As Oceans Warm, Fish Are Finding New ZIP Codes

The study, published Wednesday in the journal Nature, employs a novel index that creates a fish thermometer of sorts, teasing out evidence of population shifts from fishery catch records during the past four decades. The study is the first to detect climate change-related shifts in the range of fish species on a global scale. In doing so, it provid… Read More

Carbon Dioxide Passes 400 PPM Milestone, NOAA Finds

Climate scientists recognize this 400 ppm mark as a symbolic milestone, illustrating the rapid increase of human-caused CO2 emissions over the past century. Numerous other climate data, gleaned from ice cores, ocean sediment, and other sources show that this is the highest CO2 concentration in the air in all of modern human history, possibly as far… Read More
