There’s a reason no one can agree about climate change, and on some level, it’s the same reason you curse the gods on rainy days when the forecast said sunny. Meteorology and climate science, in general, are complicated and speculative — reliant on mathematical models that aren’t always fully accurate to paint pictures of yesterday, […] … learn more→

1. Do you think climate change is an urgent problem? 2. Do you think getting the world off fossil fuels is difficult? Those are the questions with which Gernot Wagner of the Environmental Defense Fund and Martin L. Weitzman of Harvard begin Climate Shock: The Economic Consequences of a Hotter Planet (Princeton University Press). The […] … learn more→

Then, another average is calculated for each month of the year for […] … learn more→

The Australian Academy of Sciences today released the new The Science of Climate Change: Questions and Answers. This is an extensively revised update of a similar publication in 2010. Its stated purpose is to “provide an understanding based on our present scientific knowledge, of some key questions about climate change”. What is notable about the […] … learn more→

In last month’s State of the Union address, President Obama sounded the alarm on climate change, pausing to enumerate his administration’s accomplishments but also underscoring the problems that lie ahead. Though his speech encompassed myriad issues facing the American public, Obama emphasized that \”no challenge—no challenge—poses a greater threat to future generations than climate change.\” […] … learn more→

Climate change is as much an economic problem as an environmental one. The effects of climate change, such as damage from more severe weather or health problems from higher temperatures, will impose a cost on society. On the other hand, moving away from a fossil fuel-based energy system will require significant investments into low-carbon technologies. […] … learn more→

Last year, as the summer heat broke, a congregation of climate scientists and communicators gathered at the headquarters of the American Association for the Advancement of Science, a granite edifice erected in the heart of Washington, to wail over their collective futility. Year by year, the evidence for human-caused global warming has grown more robust. […] … learn more→
