CO2 theory called into question…inconvenient truths emerge
A new study by Bierman et al titled: Plant, insect, and fungi fossils under the center of Greenland’s ice sheet are evidence of ice-free times, shows that “in the middle of Greenland, where a three-kilometer-thick ice sheet now sits, plants and insects once flourished and at CO2 levels well below today’s levels.” – Report 24

Hotter with less CO2? That puts the CO2 global warming theory on its head.
14°C warmer with 35% Less CO2
The scientists have proven that central Greenland was completely ice-free in the recent geological past – around 250,000 to 1.1 million years ago – at a time when the atmospheric CO2 content was between 275 and 290 ppm, compared to 420 today.
During drilling on the GISP2 project, researchers found some surprises: remains of poppies, moss ferns, wood tissue and insect parts. That means where we have perpetual ice today, there was once abundant life and warmth not long ago. The scientists estimate a July mean temperature of between +3 and +7°C compared to the -7°C measured today.
According to Germany’s online Report24 here,
What is particularly interesting is that the CO2 concentration of this ice-free period corresponds almost exactly to the values of the “Little Ice Age” between 1700 and 1900.” […] “The study raises fundamental questions. For example: If Greenland could be ice-free at low CO2 levels, what factors really determine whether it freezes or thaws? The answer is likely to be more complex than some climate hysterics would like.”
Such warmth, at Little Ice Age CO2-levels, is a very inconvenient fact for the climate alarmists and it suggests that the climate system is indeed far more complicated than the straight line CO2-temperature claims made by the government-funded scientists and non-questioning media want us to believe.
They’ve got some explaining to do.
