Exploratory missions to Mars, such as NASA’s Curiosity Rover, have provided more and more evidence that Mars at one time was warm enough for water to flow on its surface. Now a new study published in the journal “Nature Geoscience” has found that those ancient, warm periods on the Red Planet probably took place in […]

A new report by the Global Carbon Project, an international science/environmental group, shows that the emission of carbon dioxide, one of the world’s top greenhouse gases – which scientists say leads to global warming – will not only rise once again in 2014, but will set a record high of 40 billion metric tons. As […]

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 […]

An international team of climate researchers says the world’s climate has warmed at an unparalleled rate over the past century, but has also found that this warming hasn’t occurred everywhere at the same rate. Their research also indicates that some parts of the world actually cooled during the 100-year time period. The new study, published […]

Scientist 99% Sure Global Climate Change is Man-Made

A Canadian physicist says his studies have all but completely ruled out the premise that global warming throughout the industrial era has not been merely a natural fluctuation in Earth’s climate, as some have been claiming.  The assertion was made after the scientist analyzed temperature data from as far back as 1500. “This study will […]

Report Provides Further Evidence People Cause Climate Change

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 […]

Study Finds Energy Use in Cities Causes Winter Warming
