On the Futility of Long-Range Numerical Climate Prediction

Note: two events at AGU13 this morning dovetail in with this essay. The first, a slide from Dr. Judith Lean which says: “There are no operational forecasts of global climate change”. The second was a tweet by Dr. Gavin Schmidt, … Continue reading

Geoengineering approaches to reduce climate change unlikely to succeed

From the EGU: Heavy rainfall events can be more common in a warmer world (Credit: Annett Junginger, distributed via imaggeo.egu.eu) Reducing the amount of sunlight reaching the planet’s surface by geoengineering may not undo climate change after all. Two German … Continue reading

Study predicts the sun is headed for a Dalton-like solar minimum around 2050

Method uses the Ap geomagnetic index, which has been in a slump since October 2005: The Hockey Schtick tips us to a paper published today in Advances in Space Research predicts that if the current lull in solar activity “endures … Continue reading

Study: lack of cloud physics biased climate models high

The Hockey Schtick brings this to our attention. It seems Dr. Roy Spencer was prescient with his observation: “The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the atmosphere … Continue reading

Spectacular video: Comet ISON imaged from a Langrange point in space

NASA’s Solar Terrestrial Relations Observatory, or STEREO, is monitoring Comet ISON as it approaches the sun. NASA’s twin Solar Terrestrial Relations Observatory (STEREO) spacecraft are parked in Langrange zones, known as the L4 and L5 Lagrangian points, each centered about … Continue reading

The ‘worse than we thought’ model

From ETH Zurich: Underestimated future climate change? 25.11.2013 | Fabio Bergamin New model calculations by ETH researcher Thomas Frölicher show that global warming may continue after a stoppage of CO 2 emissions. We cannot rule out the possibility that climate … Continue reading

National Academy of Sciences: climate models still ‘decades away’ from being useful

From the National Academy of Sciences report A National Strategy for Advancing Climate Modeling: Computer models that simulate the climate are an integral part of providing climate information, in particular for future changes in the climate. Overall, climate modeling has … Continue reading

Svensmark’s cosmic ray theory of clouds and global warming looks to be confirmed

Note: Between flaccid climate sensitivity, ENSO driving “the pause”, and now this, it looks like the upcoming IPCC AR5 report will be obsolete the day it is released. From a Technical University of Denmark press release comes what looks to … Continue reading

Short Meteorological Memories

Guest essay by Alan Caruba I am giving thanks this week, despite the heat wave, that I have not read, nor heard, a single claim that it is proof that global warming has arrived and we are all doomed. By … Continue reading

Length of day governed by Earth’s core processes

From the University of Liverpool , something I found interesting because a few years ago, former State Climatologist Jame Goodridge said he saw correlations between length of day and other atmospheric processes. Research reveals Earth’s core affects length of day … Continue reading

Call for essays: The 2013 Matt Ridley Prize

The Matt Ridley prize for exposing environmental pseudoscience was inspired by Matt’s discovery that a Ridley family trust was making money from a wind farm company. All too often, hysterical groupthink, based on bad science, creates a climate in which politicians intone … Continue reading

An Engineer’s Take on Climate Change #2

Guest essay by Ronald D. Voisin High Atmospheric CO2 is Good for All Life on Earth At an atmospheric concentration of 380ppm and higher the limited long-wave spectral absorption of CO2 is essentially saturated. Consequently, yet more atmospheric CO2 becomes … Continue reading
