problem associated with "cherry picking" information. The cartoon tree "screams" when it absorbs CO2 in the spring, which can leave a negative impression when in fact the trees want and need CO2. Pas ...

to poor or nonexistent grazing land. The South Dakota State Climatologist reported that corn is in tasseling stage now; under drought stress, this can lead to an 8% yield loss per day, which is the hi ...

or temperature events occur, they often times can be traced to a highly unusual setup in the atmosphere. In the past, I have touched on these atmospheric traffic jams when they caused melt events in G ...

For example, according to NOAA's 2021 Arctic Report Card, 2021 spring snow cover extent in the Eurasian Arctic was well below average in May (5th lowest on record) and June (3rd lowest). In the North ...

As the climate system continues responding to the heat-trapping gases we have added to the atmosphere, temperatures will change at different rates in different regions. Images of projected future clim ...
