Study Shows The Great Barrier Reef Is Growing Quickly | As the planet’s largest coral reef ecosystem, the Great Barrier Reef is home to thousands of marine species and is a major contributor to the Australian economy. However, its size and status cannot protect it from the impacts of climate change. The reef remains vulnerable to ocean warming, more intense storms, predator outbreaks, and other stressors caused by climate change. Warmer ocean temperatures can cause coral to “bleach”, a process in which they dispel symbiotic algae living within their tissue, which leaves them weaker and more susceptible to death. Under the right conditions, bleached coral can recover, but a single, low-disturbance year does not provide scientists enough data to make judgements on overall reef health, as short-term recovery can quickly be reversed. | REFUTES |

While changes in cloud cover & aerosols lead to more sunlight hitting the surface, this can be compensated by the cooling effect on the atmosphere due to fewer clouds trapping less warmth and fewer absorbing aerosols absorbing less sunlight. | The particles reflect and absorb sunlight, less sun rays reach Earth surface layers, thus resulting in cooler water and land surface temperatures, and also less cloud formation, subsequently dampening the development of hurricanes. | NOT_ENOUGH_INFO |
