Study: 'Warm ice age' changed climate cycles

Approximately 700,000 years ago, a "warm ice age" permanently changed the climate cycles on Earth. Contemporaneous with this exceptionally warm and moist period, the polar glaciers greatly expanded. A European research team ...

Tornado-spawning storms may get worse due to warming

America will probably get more killer tornado- and hail-spawning supercells as the world warms, according to a new study that also warns the lethal storms will edge eastward to strike more frequently in the more populous ...

Ocean surface tipping point could accelerate climate change

The oceans help to limit global warming by soaking up carbon dioxide emissions. But scientists have discovered that intense warming in the future could lessen that ability, leading to even more severe warming.

Can clay capture carbon dioxide?

The atmospheric level of carbon dioxide—a gas that is great at trapping heat, contributing to climate change—is almost double what it was prior to the Industrial Revolution, yet it only constitutes 0.0415% of the air ...
