Tiniest Ever Ancient Seawater Pockets Revealed
The surprising discovery of seawater sealed in what is now North America for 390 million years opens up a new avenue for understanding how oceans change and adapt with the…
Climate Physics w/ Professor William Happer on Saifedean Ammous’s THE BITCOIN STANDARD Podcast.
How does politicization affect science, and why does Professor Happer think that the more policy-driven a field is, the less trustworthy its conclusions are?
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.
Sea Level: The Geological “Control Knob” for Atmospheric CO2?
Guest “putting 2 and 2 together” by David Middleton This post is the nucleus of a hypothesis I’ve been trying to develop. It is a “work in progress” and not…
Key Phases of Human Evolution Coincide with Flickers in Eastern Africa’s Climate
Three distinct phases of climate variability in eastern Africa coincided with shifts in hominin evolution and dispersal over the last 620,000 years,
Record of Antarctic Ice Sheet Response to Climate Cycles Found in Rock Samples
“Antarctica has these interesting brines with no carbon in them, because it all precipitated out earlier, so when those brines are isolated from other sources of water they form opal,”…
Steven McIntyre vs. the Spawn of Yamal
Stephen McIntyre’s tweet thread is a delight for old timers of the Climate Wars and has resurrected the issue, or at least the region, of the Enchanted Larch of Yamal.…
Are fossil-fuel CO2 emissions good or bad?
By Andy May This is the transcript, with minor edits to get it into blog post format, of my keynote speech to the Division of Professional Affairs, at the second…
Global Warming Spawned the Age of Reptiles
Harvard researchers find rapid evolution of reptiles was triggered by nearly 60 million years of global warming and climate change
The Two Degree Limit
By Andy May For decades We have been told that we must not let global warming exceed two degrees Celsius above the “pre-industrial” global average temperature. Recently the IPCC lowered…
Stronger Overturning Circulation in the Pacific During the Last Glacial Period
Data from fossil corals points to changed circulation of ocean currents – an important finding for climate models
Claim: Hidden in Caves: Mineral Overgrowths Reveal Unprecedented Modern Sea-Level Rise
The team found evidence of a previously unknown 20 centimeter sea-level rise that occurred nearly 3,200 years ago when ice caps melted naturally over the course of 400 years at…
Droughts in the sixth century paved the way for Islam
Extreme dry conditions contributed to the decline of the ancient South Arabian kingdom of Himyar.
New Research Questions Hypotheses About Climate-Controlled Ecosystem Change During the Origin of Dinosaurs in Argentina
In the middle of the formation, the researchers observed a clear change in conditions approximately from warmer, drier conditions to more temperate humid conditions, but no concurrent major changes could be identified…
New Study Finds Extreme, Severe Drought Impacting the Upper Colorado River Basin in the Second Century
While there has been research showing extended dry periods in the southwest back to the eighth century, this reconstruction of the Colorado River extends nearly 800 years further into the…
Climate Change Reveals Unique Artefacts in Melting Ice Patches
In recent years, hundreds of such discoveries have been made in ice patches, revealing traces of hunting, trapping, traffic, animals and plant life – small, frozen moments of the past.
