New climate modeling research shows that an increase in greenhouse gas emissions has a direct link to a changing climate, Nature reports. In two studies released by British scientists, computer climate simulation found that the biggest differential in rising precipitation is not natural variability in the atmosphere but rather greenhouse gases released by humans. In particular, this suggests links betweenRead More …

Increased carbon dioxide levels can affect some plants’ defense mechanisms against preying insects, a recent study from the University of Michigan has found. In an evaluation of chemical and physical changes of milkweed plants in response to elevated levels of carbon dioxide, some plant families increased their production of toxic compounds used to deter hungry insects. In plants whose toxin levelsRead More …
