Carbon Capture: A Tough Nut to Crack
Populations grow, emissions increase, global temperatures continue to rise. What to do?
Emission cap-and-trade schemes and renewable energy alone likely won’t be able to bend the carbon curve — the term climate-change experts like to use to describe a reduction in greenhouse gas emissions.
For that reason, governments and companies increasingly are looking for new and unconventional [...]
COP-16 Renews Hope for Global Climate Treaty
The world may finally be on its way toward a legally binding treaty that includes all major greenhouse gas emitters and compensates nations most vulnerable to climate change.
Many environmental groups and governments from all corners of the world seem to concur: Agreements reached at the U.N.-led climate summit in Cancún, Mexico, set countries on a [...]
“Substantial” Actions Show U.S. Commitment to Climate Change
More than 190 nations, many with widely different needs and political realities at home, are trying to unite around a common global agenda at the climate conference in Mexico — not an easy task.
Nearly a week into the meetings, the U.S. delegation at COP-16 maintains that the United States stands by its commitments from last [...]
Cancún Climate Summit Can Yield Successes, U.S. Negotiator Says
Nations won’t be able to agree on a legally binding climate treaty this year, but they can make progress in a number of key areas that could — “maybe” — lead to a final deal next year, the U.S. chief climate negotiator said.
“What we’re seeking now in Cancún is a balanced package of decisions,” [...]
Individual Action, Global Impact: Your Questions Answered
Scientists agree that a rise in greenhouse gases due to human activity is disrupting climate around the world. Climate is changing unevenly and likely more rapidly than many countries’ capacity to adapt.
Just as the burning of fossil fuels in one nation affects climate around the globe, reducing carbon dioxide emissions in one part of the [...]
Ocean “Dead Zones” Spreading Along U.S. Coasts
Runoff from farms, gardens made worse by changing climate, new study says
Pollution, coupled with stresses from climate change, is making U.S. coastal waters sicker by the year, new research by leading U.S. environmental and scientific agencies concludes.
So-called “dead zones,” caused primarily by runoff from agricultural fertilizers, sewage and landscaping, are occurring 30 times more [...]
Global Temperature Records Start with 10,200 Volunteers
Long-term measurements are critical to understanding climate change
For 120 years, a global network of land-based weather stations has monitored Earth’s surface temperature. In the United States, steadfast volunteers have tended these stations since 1890, measuring daily temperature, rain and snow depth to support weather forecasts and, over time, monitor a changing climate.
The National Weather Service’s [...]
U.N. Program Targets Climate Change and Health in Seven Countries
Nations seek help with problems that will worsen as climate changes
As global temperature climbs, storms intensify and small island states lose their coastal areas to the rising sea, a four-year project is starting up in seven countries to help the most vulnerable populations adapt to the health impacts of climate change.
The $4.5 million pilot effort, [...]
Health Day Focuses on Helping Cities Weather Climate Change
Urban health focus for millions vulnerable to rising temperatures, seas
The goal of World Health Day 2010, themed “1,000 Cities, 1,000 Lives,” is to raise awareness about public health in urban areas. The message is critically important to hundreds of millions of city dwellers who already may be experiencing the health-threatening effects of climate [...]
21st Century Agriculture
Humanity’s longest struggle has been the ongoing battle, waged with different weapons on different fronts, adequately to feed itself. The British scholar Thomas Malthus (1766–1834) doubted humanity’s chances. Writing in 1798, he concluded that “the period when the number of men surpass their means of subsistence has long since arrived.” The result, Malthus predicted, would [...]
