Latest Global warming Stories
While scientists have known for several years that some mammals became smaller during a period of warming known as the Paleocene-Eocene Thermal Maximum, researchers have found a second instance of mammalian “dwarfing” attributable to increasing temperatures.
The apparent stabilization of atmospheric temperatures over the past decade -- often cited by climate change skeptics as evidence that global warming has slowed down or stopped -- is actually caused by a radical increase in the amount of heat being absorbed by the oceans, according to a new study.
A new study shows that although a significant build-up in greenhouse gases in the atmosphere would alter worldwide precipitation patterns, a widely discussed technological approach to reduce future global warming would also interfere with rainfall and snowfall.
A new Friends of Science study by research director Ken Gregory shows that the Canadian climate model CanESM2, used by the Intergovernmental Panel on Climate Change (IPCC) to predict global warming,
Although a significant build-up in greenhouse gases in the atmosphere would alter worldwide precipitation patterns, geoengineering would also interfere with rainfall and snowfall.
Gordon Hunter’s new book addresses global warming, climate change. Nashville (PRWEB) October 26, 2013 NASA’s climate home page,
Collective risks are hard for people to grasp. A good example of this is climate change. Despite annual climate summits, no specific measures have arisen because people place greater value on immediate material rewards than on investing in future quality of life.
New research suggests that the southern part of the Amazon rainforest faces a higher risk of dieback as a result of seasonal drying than reported by climate models used by the most recent Intergovernmental Panel on Climate Change (IPCC).
A panel of 50 scientists from 15 countries says the newest report on climate change from the United Nations is filled with concessions that its past predictions were too extreme and contains “at
Speaking from the annual meeting of the International Development Finance Club, Ban Ki-Moon called on the entire international community to commit to providing increased financial investment to help combat the deleterious effects of climate change.
An urban heat island (UHI) is a metropolitan area that is drastically warmer than its surrounding rural areas because of human activities. The phenomenon was first looked into and described by Luke Howard during the 1810s, although he wasn’t the one to name the phenomenon. The difference in temperature is normally bigger at night as opposed to during the day, and it most obvious when winds are weak. Seasonally, UHI is seen during the summer and the winter. The key cause of the urban heat...
Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...
Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...
The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...
- Having no light.
- Of or relating to the region of a body of water that is not reached by sunlight and in which photosynthesis is unable to occur.
