BRUSSELS, Belgium (CP) - Global warming's effects on daily life are here already, still more pesky than catastrophic. But a new authoritative scientific report says that when the Earth gets a few degrees hotter, inconvenience will give way to danger, death and extinction of species.
The poorest parts of the world, especially Africa and Asia, will be hit hardest, says the summary from the Intergovernmental Panel on Climate Change, issued Friday after a long, contentious editing session.
It is a message the authors of the report pounded home Friday before unveiling the 23-page document. The summary was the first part released of the full 1,572 page document written and reviewed by 441 scientists.
"Don't be poor in a hot country, don't live in hurricane alley, watch out about being on the coasts or in the Arctic, and it's a bad idea to be on high mountains with glaciers melting," Stanford University scientist Stephen Schneider, an author of the study, told The Associated Press.
This document, the second of four reports, tries to explain how global warming is changing life on Earth.
Even though some of the scientists' direst prose was toned down or lost, the panel's report was gloomy - with a bit of hope at the end.
Africa by 2020 is looking at an additional 75 to 250 million people going thirsty because of climate change, the report said. Deadly diarrhea diseases "primarily associated with floods and droughts are expected to rise" in Asia because of global warming, the report said.
But many changes to the report, made during a meeting of government negotiators from more than 120 countries, play down some of the dangers forecast by the authors - all eminent scientists.
"Many millions more people are projected to be flooded every year due to sea-level rise by the 2080s," the report said. "The numbers affected will be the largest in the mega-deltas of Asia and Africa while small islands are especially vulnerable."
The draft version proposed by scientists had said "hundreds of millions" of people would be vulnerable to flooding, rather than "many millions."
The final report also dropped any mention of the possibility that up to 120 million people are at risk of hunger because of global warming, referring instead to "complex localized negative impacts on small holders, subsidence farmers and fishers."
The first few degrees increase in global temperature will actually increase global food supply, but then it will plummet, according to the report.
An increase of just about one degree Celsius could mean "up to 30 per cent of the species at increasing risk of extinction," the report said. If the globe heats a few more degrees, that changes to "significant extinctions around the globe."
"The poorest of the poor in the world - and this includes poor people in prosperous societies - are going to be the worst hit," said Rajendra Pachauri, chairman of the climate change panel. "People who are poor are least able to adapt to climate change."
But even rich countries, such as the United States, say the report tells them what to watch for.
The Canadian Red Cross said Friday the report confirmed its worst fears. It called on Canadians to dramatically increase their investment in disaster preparedness to help vulnerable communities mitigate against the consequences of global warming.
Reacting to the report, Liberal Leader Stephane Dion called on Prime Minister Stephen Harper to endorse the revised version of the Clean Air Act including its plan to have a carbon budget for Canada that will help the country honour its Kyoto commitments.
The head of the U.S. delegation, White House associate science adviser Sharon Hays, said a key message she is taking from Brussels to Washington is "that these projected impacts are expected to get more pronounced at higher temperatures. ... Not all projected impacts are negative."
Schneider said a main message is not just what will happen, but what already has started: melting glaciers, stronger hurricanes, deadlier heat waves, and disappearing or moving species.
It all can be traced directly to greenhouse gases from the burning of fossil fuels.
"There is a discernible human influence on these changes" that are already occurring as threats to species, flooding, extreme events such as heat waves and hurricanes, said NASA scientist Cynthia Rosenzweig, a lead author on the chapter detailing what has happened.
Martin Parry, who conducted the closed-door negotiations, said with 29,000 sets of data from every continent, including Antarctica, the report firmly and finally established "a man-made climate signal coming through on plants, water and ice."
But many of the worst effects are not locked into the future, the report said in its final pages. Humans can build better structures, adapt to future global warming threats and can stave off many by reducing greenhouse gas emissions, scientists said.
"There are things that can be done now, but it's much better if it can be done now rather than later," said scientist and report author David Karoly of the University of Oklahoma.
And because carbon dioxide stays in the air for nearly a century, it will be decades before society sees that changes make a difference on global warming effects, scientists said.
"We can fix this," by investing a small part of the world's economic growth rate, said Schneider. "It's trillions of dollars, but it's a very trivial thing."
