This is not up for debate, despite what your uncle may say at holiday dinner. In fact, the last time atmospheric carbon dioxide amounts were this high was more than 3 million years ago, during the Mid-Pliocene Warm Period, when global surface temperature was 4.5–7.2 degrees Fahrenheit (2.5–4 degrees Celsius) warmer than … When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Heavy rain is also more common because of climate change. Sadly, the catastrophic events that are unfolding in Australia are a prelude to the future. Climate change is exacerbating catastrophic bushfire conditions. The American pika, for example, is a small mammal that lives in cool mountainous areas in western North America—in fact, it can die when exposed to temperatures warmer than 78˚F.So as the mountain climate heats up, the pika climbs the slopes in search of cooler habitat.

What’s the link between climate change and drought? FACT: 99.84% of the land in the state of California is suffering from drought. This corresponds to other indications such as: Melting ice caps; Reduced sea ice; Warmer oceans; Migration of temperature-sensitive species Human activities (primarily greenhouse gas emissions) are the primary cause. Climate scientists are underpaid — or not paid at all — for their work. The kind of heavy one-day rain that 150 years ago would have only happened once every ten years is now happening 1.3 times every ten years. Federal climate change reports are credible because they are written by scientists, not politicians.
