The continuing scientific climate research confirms what 97% of studies have previously determined: the northern latitudes, including the Arctic and Greenland, were considerably warmer in the past when CO2 levels were substantially below those of the 21st century.

The science facts are indisputable, natural forces and cycles frequently pushed the global climate into extremes of cooling and warming.

As this study found:

".....determined that (1) "maximum concentrations of chironomids, maximum occurrence of ephippia of the water flea Daphnia pulex, highest organic matter contents and lowest minerogenic input from c. 7700 to 4400 cal. a BP probably reflect the Holocene thermal maximum (HTM)," that (2) "the highest temperatures during the HTM are indicated around 7000 cal. a BP, when Salix arctica, which is considered a warmth-loving plant, had a maximum," that (3) "comparisons with Holocene records from East and North Greenland show similar immigration histories and similar trends, with the Little Ice Age as the coldest period during the Holocene, culminating about 150 years ago," and that (4) "subsequent warming does not indicate environmental conditions comparable to the HTM yet at this stage."
