However, it is unable to explain the long term warming trend over the past few decades. | The New York Times highlighted their finding that the 20th century had been the warmest century in 600 years, quoting Mann saying that "Our conclusion was that the warming of the past few decades appears to be closely tied to emission of greenhouse gases by humans and not any of the natural factors". | REFUTES |
In the process, the cows will emit much greenhouse gas, and they will consume far more calories in beans than they will yield in meat, meaning far more clearcutting of forests to farm cattle feed than would be necessary if the beans above were simply eaten by people.” | Agriculture contributes to climate change by anthropogenic emissions of greenhouse gases, and by the conversion of non-agricultural land such as forest for agricultural use. | SUPPORTS |

The winds around the continent seem to be strengthening, stirring the ocean and bringing up a layer of warmer water that has most likely been there for centuries. | Within the Atlantic Ocean vertical wind shear is increased, which inhibits tropical cyclone genesis and intensification, by causing the westerly winds in the atmosphere to be stronger. | SUPPORTS |

Unlike the simple example of positive feedback we learned in high school, the increase from every round of feedback gets smaller and smaller, in the case of the enhanced greenhouse effect. | This releases more stored carbon into the atmosphere than the carbon cycle can naturally re-absorb, as well as reducing the overall forest area on the planet, creating a positive feedback loop. | NOT_ENOUGH_INFO |

Skeptics have long pointed to ice gain in the Southern Hemisphere as evidence climate change wasn’t occurring, but scientists warned that it was caused by natural variations and circulations in the atmosphere. | In a NASA report published in January 2013, Hansen and Sato noted "the 5-year mean global temperature has been flat for a decade, which we interpret as a combination of natural variability and a slowdown in the growth rate of the net climate forcing." | SUPPORTS |
a distressing number of the [West coast] fires are not accidents, and willful arson is the cause. | Recent wildfires on the West Coast have been ignited by a number of sources, including lightning, power lines, and even a smoke machine at a party. Their severity is the result of strong winds and intense drought driven by a dry summer and record warmth, which is part of an ongoing human-caused warming trend. | REFUTES |
