A new study links the ban of CFC gases mandated by the Montreal Protocol of 1987 to a slowdown in temperature increases since the mid 1990s.
The Environmental Protection Agency today is hosting a “Public Listening Session” at the Metcalfe Federal Building in Chicago, allowing the public to weigh in on the Obama administration’s
While we learned earlier this year that 2012 was the ninth warmest year since 1880, this week we were greeted with news that greenhouse gases, like carbon dioxide, methane and nitrous oxide, hit record highs in that same year.
In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires.
Yet the instrument of pricing global CO2 emissions could generate a revenue of 32 trillion US dollars over the 21st century, exceeding by far the 12 trillion US dollars reduction of fossil fuel owners' profits.
Wind and solar energy alone will not be enough to prevent severe global warming – in order to adequately reduce fossil fuel emissions, clean nuclear power plants will be required, some of the planet’s top climate scientists wrote in an open letter sent to leading environmental organizations on Sunday.
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.
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...
Growing Degree Days are another huge part of our lives even though we may not deal with them directly. Growing degree days have to deal with the growing of fruits and vegetables along with other various crops that are grown throughout the United States for our personal use. As we examine the Baltimore Maryland area we can see how the impacts of a normal, El-Nino and La-Nina cycle have an impact on just the one month of March. These numbers are based on 50F which is the base number used for...
If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...
The above graph highlights how the ENSO has an impact on water temps. Northern Gulf of Mexico during EL-Nino: The first part of March during this EL-Nino cycle saw water temps in the 56-60F range, while the 8-14th saw water temps warm to the 60-64F range. By the third week of March temps had maintained 60-64F. The last week of March the temps dropped back to around 56-60F. Northern Gulf of Mexico during LA-Nina: The first week of March saw water temps approach the 70-72F range, by the...
Honolulu is located in the Pacific Ocean and has a mostly marine time climate. Honolulu has a pretty consistent temperature average from month to month. This is a look at the La-Nina impacts on the local area. January 2010: For the month of January it is typical to see average high temps in the 80’s while overnight lows drop into the 70’s. During the El-Nino event January temps were 60% of the month at the normal, while 40% of the month was marked with above temps and 0% of the month...
