If climate change continues on its current trajectory, the probability that any summer between 2061 and 2080 will be warmer than the hottest on record is 80 percent across the world's land areas, according to a study by the National Center for Atmospheric Research. If greenhouse gas emissions are reduced, however, that probability drops to 41 percent, according to the study.
Scientists have successfully installed the first wave of low-cost weather stations that are designed to provide critically needed information to farmers and other residents in developing countries.

They were created by weather experts at the National Center for Atmospheric Research (NCAR) and its managing entity, the University Corporation for Atmospheric Research (UCAR).
A reduction in the amount of oxygen dissolved in the oceans due to climate change is already discernible in some parts of the world and should be evident across large regions of the oceans between 2030 and 2040, according to a new study led by the National Center for Atmospheric Research (NCAR).
A constellation of six small satellites — rocketed into space a decade ago — has made outsized contributions to our ability to forecast severe weather events, track climate change, and understand space weather.
