Improved data set shows no global warming ‘hiatus’

National and international studies have shown that the Earth is warming, and with this warming, other changes are occurring, such as an increasing incidence of heat waves, heavy downpours and rising sea levels. In its Fifth Assessment Report in 2013, the Intergovernmental Panel on Climate Change found that the temperature of the Earth increased at […] … learn more→

Deniers vs alarmists? It’s time to lose the climate debate labels

The climate debate seems to be as polarised as ever. While joint political pledges offer some hope that climate change no longer has to be a partisan issue, a look at the comments below most articles on global warming says otherwise. Some put this is down to differing core values, others point to psychological outlooks. […] … learn more→

Sudden global warming 55m years ago was much like today

It is often said that humans have caused the Earth to warm at an unprecedented rate. However researchers have discovered another period, some 55m years ago, when massive volcanic eruptions pumped so much carbon into the atmosphere that the planet warmed at what geologists would think of as breakneck speed. The good news is that […] … learn more→

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

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

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.

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

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→

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→
