Time to Bury a Dangerous Legacy – Part II

Alan Robock March 17, 2008
Alarm about nuclear weapons and the irreversible harm that detonation might cause for the globe prompted nations to sign the Treaty on the Non-proliferation of Nuclear Weapons, which went into force in 1970. Signatory nations without weapons agreed to not pursue the research, and nations with them agreed to reduce the numbers. But with the end of the Cold War, public fear about nuclear warfare...

Are the Grandkids Worth the Money?

Eduardo Porter March 14, 2008
Any society can be judged by how much it cares for future generations - by preserving a record of history and also conserving resources and the environment. Some public spending reflects regard for future generations, and writing for the New York Times, Eduardo Porto poses the question: How much should the world sacrifice today to abate future costs of climate change? Much of modern society...

Carbon Prices, Not Quotas

Ernesto Zedillo March 11, 2008
For now, while oil and coal are still relatively plentiful, burning fossil fuels is the least expensive method in harnessing energy for transportation, heating, electricity and industrial development. Controlling emissions carries extra costs, and few countries want to take that step on their own – even though the global strategy of procrastination means putting the burden on future generations....

Insect Explosion “A Threat to Food Crops”

Steve Connor February 15, 2008
After studying a warming trend in the Earth’s fossil record from 55.8 million years ago, scientists with Pennsylvania State University predict rising carbon-dioxide levels and insect populations. An increase in carbon dioxide will decrease nutrients available in plants and thus lead to insects eating more leaves. Researchers have not pinpointed the cause behind the ancient warming period, but the...

Time to Move to a Second Generation of Biofuels

Christopher Flavin February 15, 2008
The indirect costs of growing biofuels outweigh any benefits, report two studies in the journal Science. A new political and economic response is required on biofuels, suggests Christopher Flavin, president of the Worldwatch Institute, in response. The US government now provides tax incentives to farmers for growing crops that can be turned into energy, which has increased prices of biofuel crops...

Biofuels Deemed a Greenhouse Threat

Elisabeth Rosenthal February 8, 2008
Studies suggest that, when all costs are considered, biofuels cause more greenhouse gas emissions than conventional fuels, according to The New York Times. As the US and other nations search for energy alternatives to fossil fuels, special interests in must-win states for the presidential election have promoted biofuel products. Besides adding to greenhouse gas emissions, development of biofuels...

Scientists Identify “Tipping Points” of Climate Change

Steve Connor February 7, 2008
The globe’s weather is not a constant. Oceans store heat, forests absorb carbon dioxide and ice fields reflect light. Seemingly small changes in temperature, light or forest cover, increasingly caused by human activity, can contribute to permanent changes in global weather patterns. An international investigation reveals nine areas enduring visible and rapid changes that could irrevocably adjust...
