New study identifies the top 90 producers of industrial carbon emissions

New study identifies the top 90 producers of industrial carbon emissions

This weeks publication in the journal Climatic Change by Richard Heede on Tracing anthropogenic carbon dioxide and methane emissions to fossil fuel and cement producers, 1854–2010 provides a robust scientific basis for motivating fresh thinking and dialogue about responsibility for taking action to address climate change. The responsibilities for climate change fall on many shoulders, … learn more→

Rising temperature, rising food prices

Rising temperature, rising food prices

Agriculture as it exists today developed over 11,000 years of rather remarkable climate stability. It has evolved to maximize production within that climate system. Now, suddenly, the climate is changing. With each passing year, the agricultural system is becoming more out of sync with the climate system. In generations past, when there was an extreme … learn more→

China can teach the West about tackling climate change

China can teach the West about tackling climate change

China has become a popular target of environmental ire, drawing criticism for its soaring carbon emissions and perceived intransigence during climate negotiations. Nonetheless, an easy target isn’t always a legitimate one. The charges frequently levelled at China mask the country’s historic, and I would argue instructive, efforts to mitigate climate change. Consider the tenor adopted … learn more→

Who will speak up for climate change adaptation?

Who will speak up for climate change adaptation?

As with the federal elections of 2007 and 2010, climate change appears set to feature again in the forthcoming September poll. Yet one of the most important aspects of the issue, that of adaptation to climate change, is again unlikely to garner any attention. Climate change and its associated global changes (prominently sea level rise … learn more→

Where has all the Ice gone?

Where has all the Ice gone?

As the earth warms, glaciers and ice sheets are melting and seas are rising. Over the last century, the global average sea level rose by 17 centimeters (7 inches). This century, as waters warm and ice continues to melt, seas are projected to rise nearly 2 meters (6 feet), inundating coastal cities worldwide, such as … learn more→

How we lost 20 years on climate change action

How we lost 20 years on climate change action

Scientists have warned about the “greenhouse effect” for years. Now it is no longer a scientific nightmare; it has arrived. Lines from Al Gore’s famous movie? No. The Sydney Morning Herald published these words in mid-1988. The article detailed record-breaking heat and drought in North America and elsewhere, linking these weather effects with predictions for … 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 storm of stupidity? Sandy, evidence and climate change

A storm of stupidity? Sandy, evidence and climate change

“It’s global warming, stupid” – Bloomberg’s Businessweek cover last week left little doubt about their opinion concerning “Frankenstorm” Sandy. The accompanying tweet anticipated that the cover might “generate controversy, but only among the stupid.” These frank words about the Frankenstorm are perhaps long overdue in light of the general failure of American politicians to show … learn more→

Arctic Sea Ice in Free Fall

Arctic Sea Ice in Free Fall

The North Pole is losing its ice cap. Comparing recent melt seasons with historical records spanning more than 1,400 years shows summer Arctic sea ice in free fall. Many scientists believe that the Arctic Ocean will be ice-free in the summertime within the next decade or two, and some say that this could occur as … learn more→

Whiter than white: could brightening clouds reduce symptoms of climate change?

Whiter than white: could brightening clouds reduce symptoms of climate change?

Marine cloud brightening: it’s a concept that has been floated in climate engineering discussions for some time. But what are the moral implications of this geoengineering technology, and how likely is it to be implemented? What is cloud brightening? Cloud brightening is the idea that we could increase a cloud’s albedo (reflectivity) to reflect a … learn more→
