In fact, new NASA-led research indicates that tropical forests are absorbing an estimated 1.4 billion metric tons of the global 2.5 billion metric tons of CO2 being absorbed worldwide.
Over the weekend, climate negotiators from nearly 200 nations approved the “Lima Accord,” an agreement to reduce greenhouse gas emissions by cutting back on the burning of coal, natural gas,
In response to the Friends of Science climate change billboard campaign, the Sierra Club Canada Foundation published a blog piece on December 4, 2014, making claims about the Friends of Science
Best known as ‘laughing gas,’ the greenhouse gas nitrous oxide is often forgotten in the conversations surrounding global warming.
Ocean temperatures around the world are increasing and one consequence of those rising temperatures is the release of methane from the sea floor off the coast of Washington.
A new study is shedding new light on a sudden intense increase in rainfall that occurred in parts of Africa around 15,000 years ago.
The world is getting warmer. It comes as no surprise, therefore, when researchers announce as they did this past September that Arctic sea ice extent is still below normal.
November 2014 broke cold and snow records across North America, but according to a new BBC report, 2014 is still globally the warmest it has ever been.
New research, led by the National Center for Atmospheric Research, demonstrates for the first time that an increase in greenhouse gas concentrations thousands of years ago was a key factor in

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...
