“this is [...] a brush rake. Its used for clearing underbrush and debris from the forest floor that builds up and creates fuel for wild fires. Now you can stop looking stupid trying to make fun of Trump telling California to rake the forest.” | Brush rakes are attachments for the front of a wheeled or tracked machines that are used to push woody debris and large vegetation into piles. They are typically used as part of active, labor-intensive thinning, harvesting, removal, and restoration projects—not to rake large areas or clear live brush. | REFUTES |
“The amount of coral on the Great Barrier Reef is at record high levels”; those claiming the reef is threatened by climate change are alarmists | Coral reefs comprise a small, but invaluable oceanic ecosystem, because they provide protection from storms and sturges, host wildlife, are a dense source of food and have a strong economic value for local communities. The growth rate and overall health of coral reefs are very sensitive to environmental conditions, including water temperature, pH, and extreme weather events. Warming water temperatures and increasing CO2 concentrations in the ocean often cause coral bleaching events, eventually resulting in the death of large fractions of numerous coral reefs around the world. However, some coral reefs can recover from these extreme events and adapt to changing conditions if they are given enough time and the appropriate conditions. | REFUTES |

at the end of recent ice ages, the concentration of carbon dioxide in the atmosphere started to rise only after temperatures began to climb. | 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 |

A longer and warmer growing season also has an effect, Dr. Overpeck said, as plants take up more water, further reducing stream flows. | A reduction in runoff will affect the ability to irrigate crops and will reduce summer stream flows necessary to keep dams and reservoirs replenished. | SUPPORTS |
A series of just-released studies by working-level scientists prove that geological and not atmospheric forces are responsible for melting of Earth’s polar ice sheets. | The potential for major sea level rise depends mostly on a significant melting of the polar ice caps of Greenland and Antarctica, as this is where the vast majority of glacial ice is located. | NOT_ENOUGH_INFO |
‘there will not be enough nitrogen available to sustain the high carbon uptake scenarios.’ | dead leaves), direct humus accumulation, the well-developed and deep-reaching root system, the low decomposition rates of plant residues due to a high C : N ratio (carbon to nitrogen ratio), and the absence of tillage and subsequently less soil aeration are the reasons for the high carbon sequestration rates. | NOT_ENOUGH_INFO |
