Prospects have been fading for an El Niño event in 2014, but now there's a glimmer of hope for a very modest comeback.
While US President Barack Obama and Hollywood star Leonardo DiCaprio attracted much of the press coverage for the 2014 UN Climate Change Summit on Tuesday, behind the scenes more than 120 world leaders met together to debate policy and commit resources to solving the growing issue.
By the end of the year, NASA plans to have a network of 15 monitoring stations around the Los Angeles basin that will use commercially available high-precision greenhouse gas analyzers to continually sample the local air as part of its Megacities Carbon Project.

GREENBELT, Md., Sept. 22, 2014 /PRNewswire-USNewswire/ -- Accredited news media are invited to NASA's Goddard Space Flight Center in Greenbelt, Maryland, on Friday, Oct.
Carbon dioxide emissions, which are the one of the main contributors to global warming, are expected to reach a record high of 40 billion tons in 2014, according to new Global Carbon Project (GCP) data released this weekend.
The fall foliage transformations that so colorfully mark the start of the autumn season could soon start arriving later and lasting longer due to climate change, researchers from Princeton University report in the latest edition of the journal Global Ecology and Biogeography.

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...
Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...
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...
Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...
Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...
