When Rick Ostfeld gets bitten by a tick, he knows right away. After decades studying tick-borne diseases as an ecologist at the Cary Institute of Ecosystem Studies in Millbrook, New York, Ostfeld has been bitten more than 100 times, and his body now reacts to tick saliva with an intense burning sensation. He’s an exception. Most people don’t even notice that they’ve been bitten until after the pest has had time to suck up a blood meal and transfer any infections it has circulating in its spit.

Researchers using satellite imaging have found much greater than expected deforestation since 2000 in the highlands of Southeast Asia, a critically important world ecosystem. The findings are important because they raise questions about key assumptions made in projections of global climate change as well as concerns about environmental conditions in Southeast Asia in the future.

One of Canada’s largest pension fund’s continued and increasing investment in fossil fuels does not support the widely held goal of limiting global warming to 2°C above pre-industrial levels, says a new report by University of Victoria and University of British Columbia researchers affiliated with the Corporate Mapping Project, a six-year research and public engagement initiative.

The Northwestern Pacific Ocean has been churning out tropical cyclones over the past couple of weeks and the tenth tropical depression formed as NASA's Aqua satellite passed overhead in space. Tropical Storm Warnings are in effect for Guam as 10W approaches the island.

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.
