A global coalition of scientists led by William J. Ripple and Christopher Wolf of Oregon State University says “untold human suffering” is unavoidable without deep and lasting shifts in human activities that contribute to greenhouse gas emissions and other factors related to climate change.

The planet baked under the sun this summer as temperatures reached the hottest ever recorded and heat waves spread across the globe. While the climate continues to warm, scientists expect the frequency and intensity of heat waves to increase. However, a commonly overlooked aspect is the spatial size of heat waves, despite its important implications.

In the wake of recent wildfires that have ravaged northern and central California, a new study finds that the severity of fire activity in the Sierra Nevada region has been sensitive to changes in climate over the past 1,400 years. The findings suggest that future climate change is likely to drive increased fire activity in the Sierras.

Rising ocean temperatures have long been linked to negative impacts for marine life, but a Florida State University team has found that the long-term outlook for many marine species is much more complex -- and possibly bleaker -- than scientists previously believed.

Oregon has a new roadmap for addressing rising ocean acidification and hypoxia – two climate change-induced conditions that could have widespread consequences for the state’s ocean ecosystem and the economy.
