Share this…FacebookTwitterThe two recent dry summers seen in Europe have led to alarmists believing that the climate doomsday has arrived. But The European Institute for Climate and Energy (EIKE) looks at the past to see if this sort of thing is really unusual. ======================= German forests growing much faster today than 1000 years ago.

According to peer-reviewed science, Sweden was at least 3°C warmer than it is today about 6000 to 9000 years ago, when CO2 concentrations lingered around 265 ppm. At 410 ppm CO2, 21st century Sweden is colder now than almost any time in the last 9000 years. Image Source: Grudd, […]

Share this…FacebookTwitterCO2 concentrations have risen from 310 ppm to 410 ppm since the 1930s. However, there has been no net change in Arctic or Greenland temperatures during these last 90 years. During the Pliocene, CO2 also ranged between about 300-400 ppm, but the Arctic was 15-22°C warmer and sea levels 25 meters higher than today. […]

Life thrives when the globe gets tropically warm.

Share this…FacebookTwitterCO2 concentrations ranged between 180 ppm to 220 ppm from about 15 to 60 thousand years ago. Several new temperature reconstructions indicate there were millennial-scale periods with multiple degrees Celsius greater warmth than today (410 ppm CO2) during this glacial period.

Share this…FacebookTwitterIn recent decades, the Earth’s seas have been rising at a rate of under 0.8 mm/year (8 cm per century) according to estimations of the sum of contributions to sea level rise. In contrast, sea levels rose at rates of more than 40 mm/year ~10,000 years ago. Relative sea level rise can be calculated […]

The authors of a new study (Jiao et al., 2019) point out that temperature changes in the Tianshan mountains are “mainly influenced by the solar activity via the mean minimum temperature within approximately 11-year periods.” Despite some warming since […]

Between 9000 to 6000 years ago, when global temperatures were 4-6°C warmer than they are today, the Sahara was a tree- and lake-covered haven teeming with megafauna and human civilizations (Manning and Timpson, 2014).

Seas rose and fell by multiple meters (-5 m to +3 m) within 1250 years until as recently […]
