The Defeat of Climate Denial

February 4, 2015 by Steven Cohen

Over the weekend, a poll was released indicating Americans have conclusively rejected climate denial and understand the reality of climate change. According to the survey, "An overwhelming majority of the American public, including half of Republicans, support government action to curb global warming."[read more]

Science, Policy, and Decision Making

January 27, 2015 by Steven Cohen

Willful ignorance of climate science is troubling. Disregard of ecological science is destructive. The failure to utilize medical science can be life threatening. But my deeper concern is the attitude toward knowledge and learning expressed by these supposed national leaders.[read more]

Competent Leaders Need to Understand the Science of Sustainability

July 8, 2014 by Steven Cohen

In speaking about climate policy last week, President Obama chided senators who are trying to dodge the climate issue by claiming they were not scientists. The president went on to claim that he was not a scientist either, but that "I've got this guy, John Holdren. He's a scientist."[read more]

Nature CLOUD Study Author: ‘The Climate May Be More Sensitive Than Previously Thought’

October 18, 2013 by Joseph Romm

Sensitive Environment

Switzerland's CERN, the world's leading particle physics laboratory, has released new research that would actually suggest that the climate change and the environment’s sensitivity to carbon dioxide may in fact be higher than expected.[read more]

Climate Science for Beginners

October 14, 2013 by Lindsay Wilson

Beginner Climate Science

Does it infuriate you when people conflate measurements of carbon and carbon dioxide? Do you know your equilibrium climate sensitivity from your transient climate response? How about the relative importance of carbon dioxide, carbon monoxide and black carbon in terms of radiative forcing?[read more]

Against Anti-Science Tribalism

August 6, 2013 by Roger Pielke, Jr.

Just as there are indeed a few people who deserve to be equated with Nazis, there are probably a few who are truly anti-science. However, the overuse of the term in debates over science and politics diminishes our debates and subtracts from what we might learn from each other.[read more]

Climate Change Predictions a Double-Edged Sword

There is no greater danger to support for action on important issues of human impacts on the environment than an overselling of what climate science can provide.[read more]

Scientagonism: The Problem of Antagonistic Science Communication

January 7, 2013 by Steve Skutnik

A recent column by Daniel Sarewitz in Nature on bridging the "partisan divide" with respect to public perception of science inspired some spirited debate over on my twitter feed yesterday. Scientists are often perceived as being in the thrall of Democrats, , exposing the greater scientific enterprise to being undermined as simply another partisan front. But is it really that simple?[read more]

Two Studies Now Confirm Extreme Weather Caused by Global Warming

August 13, 2012 by David Hone

A recent analysis shows how the distribution of summer temperatures has shifted in recent decades, to the extent that there has been a notable change in the frequency of what were extreme outlying events. This in turn led NASA to assert that “the recent bouts of extremely warm summers, including the intense heat wave afflicting the U.S. Midwest this year, very likely are the consequence of global warming”.[read more]

Extreme hot weather in the USA and climate change

July 5, 2012 by David Hone

The current spate of very hot weather across much of the USA (and not forgetting the balmy “winter” days in many states back in the early part of the year) raises the question of the role of climate change in relation to such extremes.[read more]

Are Canada's oil sands to blame for rising atmospheric CO2?

May 22, 2012 by David Hone

In a recent New York Times opinion piece, NASA climate scientist James Hansen again puts forward his very compelling argument for strong action on limiting global CO2 emissions. He argues that Canadian oil sands is illustrative of an ongoing global trend to extract or mine increasingly challenging reserves of oil, gas and coal and bring them to market, a behaviour that could mean "game over for the climate".[read more]

Data, more data and climate change

March 15, 2012 by David Hone

Climate change is one of those subjects that is awash with data, leading to an almost endless capacity for analysis and ultimately conclusion drawing. The same data can be used to create different analytical output and a single analysis can lead to more than one conclusion. This comes about not just from the climate data itself, but from energy use data, energy use projections and the combination of all of these into both simple and highly complex models which seek to map out climate scenarios for the balance of this century and beyond.[read more]

How should climate change be taught?

February 23, 2012 by David Hone

The external release of documents relating to the activities of the Heartland Institute has raised many questions, but an important issue that is now in the open again relates to the teaching of climate change in schools. How should this be handled and what should be taught? Is there justification in arguing that “both sides” of the issue should be covered? Are there “two sides” to this issue? If so, what exactly are the “two sides”, particularly in the context of a high school education?[read more]

Science, risk management or just politics?

February 3, 2012 by David Hone

An opinion piece that appeared in the Wall Street Journal (Europe) on Tuesday (a few days earlier in the USA) presented the views of sixteen scientists on the issue of climate change under the heading “No Need to Panic About Global Warming“. Unfortunately there isn’t much in the way of science discussed and the reality of the policy world is very different from the story they have written.[read more]

Back to Basics on Climate Science

July 5, 2011 by David Hone

Last week I had the privilege to attend an MIT forum and listen to the keynote address given by Nobel laureate Mario Molina. The subject of the address was the issue of conveying an understanding of the science of climate change to the general public. Professor Molina won the Nobel Prize and is best known for his work in identifying the role of chloro-fluorocarbons in the destruction of the ozone layer.[read more]
