Five Scary Effects due to Climate Change that May Happen in Your Lifetime

In the SciShow, you could watch this intently-made video, from its dramatic presentation, some of the worst case scenarios are deliberately illustrated if global climate is going to continuously change without a coordinated attempt for prevention of those inevitable problems that we have to deal with. The five well- known effects […]

New research in the journal Nature found that for each degree that the Earth's temperature rises, the amount of methane entering the atmosphere from microorganisms dwelling in freshwater wetlands -- a primary source of the gas -- will increase several times. The researchers analyzed nearly 1,600 measurements of temperature and methane emissions from 127 freshwater ecosystems across the globe (above), including lakes, swamps, marshes and rice paddies. The size of each point corresponds with the average rate of methane emissions in milligrams per square meter, per day, during the course of the study. The smallest points indicate less than one milligram per square meter, while the largest-sized point represents more than three milligrams. Credit: Image courtesy of Cristian Gudasz.

Emissions of Methane, a More Potent Greenhouse Gas Than CO2, Will Leap as Earth Warms

As carbon dioxide is generally regarded as the main cause of greenhouse gases, you may not know that methane could be nearly 30 times more powerful as a heat-trapping gas. The latest research result released by the journal Nature shows that with the rising temperature of Earth by each degree, the amount […]

Global Warming Led to Shrinkage of Early Mammals—Twice

Global Warming Led to Shrinkage of Early Mammals—Twice

About 55 million years ago, the Earth went through a series of global warming events—within 20,000 years, global temperature raised up for 6°C. During this period, the early horses called Hyracotherium, experienced a body-size decrease of about 30%. Scientists believe that the shrinkage in body size results in an increase […]

Global Warming and Arctic Sea Ice Melting

Global Warming and Arctic Sea Ice Melting

In recent years, when we are complaining about the hotter and hotter summer, the arctic sea ice content has reached the lowest point for the last 1,500 years by the end of 2012. Eric Post, professor in Department of Biology, and his co-workers from University of Pennsylvania have published an […]
