New research into cloud formation suggests increased climate sensitivity

Research Suggests Climate Models Underestimate Climate Sensitivity

Climate models are wrong? Climate models are mathematical representation of an enormously complex system. They are intended to project trends, not predict events. They are an imperfect but indispensable tool to gain an understanding of what we can likely expect in the future. Casting doubt on the reliability of climate models is a common theme among climate skeptics who commonly claim that…

Slight Uptick in U.S. New Vehicle Fuel Economy in July

U.S. fuel economy near record high As we reported early last June, new vehicle fuel economy (window-sticker value) in the U.S. hit an all-time high in May of 25.7 miles per gallon (MPG) as reported by the University of Michigan Transportation Research Institute. June saw a slight dip in fuel economy, off 0.2 to 25.5 MPG. The institute just released their research…

The next generation - Next Generation Science Standards

Climate Science Students Bill of Rights

The battle for science education in our schools Our human existence in the modern world is utterly dependent on science and technology. Yet the troubling trend in the U.S. is that science education, mathematics and critical thinking skills are declining. Some argue that the decline of science, technology, engineering and math education (STEM) has never been that good or that…

We need to fully understand geoengineering, even if to better realize what a bad idea it is

Geoengineering – Insanity? All the More Reason to Discuss It

Is geoengineering pure insanity? Maybe we should talk about it Is geoengineering the key to solving the global climate change problem? That’s the kind of question that evokes a knee-jerk reaction from those how consider it, including me. I believe we’re already doing enough geoengineering on the planet, albeit unplanned and perhaps unintended. For me, geoengineering like the kind environmental engineer David…
