Duke University: Climate Change May Speed Up Forests’ Life Cycles
Instead of migrating northward via seed dispersal to cooler climates as predicted, trees in most forests are responding to a warming climate by staying in place – but speeding up their life cycles.

European Geosciences Union: Tiny plankton could have big impact on climate
As the climate changes and oceans’ acidity increases, tiny plankton seem set to succeed. While the smallest plankton groups would thrive under elevated carbon dioxide (CO2) levels, that could cause an imbalance in the food web as well as decrease ocean CO2 uptake, an important regulator of global climate.

University of Maryland: Scientists find “fingers” of heat below Earth’s surface
Scientists have used seismic waves to detect previously unknown “fingers” of heat, some thousands of miles long, in Earth’s upper mantle. This helps explain the “hotspot volcanoes” that give birth to island chains such as Hawaii and Tahiti.

Dept. of Energy/Pacific Northwest National Laboratory: Climate benefit for cutting soot, methane smaller than previous estimates
Cutting the amount of short-lived, climate-warming emissions such as soot and methane in our skies won’t limit global warming as much as previous studies have suggested, a new analysis shows.

Scientific American: Crop Pests Spreading North with Global Warming
Crop pests and diseases are moving towards the poles at about the same speed as warmer temperatures. New findings suggest that climate change is driving their relocation, and raises major concerns about food security.
