When it comes to greenhouse gases that contribute most to global warming, most people think of substances such as carbon dioxide, methane or even hydrofluorocarbons. But did you know that, for a while now, scientists have considered the vapor of the most important ingredient in sustaining life on Earth – water – as one of […]

NASA Launches Mission to Study Atmospheric C02 NASA’s successfully launched its Orbiting Carbon Observatory-2 (OCO-2) from California’s Vandenberg Air Force Base Wednesday morning. OCO-2’s mission, which is expected to last at least two years, will study atmospheric carbon dioxide, which scientists say is not only an important element of Earth’s carbon-cycle, but also the primary […]

Scientist 99% Sure Global Climate Change is Man-Made

New evidence suggests climate change is human caused and that if the release of greenhouse gases continues unabated, changes to the world’s climate will greatly exceed those that have taken place so far. The new joint report from the US National Academy of Sciences and the Royal Society, the national science academy of the UK, […]

Global Precipitation Changes Linked to Human-induced Climate Change

A new study shows changes in precipitation are affected by human activities and can’t be explained by natural phenomena, such as El Niños and La Niñas. Scientists from the Lawrence Livermore National Laboratory in California published the study in the Proceedings of the National Academy of Sciences. The researchers suggest two mechanisms will probably cause […]

As global temperatures rise, so do our levels of hostility and violence, according to a new study. Scientists from the University of California, Berkeley and Princeton University  discovered a strong link between shifts in climate to human violence around the world.  The study found that even minor climate deviations, such as slight changes in normal […]

Study Finds Energy Use in Cities Causes Winter Warming
