Share this…FacebookTwitterScientists have found sea levels on India’s eastern coast were still 1-1.5 m higher than today as recently as 500 to 300 years ago and 3-4 m higher than today between 6000 to 4000 years ago. Seas rose and fell by multiple meters (-5 m to +3 m) within 1250 years until as recently […]

The globe was about 4 to 6°C warmer than it is today between 9000 and 6000 years ago, when CO2 concentrations centered around 265 ppm. Image Source: ScienceDaily.com Some regions exceeded the […]

In contrast, this region was ice free with open water conditions during the Early Holocene (9,500-5,800 years ago). Berben et al., […]

Extinctions have not been linked to a warming climate or higher CO2 levels. In fact, since the 1870s, species extinction rates have been plummeting.

Evidence from the tropical Atlantic indicates today’s regional temperatures (15.5°C) are 7.5°C colder than a peak temperatures (23°C) between 15,000 to 10,000 years ago, when CO2 hovered around 220 ppm.

Share this…FacebookTwitterA new paper indicates the rise in CO2 concentration occurred well after the Northern Hemisphere’s ocean circulation changes drove the abrupt warming (~11,700 years ago) that ended the last ice age – a lag that effectively leaves no causal role for CO2 during deglaciation.

Because CO2 concentrations changed very modestly during the pre-industrial Holocene (approximately ~25 ppm in 10,000 years), climate models that are predicated on the assumption that […]
