Number of flash floods and forest fires could increase with temperature, says TAU researcher Researchers are working to identify exactly how a changing climate will impact specific elements of weather, such as clouds, rainfall, and lightning. A Tel Aviv University researcher has predicted that for every one degree Celsius of warming, there will be approximately a 10 percent increase in lightning activity. This could have negative consequences in the form of flash floods, wild fires, or...
Major businesses call for preparation in the face of increasingly severe weather events and temperature rise WASHINGTON, July 10, 2012 /PRNewswire-USNewswire/ -- The following is being released by Partnership for Resilience and Environmental Preparedness (PREP): For the first time, leading companies from the food and beverage, insurance, investment, technology, and energy industries today released a step-by-step tool, Business ADAPT, for businesses to assess and prepare for the...
Temperatures are rising four times faster in the Artic than the global average, a new University of Melbourne study shows. The combination of melting sea ice and global warming are contributing to the different rates. Professor Ian Simmonds from the University of Melbourne’s School of Earth Sciences, co-author of the study, said this information showed that a combined effect at ground and atmospheric level played a key role in raising the rate of warming in the Arctic. “Loss of sea...
CHICAGO, July 9, 2012 /PRNewswire/ -- Today more than 150 community members of the Southeast Side of Chicago gathered in support of the Chicago Clean Energy project, a $3 billion private investment in the city. Frustrated by misinformation and rumor being circulated against the project, the group took a stand to set the record straight and to urge Governor Quinn to sign SB 3766, legislation that advances the project. Chicago Clean Energy will use gasification - a proven technology...
The calculations prepared by Mainz scientists will also influence the way current climate change is perceived An international team that includes scientists from Johannes Gutenberg University Mainz (JGU) has published a reconstruction of the climate in northern Europe over the last 2,000 years based on the information provided by tree-rings. Professor Dr. Jan Esper's group at the Institute of Geography at JGU used tree-ring density measurements from sub-fossil pine trees originating from...
Lawrence LeBlond for redOrbit.com - Your Universe Online An international team of researchers have found that even small volcanic eruptions can lead to a cooler climate if they coincide with weather systems such as monsoons, which boost aerosols produced by eruptions high into the atmosphere affecting global temperatures. The research, led by scientists from the University of Saskatchewan in Canada, suggests that the previously held belief that only massively energetic eruptions could...
A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures. The research appears in the July 6 issue of the journal Science. Adam Bourassa, from the U of S Institute of Space and Atmospheric Studies, led the research. He explains that until now it was thought that a massively energetic eruption was...
A study carried out by VTT Technical Research Centre of Finland indicates that extreme weather conditions cost EU transport system at least €15 billion a year. Currently, the greatest costs incurred are from road accidents, with the associated material damage and psychological suffering. However, costs arising from accidents are expected to decrease in volume, though time-related costs attributable to delays are projected to increase. In part, this is due to climate change, whose impact on...
The Sustainable Consumption Institute research claims food which families now take for granted, such as meat and fresh vegetables, could become too expensive for many if global temperatures rise in line with the current trends and reach 4°C within the lifetime of many people. Even if families continue to take steps to lower their carbon emissions from energy use, global farming emissions will continue to rise because of our growing appetite for energy-intensive foods and a rising demand...
A climate model accounting for the carbon dioxide (CO2) released into our atmosphere before the industrial revolution has been used to show the detrimental effect of carbon emissions on global temperature in the long-term. In a study published today, 4 July, in IOP Publishing's journal Environmental Research Letters, researchers from the Carnegie Institution for Science have shown that pre-industrial emissions from land use changes are responsible for about nine per cent of the increase 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...
