What is hail or a hailstone? Hail is a form of precipitation that occurs when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere where they freeze into balls of ice. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. How does hail form? Hailstones grow by colliding with supercooled […]

When the atmosphere had much higher levels of carbon dioxide, Antarctica was as warm as California. New research has revealed that 430 million to 50 million years ago, temperatures on the frozen continent averaged 57 degrees Fahrenheit, with part of the surrounding Pacific Ocean reaching up to 72 degrees. In this ancient era, known as the Eocene epoch, carbon dioxide […]

The amount of CO2 is increasing all the time – we just passed a landmark 400 parts per million concentration of atmospheric CO2, up from around 280ppm before the industrial revolution. That’s a 42.8% increase. A tiny amount of CO2 and other greenhouse gases, like methane and water vapor, keep the Earth’s surface 30°Celsius (54°F) warmer than it would be […]

New South Wales and southern Queensland are going to be suffering from warmer weather and less rain than in the past. This temperature change is called “sudden stratospheric warming.” It happens when the air above the South Pole starts to warm up rapidly. Predictions are that the warming of Antarctic will likely be higher than a previous record high in […]

Historic drought: Broiling heat baked much of the U.S. heartland this week, as the nation’s worst drought in more than 50 years devastated corn, soy, and other vital crops. More than 1,000 counties in 26 states have been declared natural disaster areas and 38 percent of the nation’s corn crop is in danger of withering in the field, the U.S. […]

Western Antarctica is heating up faster than almost any other region on earth, increasing the risk that a huge ice sheet there could collapse and cause a drastic rise in sea levels. That’s the alarming conclusion of climate researchers who used data from a remote weather station combined with other temperature readings on the continent to show that West Antarctica […]

The monster forest fires rampaging across the Western states may soon be the norm, thanks to climate change. New research indicates that as rainfall diminishes and vegetation dries out on a warmer planet, the West is headed into a more fire-prone future,” wildfire specialist Max Moritz tells the Los Angeles Times. After studying satellite imaging of fires and data from […]

Climate change appears to be affecting the jet stream, altering the weather patterns over the U.S. so that regions can get “stuck” in extreme weather for weeks, a new study has found. The jet stream is the fast-moving, high-altitude air current that shuttles weather from west to east over North America and Europe. But the pronounced warming of the Arctic—where […]
