Climate change skeptics uniting in Springfield, Mo.
Boyer said the conference is a result of his decision to push back against those he considers "global warming alarmists" and give skeptics a much-needed public platform."I think the case for this side is so much stronger, but you don't see much about it in the paper and television," Boyer said.
Most scientists believe that Earth is warming due to the buildup of heat-trapping gases in the atmosphere. Consequently, many have predicted the world will experience more flooding, droughts and other cataclysmic events unless greenhouse gas emissions are reduced. Two years ago, members of the Nobel Prize-winning United Nations Intergovernmental Panel on Climate Change concluded with near certainty that Earth's most recent warming cycle was the result of human activities.While there is disagreement among scientists about the extent and pace of climate change and what to do about it, many have backed the IPCC's conclusions."There's not much debate within the majority of the scientific community," said Don Wuebbles, an atmospheric scientist with the University of Illinois at Urbana-Champaign who served on the IPCC and wrote some of its early assessments. "Sure, an interesting point will come up and we'll poke at it, but that's our life."Some skeptics, however, continue to challenge the basic science, often pointing to solar activity or swings in ocean cycles as the likely culprits behind current climate shifts.They are vehemently opposed to the climate change legislation that's expected to go to the Senate for a vote this fall that would place limits on greenhouse gas emissions.Dan Lashoff, director of the Natural Resources Defense Council's Climate Center, said political ideology — not science — seems to be the common thread among the Springfield conference speakers, some of whom are slated to talk about climate change legislation."I think most opponents of this legislation have moved past the debate over science," Lashoff said. "Most of the organized opposition is focusing on the economics. But some of these guys, I guess, just won't give up."One of the key voices in the skeptic community who doesn't seem remotely ready to give up is Morano, who runs ClimateDepot.com, a skeptic website and news service.He is perhaps best known for compiling a Senate committee report that contains the names of more than 700 international scientists he describes as climate change dissenters. Environmental advocates have questioned the credentials of some of the people on that list.During his speech in Springfield, Morano says, he'll challenge the notion that there's a consensus among scientists about climate change. Instead, the number of skeptics — among scientists and the general public — "is skyrocketing," he said."This is a grass-roots rebellion, and the Springfield conference is a great example," Morano said. Boyer said last week that about 120 people have signed up for the conference, and he's hoping about double that number show up. He said he has been contacted by several area teachers planning to bring students to the event being held at the Ramada Oasis Hotel.The conference is a test of sorts. If there's a good turnout and the Senate fails to take up the legislation, Boyer said, he might organize additional conferences, with Dallas likely being the next host city.Boyer emphasized that his consulting company is paying for the conference and that his views about climate change shouldn't be construed as a position of the state Air Conservation Commission, which develops Missouri's clean air policies. Three members of the air commission either declined to discuss their personal views about climate change or didn't return phone calls. Another, Jack Baker, said he was undecided about what to do about climate change. "I guess we really need to be careful when it comes to the environment," he said. "We don't want to destroy it, but we don't want to hurt our economy, either."Boyer, a former top official in the Springfield-Greene County Health Department, was appointed to the commission by former Gov. Matt Blunt in March 2008. Last fall, he rankled some environmentalists when he made a presentation at a commission meeting that laid out a case for why the state's odor regulations shouldn't be changed. Boyer argued that animal agriculture was under attack and that "animal rights activists, anti-capitalists, radical environmentalists, activist judges, vegetarians, vegans and locavores had piled on."Nonetheless, Boyer says he invites members of Missouri's environmental groups to attend the conference, which he says welcomes dissenting opinions.Kathleen Logan Smith, director of the Missouri Coalition for the Environment, said she was not aware of any coalition members planning to attend the conference."When Missouri is trying to position itself with the science and technology sector, it doesn't help to have anti-science folks in such prominent positions," Smith said of Boyer. "It doesn't do much for our reputation."

State of India's environment sickening: report
The third official report on the state of India's environment, published after a gap of eight years and released by Minister of State for Environment and Forests Jairam Ramesh on Tuesday, has only one word of cheer: it says India is using 75 percent of the water it can use, and it has "just enough for the future if it is careful".
