Untold Story of Climate’s Holocene Gift to Humanity

The development and maintenance of life on Earth have been greatly aided by the Holocene – sometimes called the age of man.

New evidence that polar bears survived 1,600 years of ice-free summers in the early Holocene

From Polar Bear Science Susan Crockford New evidence indicates that Arctic areas with the thickest ice today probably melted out every year during the summer for about 1,600 years during the…

The Last 12,000 Years Show a More Complex Climate History Than Previously Thought

Inconsistencies between Holocene climate reconstructions and numerical model simulations question the robustness of climate models and proxy temperature records.

New Study: Arctic Was Much Warmer 6000 Years Ago… 90% Of Glaciers, Ice Caps Smaller Than Present Or Absent!

Climate alarmists hate this inconvenient fact: hundreds of temperature reconstructions show that the northern hemisphere was much warmer over much of the past 10,000 years (Holocene) than it is today.

Climate Change in the Early Holocene

The team believes the creation of the cemetery reveals a social response to the stresses caused by regional resource depression.

More Evidence: Glaciers Existing Today Were Absent For Nearly All Of The Last 10,000 Years

So, once again, there is no evidence to support the alarmist claims that modern glacier extents are unprecedented or even unusual relative to the last 10,000 years – including the…

Those who don't learn from Yamal, are condemned to repeat it – Marcott’s YAD061

You’d think academics in the upside down Mann climate proxy world would pay attention, and not repeat the same mistakes of the past. Apparently not. WUWT readers surely recall the…
