Plugging the Leaks in Climate Models
Independent quality controls for climate models are crucial for the quality of future climate change predictions. Not all models are equally good and should be utilized in climate impact studies for such things as crop yield and hydrology that are produced for far-reaching decision-making.

Climate change may be affecting the jet stream
A new study provides evidence that climate change may be affecting the northern hemisphere jet stream, which appears to be moving north and slowing down. The slowing of the jet stream could cause weather patterns to remain in place for longer, resulting in prolonged heat waves or cold snaps.
