CO2 Emission Levels Not Relative To Temperature

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 […]

Antarctica’s Balmy Past

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 big melt: Antarctica’s retreating ice could re-shape Earth

CAPE LEGOUPIL, ANTARCTICA: From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can’t be seen is the battle raging thousands of feet below to re-shape Earth. Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours […]

Changing climate leads to more wildfires

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 […]
