An Engineer’s Explanation of Climate Change

It Takes a Hammer to Change Climate States By Ronald D Voisin In this essay I will attempt to describe an explanation of climate change that may likely pertain to many (most all) time-scales. But before I do, I would like to make some comments about ice-core analysis – salient and significant observations that nonetheless…

Breaking Hockey Sticks: Antarctic Ice Core Edition

Guest post by David Middleton Graphic: The relentless rise of carbon dioxide Ancient air bubbles trapped in ice enable us to step back in time and see what Earth’s atmosphere, and climate, were like in the distant past. They tell us that levels of carbon dioxide (CO2) in the atmosphere are higher than they have been…

Study: why CO2 levels are lower during global cold periods

From CALIFORNIA INSTITUTE OF TECHNOLOGY Deep-sea corals reveal why atmospheric carbon was reduced during colder time periods We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international team of scientists reveals one of…

Study: Ice age thermostat prevented extreme climate cooling

From the UNIVERSITAT AUTONOMA DE BARCELONA and the “department of settled science” comes another global climate thermostat story. Just last week, we were told the Earth had no thermostat. Gotta love it when climate science is so robustly definite, eh? Ice age thermostat prevented extreme climate cooling Atmospheric CO2 concentrations swung over a range of…

A perfect storm of fire and ice may have led to snowball Earth

From the HARVARD JOHN A. PAULSON SCHOOL OF ENGINEERING AND APPLIED SCIENCES Explaining a ‘once-in-a-billion-year event’ What caused the largest glaciation event in Earth’s history, known as ‘snowball Earth’? Geologists and climate scientists have been searching for the answer for years but the root cause of the phenomenon remains elusive. Now, Harvard University researchers have…
