Recent research also indicates that the quantity of fossil fuels staying in the atmosphere is much less than previously thought. | While the lifetime of atmospheric methane is relatively short when compared to carbon dioxide, with a half-life of about 7 years, it is more efficient at trapping heat in the atmosphere, so that a given quantity of methane has 84 times the global-warming potential of carbon dioxide over a 20-year period and 28 times over a 100-year period. | NOT_ENOUGH_INFO |
The ocean is absorbing massive amounts of CO2, and is becoming more acidic as a result. | Although the natural absorption of CO 2 by the world's oceans helps mitigate the climatic effects of anthropogenic emissions of CO 2, it is believed that the resulting decrease in pH will have negative consequences, primarily for oceanic calcifying organisms. | SUPPORTS |

Increased CO2 makes more water vapor, a greenhouse gas which amplifies warming | Increases in atmospheric concentrations of CO 2 and other long-lived greenhouse gases such as methane, nitrous oxide and ozone have correspondingly strengthened their absorption and emission of infrared radiation, causing the rise in average global temperature since the mid-20th century. | NOT_ENOUGH_INFO |

The jet stream controls broad weather patterns, such as high-pressure and low-pressure systems. | A polar cyclone is a low-pressure weather system, usually spanning 1,000 kilometres (620 mi) to 2,000 kilometres (1,200 mi), in which the air circulates in a counterclockwise direction in the northern hemisphere, and a clockwise direction in the southern hemisphere. | SUPPORTS |

Greenhouse gases emitted into the ocean are causing more holes in the ozone layer … “the ozone layer has holes in it causing global temperature to rise” | It is a common misconception that Global Warming would be due to holes in the ozone layer caused by Greenhouse gases (GHG).
