Troubled Waters On the Horizon For Our Oceans
Stare out upon the ocean at sunset and you can almost convince yourself that all is well beneath the surface. Sadly, the exact opposite is very true. Three new studies reveal just how sick the oceans are, as well as just how big a role humans are playing. Let’s begin with climate change: according to a report from NASA and […]
Read morePredators key to helping prey evolve with climate change
The key to helping animals evolve quickly in response to climate change could actually be their predators, according to a new UBC study. The study is one of the first to show that species interactions, meaning the way species interact with each other in an ecosystem, like in a predator-prey relationship, is important to understanding how animals will respond to […]
Read moreWhy the oceans are in trouble
Why the oceans are in trouble! The oceans can no longer handle the damage brought on by the 7 billion people on Earth. Over the decades, the human race has over-fished specific species to near extinction, and polluted them with carbon dioxide emissions, toxic chemicals, garbage, and unrecycled plastics. A shocking new study, recently published in Science, warned […]
Read moreMore certainty on global warming
An influential panel of climate scientists has expressed higher confidence than ever that human activity is the main cause of the rise in global temperatures since the 1950s, Reuters.com reports. A leaked draft of an upcoming report of the United Nations’ Intergovernmental Panel on Climate Change, based on a broad analysis of published scientific studies, concludes with 95 percent certainty […]

A research paper published in Nature Climate Change predicts widespread death of needleleaf evergreen trees (NET) within the Southwest United States by the year 2100 under projected global warming scenarios. The research team that conducted the study, which includes University of Delaware’s Sara Rauscher, considered both field results and a range of validated regional predictions and global simulation models of […]

Between fighting wildfires and rerouting the Iditarod, Alaska has had a tough time with climate change. But at least there’s one good outcome: local food. In Bethel, a town in southwestern Alaska, farmer Tim Meyers is taking advantage of rising temperatures to grow food in the previously inhospitable tundra. NPR reports: At the 15-acre organic farm, which has been operating for more […]
Read moreWater Flow returned to Mexican Part of Colorado River
2013 – Colorado River Delta, Mexico: Water began flowing in the Mexican part of the Colorado River for the first time in decades. Dams, including the Hoover Dam and the Morelos Dam, usually keep most of the river’s water in the U.S. and divert some to Tijuana and surrounding farmland. The joint U.S.- Mexican International Boundary and Water Commission authorized […]
Read moreHow Native American depopulation impacted ecology
There is little dispute that in the wake of European colonists’ arrival in the New World, Native American populations were decimated by disease and conflict. But when it comes to the timing, magnitude, and effects of this Native American depopulation — it depends on who you ask. Many scholars claim that disease struck the native population shortly after their first […]
Read moreA warmer world will be a hazier one
Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]
