Warming climate making fine particulate matter from wildfires more deadly and expensive

CORVALLIS, Ore. – Scientists say human-caused climate change led to 15,000 additional deaths from wildfire air pollution in the continental United States during the 15-year period ending in 2020.

About 35% of the additional deaths attributed to climate change occurred in 2020, the year of the historic Labor Day fires in the Pacific Northwest as well as major blazes in California, Colorado and Arizona.

Researchers find new species of electricity-conducting organism, name it after Tribe

CORVALLIS, Ore. – Scientists have identified a novel species of bacteria that acts as electrical wiring, potentially ushering in a new era of bioelectronic devices for use in medicine, industry, food safety, and environmental monitoring and cleanup.

The researchers who discovered the new cable bacteria species in a mud flat at the Oregon coast named it Ca. Electrothrix yaqonensis in honor of the Native Americans of the region where the species was found.

New Oregon climate assessment documents continued warming and signs of adaptation

CORVALLIS, Ore. – Oregon is becoming warmer and more prone to drought and will see less snow due to climate change, but people and businesses are also adapting to the challenges of a warming planet, the latest Oregon Climate Assessment indicates.

The assessment, released today by the Oregon Climate Change Research Institute at Oregon State University, shows that Oregon’s annual average temperature increased by 2.2 degrees Fahrenheit over the last century and is likely to become as much as 5 degrees Fahrenheit warmer by 2074.

Increased wildfire activity may be a feature of past periods of abrupt climate change, study finds

CORVALLIS, Ore. – A new study investigating ancient methane trapped in Antarctic ice suggests that global increases in wildfire activity likely occurred during periods of abrupt climate change throughout the last Ice Age.

The study, just published in the journal Nature, reveals increased wildfire activity as a potential feature of these periods of abrupt climate change, which also saw significant shifts in tropical rainfall patterns and temperature fluctuations around the world.

New ice core data provides insight into climate ‘tipping points’ during the last Ice Age

CORVALLIS, Ore. – A changing climate triggers a sudden shift in ocean circulation, creating weather havoc and plunging Earth into an abrupt new Ice Age.

It sounds like the basis for a Hollywood blockbuster - the 2004 science fiction disaster film “The Day After Tomorrow,” has similar plot lines – but it’s actually a scenario that played out multiple times during the last Ice Age, which ended more than 11,000 years ago.
