Greenhouse gases were the main driver of climate throughout the warmest period of the past 66 million years, providing insight into the drivers behind long-term climate change.

Hurricane season didn't officially start until June 1, but Subtropical Storm Alberto made an appearance early, causing more than $50 million in damage as it made its way inland and up the coast in late May. Twelve people — seven in Cuba and five in the U.S. — died as Alberto's fallout included flooding, landslides, tornados and mudslides.  

A study led by the University of Southampton has shown the greening up of vegetation prior to the rainy season in Africa is more widespread than previously understood.

When the Global Precipitation Measurement mission or GPM core satellite passed over the Northwestern Pacific Ocean, it saw very heavy rainfall occurring in one part of Tropical Storm Prapiroon.

Infrared NASA satellite imagery provided cloud top temperatures of thunderstorms that make up Tropical Storm Emilia. Comparing those NASA temperature readings with another satellite’s data obtained the following day, forecasters determined that Emilia had strengthened.

Climate projections indicate more warming will occur in the Northeast than other sections of the United States, and that has implications for corn crops and dairy farms in the region by 2050, researchers warn.

Climate change predictions are not taking account of the full range of possible effects of rising carbon dioxide levels, researchers say.

Carbon dioxide emissions from human activities must approach zero within several decades to avoid risking grave damage from the effects of climate change.  This will require creativity and innovation, because some types of industrial sources of atmospheric carbon lack affordable emissions-free substitutes, according to a new paper in Science from team of experts led by University of California Irvine’s Steven Davis and Carnegie’s Ken Caldeira.

The Global Precipitation Measurement mission or GPM core satellite passed over Tropical Depression Six-E in the Eastern Pacific Ocean and found heavy rainfall occurring in two areas. Shortly after GPM passed overhead, the depression strengthened into Tropical Storm Emilia.

NASA's Aqua satellite passed over the Northwestern Pacific Ocean early on June 28 and caught an image of newly formed Tropical Depression 09W.
