Earth's soils could play key role in locking away greenhouse gases

The world’s soils could store an extra 8 billion tonnes of greenhouse gases, helping to limit the impacts of climate change, research suggests. Adopting the latest technologies and sustainable land use practices on a global scale could allow more emissions to be stored in farmla

Ocean temperatures predict U.S. heat waves

<!– –> The formation of a distinct pattern of sea surface temperatures in the middle of the North Pacific Ocean can predict an increased chance of summer heat waves in the eastern half of the U.S. up to 50 days in advance. The pattern is a contrast of warmer-than-ave
