It’s cold and my car is buried in snow. Is global warming really happening?

It’s cold and my car is buried in snow. Is global warming really happening?

For years, climate contrarians have pointed to snowfall and cold weather to question the scientific reality of human-induced climate change. Such misinformation obscures the interesting work scientists are doing to figure out just how climate change is affecting weather patterns year-round. Understanding what scientists know about these effects can help us adapt. And, if we … learn more→

Increases in rainfall extremes linked to global warming

Increases in rainfall extremes linked to global warming

Rainfall extremes are increasing around the world, and the increase is linked to the warming of the atmosphere which has taken place since pre-industrial times. This is the conclusion of a recent study which investigated extreme rainfall trends using data from 8326 weather-recording stations globally, some of which have records spanning more than a hundred … learn more→

Best of 2012: Why the global warming skeptics are wrong

Best of 2012: Why the global warming skeptics are wrong

The threat of climate change is an increasingly important environmental issue for the globe. Because the economic questions involved have received relatively little attention, I have been writing a nontechnical book for people who would like to see how market-based approaches could be used to formulate policy on climate change. When I showed an early … learn more→

A crucial benchmark for climate action is at risk. Why it matters now more than ever.

A crucial benchmark for climate action is at risk. Why it matters now more than ever.

Several recent reports have pointed out that without significant, immediate action to lower global warming emissions, we are getting dangerously close to blowing past emissions levels that would lead to a 2°C or more increase in global temperatures. That may lead some to think that the 2°C benchmark is becoming increasingly irrelevant, but nothing could … learn more→

Journeys to the ends of the earth

Journeys to the ends of the earth

Over the past decade, global warming has melted polar sea ice down to record lows—but during the same period, thanks to a growing awareness of the climate phenomenon, the Arctic and the Antarctic have vastly expanded in the popular imagination. Nowhere is that clearer than in the broad recent interest in the European, Russian, and … learn more→

Negotiation nostalgia: How Diplomats negotiate international agreements

Negotiation nostalgia: How Diplomats negotiate international agreements

I’m not in Rio de Janeiro. I’m in DC now, although as the weather heats up to the 90s today, and maybe up to 100 tomorrow, I’m thinking more and more that I should have found some excuse to go to the Rio+20 meeting. Even on the warmest days the beaches and the breezes, not … learn more→

The charcoal challenges: fire and climate dynamics

The charcoal challenges: fire and climate dynamics

The United Nations Environment Programme (UNEP) is co-ordinating a new venture to tackle short-lived global warming agents such as black carbon. Should we be paying more attention to black carbon? Yes, indeed we should, because black carbon plays complicated and multi-faceted roles in global carbon dynamics. It also poses some deep research challenges and moral … learn more→

Global Warming: Do individual choices matter?

Global Warming: Do individual choices matter?

If you had asked me that question just a year ago, I probably would have expressed skepticism. I have covered climate change as a science journalist for more than two decades and care deeply about the issue. But I’ve always thought of it as problem to be solved on the national or international level. So, … learn more→

10,000 simulations show warming of 1.4-3ºC by 2050

10,000 simulations show warming of 1.4-3ºC by 2050

A project running almost 10,000 climate simulations on volunteers’ home computers has found that a global warming of 3 degrees Celsius by 2050 is ‘equally plausible’ as a rise of 1.4 degrees. The study, the first to run so many simulations using a complex atmosphere-ocean climate model, addresses some of the uncertainties that previous forecasts, … learn more→

Forget Kyoto – climate bonds will drive the green revolution

Forget Kyoto – climate bonds will drive the green revolution

If no-one argues against the proposition that it was capitalism that created the global warming problem, then no one can argue that it must therefore be capitalism that will solve the problem. But how can capitalism solve the problem of global warming? The answer: by financing the transition to a clean energy economy. This is … learn more→
