It’s Not Just The Heat, It’s The Carbon

Rep. Steve Kagan, MD (D-Wis.) hosted a conference of immunologists, and their first order of business was to tell reporters that climate change is and has been harming human health.
Paul Epstein, MD, MPH, Center for Health & the Global Environment, Harvard Medical School, said that asthma rates have quadrupled since 1980. Much of this is due to CO2. The greenhouse gas stimulates plants, including weeds, to grow more prolifically, and through longer seasons. Not only does this mean more pollen, but the pollen itself is more allergenic. In fact, he said, poison ivy is becoming stronger as well, leading to more severe reactions.
Biofuels aren’t helping; diesel particles in the air act as carriers for pollen and other allergens.
The ozone produced by combustion engines, while it might be helpful in the upper atmosphere, irritates the lungs.
Finally, the geographic range of allergenic weeds is expanding.
CO2 means, more and nastier pollen, for longer periods, in more places, he concluded.
He then addressed malaria, which is seen higher and higher up the mountains of endemic areas, more subtly in more geographic areas over time, and, less subtly, for longer seasons each year. Malaria is following the warm climate farther and farther from the equator.
Other ills following this pattern include Dengue Fever and Yellow Fever. In fact, a great many of the diseases you never want to have are spreading their range, he said.
Jeffrey Demain, MD, FAAAAI, Allergy & Immunology Center of Alaska, said insects also are more numerous for longer seasons, leading to more bites, stings, infections, and even deaths.
“We have 12 villages that are imperiled; they’re falling into the sea.” Permafrost roads are only passable for half as many days a year as formerly, limiting opportunities for subsistence hunters.
“The question,” he said, “is whether Alaska is an aberration, or a window (to the future).”
David Peden, MD, FAAAAI, Center for Environmental Medicine Asthma & Lung Biology, said that ozone and pollution don’t just irritate the lungs, but leave them more irritable to all allergens for days after exposure. The number of respiratory emergency department visits dropped sharply when traffic patterns in Atlanta were altered to accommodate Olympic athletes in 1996.
Dr. Kagen said, “there can be no doubt that climate change is taking place at a more rapid rate than anyone had expected.” He presented supporting data at the conference.
All four of the physicians agreed that carbon emissions were doing unequivocal harm to human health.

Actress Mandy Moore Joins UN Drive To Fight Malaria
Mandy Moore is joining a long list of celebrities who have helped raise money to try and prevent the spread of malaria in Africa and other regions around the world.
Moore, a 26-year-old New Hampshire-born singer/songwriter/actress, has been involved with fighting malaria for several years. She has also helped raise money and generate awareness for leukemia and lymphoma.
In a conference call with reporters on Friday, Moore announced that she is currently in the Central African Republic (CAR) this week, teaming up with the UN Foundation to help raise funds for net beds that can be used to prevent mosquito bites, which are the primary cause of malaria.
“We can prevent this disease, we can save lives,” she said. “We just need everyone’s involvement…a 10 dollar donation truly does save lives.”
The UN Foundation, a charity that promotes United Nations initiatives, started its ‘Nothing But Nets’ campaign in 2006 in an effort to help distribute life-saving nets to those in need. The incesticide-treated nets cost $10 dollars per, and if used properly can lower the spread of malaria by up to 90% in high-risk areas. Foundation studies show that one net bed generally lasts a family up to four years.
According to statistics compiled by the World Health Organization, roughly 250 million cases of malaria are reported each year, resulting in around one million deaths annually. 85% of these deaths occur in sub-Saharan Africa, with mostly young children under the age of five falling victim.
Moore said 400,000 more nets are needed in CAR by the end of the year in order to supply every household in the country.
