Evaluating Cloud Cover Predictions in Climate Models
A new analysis highlights progress in predictions of cloud cover from models that are part of the Coupled Model Intercomparison Project.
How Does Climate Respond to Different Forcings?
Global temperature responds in the same way to carbon dioxide as it does to methane or aerosol changes if the concept of effective radiative forcing is used to quantify the forcing strength.
Northern Europe Set for Increases in Lightning
As the climate warms across Europe, a rise in severe thunderstorms could bring a dramatic increase in related hazards, including lightning and hailstones.
Extreme Summer Heat over Europe Is Predictable Week-to-Week
Forecasts made one to a few weeks in advance, known as “subseasonal to seasonal” predictions, show more skill in predicting extreme summer heat waves over Europe than spells of normal or cold weather.
Contrails’ Climate Impact Could Triple by 2050
Contrail cirrus clouds have warmed the atmosphere more than all the carbon dioxide from planes since the dawn of aviation and will do so even more in the future.
World off Course to Meet Emissions Reduction Goals
A new energy report shows a disconnect between scientific research targets and what is happening in the energy markets.
