U.N. scientists aim to pitch climate case to widest audience

By Environment Correspondent Alister Doyle STOCKHOLM (Reuters) - A U.N. panel of global climate scientists were set to work through Thursday night to ensure that their strongest case yet for man-made global warming would make sense to the widest possible audience. Drafts show that the Intergovernmental Panel on Climate Change (IPCC) is set to pronounce that most of the warming of the Earth's surface since the 1950s is "extremely likely" -- at least 95 percent probable -- to be man-made. At its last meeting in 2007, it put the probability at 90 percent, and in 2001 it was 66 percent. ...

Fossil fish find in China fills in evolutionary picture

By Tim Hurd SYDNEY (Reuters) - An international team of scientists in China has discovered what may be the earliest known creature with a distinct face, a 419 million-year-old fish that could be a missing link in the development of vertebrates. The fossil find in China's Xiaoxiang Reservoir, reported by the journal "Nature" on Thursday, is the most primitive vertebrate discovered with a modern jaw, including a dentary bone found in humans. " finally solves an age-old problem about the origin of modern fishes," said John Long, a professor in palaeontology at Flinders University in Adelaide. ...

U.N. panel blames mankind more clearly for warming

STOCKHOLM (Reuters) - Top climate scientists blamed mankind more clearly than ever as the main cause of global warming in a report on Friday meant to guide governments in dealing with rising temperatures, delegates said.

Scientists say more certain mankind causes global warming

By Alister Doyle and Simon Johnson OSLO (Reuters) - Leading climate scientists said on Friday they were more certain than ever before that mankind was the main culprit for global warming and warned the impact of greenhouse gas emissions would linger for centuries. A report, by the Intergovernmental Panel on Climate Change (IPCC), played down the fact temperatures have risen more slowly in the past 15 years, saying there were substantial natural variations that masked a long-term warming trend. ...

Goosefish Lays Billowy Veil Holding 1 Million Eggs
