The amount of CO2 is increasing all the time – we just passed a landmark 400 parts per million concentration of atmospheric CO2, up from around 280ppm before the industrial revolution. That’s a 42.8% increase. A tiny amount of CO2 and other greenhouse gases, like methane and water vapor, keep the Earth’s surface 30°Celsius (54°F) warmer than it would be […]

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 […]

One of the most common arguments of those skeptical of global warming is that the Medieval Warm Period (800-1400 AD) was as warm as or warmer than today. Using this as proof to say that we cannot be the cause of current global warming is a faulty notion based upon rhetoric rather than science. So what are the holes in […]

Before the Flood, directed by Fisher Stevens, is a documentary that captures a three year personal journey of the Academy Award-winning actor and U.N. Messenger of Peace Leonardo DiCaprio. What was Leonardo Dicaprio’s Mission in Before the Flood? His mission was to explore the level of destruction climate change has caused around the world, and to sensitise the world’s nations […]

Climate change may have helped to alter the course of history. A period of extreme and unprecedented cooling in the northern hemisphere 1,500 years ago may have reduced the eastern Roman empire, set the stage for a famine and a devastating pandemic that killed millions, and favored the rise of the Islamic forces that created the Arab empire. The so-called Little […]

The newest professor in the University of Rhode Island’s College of the Environment and Life Sciences, Hollie Putnam, thinks some corals and shellfish might have good enough “memories” to buffer the changes in ocean chemistry that are resulting from the effects of climate change on coral reefs. A native of Minnesota who earned a doctorate at the University of Hawaii, […]

Climatologists have started to drill into the oldest ice core in Antarctica to find some air that may have been there around 1 million to 900,000 years ago. The teams are from Australia, China, and Europe in a friendly type competition to find samples of air that is about 1.5 million years old. They would like to find out what […]

Climate change is killing off Bees In India. A lethal combination of climate change and human interference is helping to wipe out colonies of the giant honeybees on which many plants and trees in India depend for their survival. The precise cause of colony collapse disorder (CCD) is not known, but researchers say that the loss of the bees will […]

There is some million year old ice deep in Antarctica that researchers are hoping to find out information on the earths past. They believe that they can predict the effect of co2 in some bubbles that are in the ice. Climate change is on their minds by unearthing these bubbles. Scientists from the Australian Antarctic Division are getting so close […]

In forests worldwide, drought consistently has had a more detrimental impact on the growth and survival of larger trees, new research shows. In addition, while the death of small trees may affect the dominance of trees in a landscape, the death of large trees has a far worse impact on the ecosystem and climate’s health, especially due to the important […]
