Ice core samples from Antarctica show a massive rise in trapped co2. Historical levels have been 180 to 300 ppm. Current levels are 380 ppm. At 440 ppm there could be a tipping point at which climate change really takes off.
Isotope samples showed the co2 was from fossil fuel sources.
A White House spokesperson said the core samples hated freedom and loved the terrorists, reiterating their stance that the cost to business to remediate co2 buildup would be excessive. When asked to further explain the relationship between climate change and terrorism, and how, say, businesses in Manhattan would benefit if the streets were underwater, the spokesperson stated the president is committed to bringing democracy to Antarctica despite those who would force our great corporations like ExxonMobil and Halliburton to not make bloated windfall profits.
