty years ago”. Contrary to the claim, scientific studies using airborne and satellite altimetry observations show considerable thinning has occurred along the margin of the Greenland ice sheet since 2003.
Claim:
There is no factual data to back up global warming; real scientists don’t know whether CO<sub>2</sub>, solar sunspots or natural activity cause global warming
“The article is good overall, although there are two small issues. First, the title seems to overestimate the results. The scientific study the National Geographic article is based on cannot account for all of the climate forcers, as there are no Amazon basin wide estimates (as clearly stated in the study). This drawback could potentially change the overall warming effect, and therefore the title seems to exaggerate.”
Claim:
Science said in the: 70s, another ice age in 10 years; 80s, acid rain will destroy all crops in 10 years; 90s: the ozone layer will be destroyed in 10 years; 2000’s the ice caps will be gone on 10 years