The report, prepared by NGO Development Alternatives under the aegis of the ministry, says 45 percent of India's land area is degraded due to erosion, soil acidity, alkalinity and salinity, waterlogging and wind erosion.
It says the prime causes of land degradation are deforestation, unsustainable farming, mining and excessive groundwater extraction.
On the bright side, the report shows how over two-thirds of the degraded 147 million hectares can be regenerated quite easily, and points out that India's forest cover is gradually increasing.
Ramesh said it would be unrealistic to expect that India's area under forests would go above the current 21 percent, given the competing demands for land. "Our plan is to have all this 21 percent as high and medium density forests within the next 10 years," he said. Currently, only two percent of India is under high density forest cover, while medium density forests cover about 10 percent of the land.
Presenting the salient features of the report to the media, Development Alternatives President (Development Enterprises) George C Varughese said one of its most worrisome findings was that the level of respirable suspended particulate matter--the small pieces of soot and dust that get inside the lungs--had gone up in all the 50 cities across India studied by the All India Institute of Medical Sciences and the Central Pollution Control Board.
"In these 50 cities, with their population of 110 million, the public health damage costs due to this was estimated at Rs.15,000 crore in 2004," Varughese said.
The main causes of urban air pollution were vehicles and factories, he pointed out, appealing for a major boost to public transport.
While India still had some cushion when it came to water use, this scarce resource would have to be managed very carefully, the report says. It identifies lack of proper pricing of water for domestic usage, poor sanitation, unregulated extraction of groundwater by industry, discharge of toxic and organic wastewater by factories, inefficient irrigation and overuse of chemical fertilisers and pesticides as the main causes of water problems in the country.
While India remains one of the world's 17 "megadiverse" countries in terms of the number of species it houses, 10 percent of its wild flora and fauna are on the threatened list, Varughese pointed out. The main causes, according to the report, were habitat destruction, poaching, invasive species, overexploitation, pollution and climate change.
The report points out that while India contributes only about five percent of the world's greenhouse gas emissions that are leading to climate change, about 700 million Indians directly face the threat of global warming today, as it affects farming, makes droughts, floods and storms more frequent and more severe and is raising the sea level.
In the section on urbanisation, the report points out that 20 to 40 percent of people living in cities are in slums. Varughese said there were good projects to upgrade their lives and improve the environment at the same time, but the problem was that most of the money from schemes like the Jawaharlal Nehru National Urban Renewal Mission was taken away by the big cities, "while the major problem is in about 4,000 small and medium towns".
Green and confused: What happens to old satellites?
Q.On the anniversary of the Apollo Moon landings, my eight-year-old son asked what happens to the old satellites and other debris in space. Will they eventually fall to Earth?
Your son has put his finger on what is becoming quite an environmental problem. First, tell him not to worry: he doesn’t have to go round with a hard hat on for fear of a wayward satellite flattening him. Most space debris, if it falls back to Earth, burns up as it re-enters the atmosphere.
However, there is a great deal of junk out there, zooming along at speeds of up to 25,000mph. At such a velocity, a mere flake of paint can do considerable damage to a satellite. Nasa frequently has to mend windows on its spacecraft because of penetration by minuscule flying objects.
No one is sure of the exact amount that has accumulated since the launch of the first satellite, the Soviet, in 1957, but over the years, millions of pieces of debris from space missions and satellites have contributed to what has become a revolving scrapyard way above our heads. Objects range from jettisoned spacecraft parts to tiny fragments of fuel and urine.
A United Nations body called the Inter-Agency Debris Co-ordination Committee uses sophisticated radar and monitoring equipment to track the debris and is able to detect objects (about 9,000) bigger than a tennis ball. Smaller objects can’t be tracked but are growing in number. One of the problems is that as these objects collide or break up, more debris is created. A discarded launch arm can wipe out a multimillion-dollar satellite. A bolt dropped during a space station repair could puncture the skin of a spacecraft and cause a catastrophe.
On occasions a space launch has had to be delayed until scientists were certain that the rocket would enter a “junk-free” zone. Now engineers are looking for ways to vaccuum up the debris before disaster strikes. It’s a bit like the mounting pile of rubbish deposited on Everest by climbers — the more we explore, the more junk is amassed. Man leaves an environmental footprint everywhere, even in space.
