Evidence of RWP In Florida

The work of experts such as Sylvia Hallam has been ignored in favour of computer models and global warming theory. It is good to see another study that prefers real…

Climate regulation changed with the proliferation of marine animals and terrestrial plants

“The shift from a Precambrian Earth state to the modern state can probably be attributed to major biological innovations – the radiation of sponges, radiolarians, diatoms and land plants.”

Melting Glaciers Revealing Ancient Tree Stumps from a Warmer Period

Ancient tree stumps found under glaciers in Southeast Iceland are confirmed to be roughly 3,000 years old, RUV reports. A specialist believes the remarkably well-preserved stumps were part of a…

Climate changed the size of our bodies and, to some extent, our brains

A global context for Man-made Climate Concerns

Therefore whatever CO2 reductions and sacrifices of wellbeing are made in the Western World will be overtaken and soon exceeded by them. It should be realised that climate change policies…

How to compare today to the past

By Andy May In the last post, I discussed the problems comparing modern instrumental global or hemispheric average temperatures to the past. Ocean temperature coverage was sparse and of poor…

More intense and frequent thunderstorms linked to global climate variability

Using isotopes from Texas cave stalactites, scientists in Texas A&M’s College Of Geosciences studied thunderstorm changes in the Southern Great Plains TEXAS A&M UNIVERSITY Research News Large thunderstorms in the…

Global Warming is happening, what does it mean?

By Andy May The concepts and data used to make temperature and climate reconstructions, or estimates, are constantly evolving. Currently, there are over 100,000 global weather stations on land and…

Several More New Studies Show Drought Is Now Less Common And Severe Than Centuries, Millennia Ago

Scientists continue to publish new drought reconstructions indicating there were far more frequent and severe drought periods in the past several thousand years than anything observed in the modern period.

Younger Dryas Impact Hypothesis Takes Another Self-Inflicted Gunshot Wound

Guest “Really?” by David Middleton H/T to my friend Brian Pratt…Introduction For starters, the author appears to totally fail to grasp the principle of uniformitarianism… Since its introduction in 2007,…

Antarctica wasn’t quite as cold during the last ice age as previously thought

An international team of scientists, led by Oregon State University’s Christo Buizert, has found that while parts of Antarctica were as cold as 10 degrees below current temperatures, temperatures over…

Meltwater Pulse 1A

A fiery past sheds new light on the future of global climate change

Many of today’s climate models rely on past levels of greenhouse gasses and aerosols to validate their predictions for the future. But there’s a problem: While pre-industrial levels of greenhouse…

A Review of Temperature Reconstructions

By Andy May This is an update to a 2016 post; the original post is here. We often hear that the planet is warming faster than ever before, or at…

The anatomy of past abrupt warmings recorded in Greenland ice

Data availability and temporal resolution make it challenging to unravel the anatomy (duration and temporal phasing) of the Last Glacial abrupt climate changes. Here, we address these limitations by investigating…

Ocean temperature reconstructed over the last 700,000 years

Bern’s ice core researchers were already able to demonstrate in 2008 how the concentration of CO2 in the atmosphere has changed over the past 800,000 years. Now, using the same…

Poop core records 4,300 years of bat diet and environment

“As a piece of work showing what you can do with poo, this study breaks new ground,” said Michael Bird, a researcher in environmental change in the tropics at James…

PAGES 12K: The Ice Age Goeth

Guest “damning with faint praise” by David Middleton Kaufman, Mckay, Routson, et al., 2020 In my previous post, I noted a “funny pattern” in the latest Holocene climate reconstruction (Kaufman,…

PAGES 12K… A funny thing happened on the way to the Anthropocene!

Guest “A funny thing happened on the way to the Anthropocene” by David Middleton I’ve been studying a recent Holocene climate reconstruction (Kaufman, D., McKay, N., Routson, C. et al., 2020)……

Its a Bit more Complicated

The plant matter stuff reported in PNAS is obviously true. So Greenland did mostly melt about 1 mya; otherwise those plants could not have existed there then, however briefly. But…

Tree Remnants Show Greta’s Thunberg’s Northern Sweden Was 3°C Warmer 9300 Years Ago…Trees Where There’s Tundra

9300-year old vegetation remnants found under receding glaciers in Northern Sweden show that the trees once grew where tundra exists today, meaning it was warmer.

Claim: Important climate change mystery solved by scientists

The long-standing mystery is called the “Holocene temperature conundrum,” with some skeptics contending that climate model predictions of future warming must be wrong. The scientists say their findings will challenge…

Past river activity in northern Africa reveals multiple Sahara greenings

“By combining the sediment analyses with results from our computer simulation, we can now precisely understand the climatic processes at work to explain the drastic changes in North African environments…

Claim: Climate and carbon cycle trends of the past 50 million years reconciled

Predictions of future climate change require a clear and nuanced understanding of Earth’s past climate. In a study published today in Science Advances, University of Hawai’i (UH) at Mānoa oceanographers…
