Iron is a vital nutrient for marine life and plays a significant role in regulating atmospheric carbon dioxide by influencing the growth of phytoplankton, which absorb carbon dioxide.

Analysis of ocean sediments has surfaced geochemical clues in line with the possibility that an encounter with a disintegrating comet 12,800 years ago in the Northern Hemisphere triggered rapid cooling of Earth’s air and...

A previously untapped source of data sheds new light on the climate of the early Earth: fossilized dinosaur teeth show that the atmosphere during the Mesozoic era, between 252 and 66 million years ago, contained far more...

Such weather variations often resulted in catastrophes, related directly or indirectly to the climate. These included 30 years during which the Black Death ravaged the land, 23 years or famine, and nine years during which...

Holocene (11,700 to 8,200 years ago) Arctic (Svalbard) temperatures “were up to 9°C higher than today” according to the authors of a new Nature journal study...

This final part of the series explores the issue of regulation of Earth’s climate in light of a small, continuing imbalance between energy input from Sol, and outgoing LWIR - the so-called Earth Energy Imbalance (EEI)...

By Andy May My last post on the AMO and HadCRUT5 generated some interest and some criticism. As I explained, there are two common methods of computing the AMO index.…

Paleoclimate records reveal prehistoric floods that far exceed anything we see today — undermining claims that modern flooding is “unprecedented” or driven solely by climate change.

By Andy May In this post I examine the proxies used to compare CO2 to temperature from 66 million years ago (Ma) until today and comment on the quality of…

Earth's transit of the "Radcliffe Wave" may have been a significant driver of Middle Miocene climate change.

Earth's transit of the "Radcliffe Wave" may have been a significant driver of Middle Miocene climate change.

The paper incorrectly claims that recent warming is a new phenomenon, but provides no data to back this up. However many tree line studies have conclusively shown that tree lines in the Rockies were much higher than now...

By Andy May I last wrote about Climate Change and Civilization for the past 4,000 Years in 2016. Since then, a lot has changed, and I’ve learned a lot more…

The climate is changing, and the geological record of climate change clearly shows that (a) we live in an unusually cold climate, (b) recent warming is neither dangerous or unusual, and (c) the main drivers of climate change...

In about 120 million years we will finally cross the Sagittarius spiral arm. We will exit this Ice House with its periodic glacial ages and enter the next Hot House inter-arm space on our way into the next spiral arm region...
