Why a Hotter World Will Mean More Extinctions

Times: The end of last week saw the carbon concentrations in the atmosphere finally pass the 400-part-per-million threshold. That means carbon levels are higher now than they`ve been for at least 800,000 years, and most likely far longer. There`s nothing special per se about 400 parts per million -- other than giving all of us a change to note it in article like this one -- but it`s a reminder that we are headed very fast into a very uncertain future. Parts per million and global temperature change,...

Earths core is much hotter than previously thought hotter than the surface of the Sun
2013-04-26 18:20:51| Extremetech
Using a delicious combination of particle accelerators, X-rays, high-intensity lasers, diamonds, and iron atoms, scientists have worked out that the inner core of the Earth is actually 6,000 degrees Celsius -- some 1,000 degrees hotter than the previous scientific estimate. This new data could generate repercussions in the fields of geophysics, seismology, geodynamics, and other Earth-oriented scientific disciplines.
Greenhouse gases make high temps hotter in China

Associated Press: China, the world's largest producer of carbon dioxide, is directly feeling the man-made heat of global warming, scientists conclude in the first study to link the burning of fossil fuels to one country's rise in its daily temperature spikes. China emits more of the greenhouse gas than the next two biggest carbon polluters -- the U.S. and India -- combined. And its emissions keep soaring by about 10 percent per year. While other studies have linked averaged-out temperature increases in China...
Insect pests more plentiful in hotter parts of city than in cooler areas

ScienceDaily: Higher temperatures in cities can be a key driver of insect pest outbreaks on trees in urban areas, according to research published March 27 in the open access journal PLOS ONE by Emily Meineke from North Carolina State University and colleagues from other institutions. The researchers found that a scale insect that exclusively feeds on oak trees was 13 times more abundant on willow oaks in the hottest parts of the city of Raleigh, North Carolina than in cooler areas of the same city, even when...
Scientists Say Earth Hotter Now Than Most of Past 11,300 Years
2013-03-07 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: The Earth is warmer now than during 70 to 80 percent of the time stretching back to the last Ice Age, according to researchers from Oregon State and Harvard universities who studied data from more than 73 global sites. The findings also show that temperature-change rates are accelerating, Shaun Marcott, a scientist at Oregon State in Corvallis and one of the papers authors, said yesterday in an interview. The study was published today by the journal Science. The research is the longest global...
