Climate Panel Confident Warming Is Underway (Science/Technology, 5 articles)
|
Kevin Trenberth of the Intergovernmental Panel on Climate Change was online Tuesday, Jan. 13, to discuss the Intergovernmental Panel on Climate Change report and testimony before Congress. The newest international assessment of the consequences of Earth's warming climate has concluded with "high confidence" that human-generated greenhouse gases are already triggering changes in ecosystems on land and sea across the globe. The second working group of the Intergovernmental Panel on Climate Change, which was charged with tracking the impact of global warming on specific regions and species, plans to release its final report tomorrow in Brussels. An international panel of climate scientists said yesterday that there is an overwhelming probability that human activities are warming the planet at a dangerous rate, with consequences that could soon take decades or centuries to reverse. Declaring that "warming of the climate system is unequivocal the authors said in their" Summary for Policymakers " that even in the best-case scenario, temperatures are on track to cross a threshold to an unsustainable level. That is the majority view of scientists trying to solve an equation whose variables range from greenhouse gas concentrations and the El Nino weather pattern to mosquito ecology and human cells' ability to withstand heat.

We measured how much electricity these TVs actually use when they're on (Science/Technology, 4 articles)
|
Cnet rating: 6.3 out of 10 (good) The good: Inexpensive for a 1080p LCD; solid primary color accuracy and color decoding; somewhat accurate initial color temperature; distinctive styling; well-designed remote; picture-in-picture. The bad: Poor screen uniformity and off-angle viewing; produces a somewhat light shade of black; lacks user-menu fine color temperature controls. The bottom line: Deserves consideration among budget 1080p flat-panel LCDs, but still had a hard time making hay against the better plasmas.
