Oceanic Phytoplankton contribute to ice formation in clouds

<!– –> Researchers from the Arctic Research Programme, managed at British Antarctic Survey, have shown for the first time that phytoplankton (plant life) in remote ocean regions can contribute to rare airborne particles that trigger ice formation in clouds. Results p

Huge Permafrost study will help improve climate models

<!– –> This Saturday at a conference in Quebec, Canada an international research team will present the first online data portal on global permafrost. In the Global Terrestrial Network for Permafrost researchers first collect all the existing permafrost temperature an

Plants migrate to higher altitudes because of climate change

Although most of the world’s species diversity is found in tropical areas, there are very few studies that have examined whether tropical mountain species are affected by climate change to the same extent as temperate species. A new study has now determined that major changes have tak

New study finds massive eruptions likely triggered mass extinction

Around 252 million years ago, life on Earth collapsed in spectacular and unprecedented fashion, as more than 96 percent of marine species and 70 percent of land species disappeared in a geological instant. The so-called end-Permian mass extinction ­— or more commonly, the “Great Dying

MIT study shows climate change mitigation potential of geoengineering the oceans

Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species a

The long-term effects of the Exxon Valdez oil spill

<!– –> For 25 years, methodical research by scientists has investigated the effects of the Exxon Valdez oil spill in 1989 on Alaskan communities and ecosystems. A new study released today into the effects of the 1989 Exxon Valdez oil spill in Alaska shows that embryo

Ice sheets may be more resilient than previously thought

Sea level rise poses one of the biggest threats to human systems in a globally warming world, potentially causing trillions of dollars’ worth of damages to flooded cities around the world. As surface temperatures rise, ice sheets are melting at record rates and sea levels are ri
