(Newser) – Efforts to eradicate malaria are going to be hit hard by rising temperatures that open up new altitudes to the mosquitoes that carry the disease, researchers warn. Both mosquitoes and the malaria parasite struggle in chillier temperatures, and a new study has found that the disease climbs to higher elevations in warmer years, the BBC reports. In areas like the highlands of Colombia and Ethiopia, people have never been exposed to malaria, making them especially vulnerable to the spread of the disease.

"We have estimated that, based on the distribution of malaria with altitude, a 1C rise in temperature could lead to an additional three million cases in under-15-year-olds per year," one of the researchers warns. Malaria infects more than 200 million people per year and kills around 600,000 of them, mainly children in Africa. But climate isn't the only factor at work in its spread, with the biggest advances in malaria control coming alongside efforts to combat poverty, Time notes.

How many million people have been murder by Rachel Carson and her Silent Spring BS. Millions of people die to support a false cause backed by bad science to eliminate DDT. Since manmade global warming has been disproven we can be assured that the environmental loons who hate people will use this to get more stupid laws passed. Bring back DDT and eliminate the malaria mosquito.

Point A: People like John3:16 have never read a scientific study on the subject and are so ignorant they disagree based on what they can see from their window. Point B: Republicans do not agree with global warming because liberals have made such a big deal about it. Republicans would rather deny to their dying day than admit they were wrong. It's all a game to them. If a republican was the first to make it a big deal they would embrace the F**K out of it.

The United States is less than 2% of the surface area of the earth. Whether or not it was cold in some minuscule portion of that couldn't be less relevant. Scientists, the people who invented e-beam lithography, lasers, and MRI machines are telling you that there is 95% agreement that we are in what could very well be the overwhelmingly largest disaster to ever hit man, possibly wiping out half of us and thrusting us into the dark ages. If there is 95% agreement on this, and consider global warming unequivocal, shouldn't we consider that they might possibly be right?
