Increasing aridity could lead to major problems for societies and ecosystems in already-arid places Warming climate may mean less rainfall for drought-sensitive regions of the Southern Hemisphere, according to results just published by an international research team. Geoscientist Curt Stager of Paul Smith's College in Paul Smiths, N.Y., and colleagues found that rainfall in South Africa during the last 1,400 years was affected by temperature--with more rain falling during cool periods...
UC Riverside-led team identifies black carbon and tropospheric ozone as most likely drivers of large-scale atmospheric circulation change in the Northern hemisphere tropics Black carbon aerosols and tropospheric ozone, both manmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research by a team of scientists shows. While stratospheric ozone depletion has...
SAN FRANCISCO, May 17, 2012 /PRNewswire/ -- A new series of reports from University of California, Berkeley (UCB), University of California, Berkeley, School of Law, and Resources for the Future (RFF) experts examine how California might spend the funds generated by the state's soon-to-be-launched carbon market under AB 32 (The California Global Warming Solutions Act). The four studies, commissioned by the nonpartisan nonprofit organization Next 10, together provide legal and...
Scientists in Australia have used 27 natural climate records to create the first large-scale temperature reconstruction for the region over the last 1000 years. This is the first study of its kind. Researchers at the University of Melbourne led the study. They used a range of natural indicators including tree rings, corals and ice cores to study the temperatures in Australia over the past millennium and compared them to climate model simulations. "The results show that there are no...
Fighting over patents may seem silly when phone or computer manufacturers are involved. After all, no normal person knows how computers connect to a network or how photos are shared over the internet. However, normal people can and do feel the effects of global warming, like the rash of weird weather we’ve had in the past few years. Therefore, it’s a bit frustrating and surprising that something as seemingly insignificant as patents have curbed a UK climate experiment to try and slow...
Measurement, reporting, and verification of greenhouse gas emissions in studied nations is well-established, but estimating the effect of climate policies is more difficult SAN FRANCISCO, May 16, 2012 /PRNewswire-USNewswire/ -- Climate Policy Initiative (CPI)'s has completed an analysis of national systems that track emissions and activities to reduce emissions in the U.S., Germany, Italy, and China. The analysis revealed that existing systems allow these nations to determine if they...
For the first time, researchers have been able to combine different climate models using spatial statistics - to project future seasonal temperature changes in regions across North America. They performed advanced statistical analysis on two different North American regional climate models and were able to estimate projections of temperature changes for the years 2041 to 2070, as well as the certainty of those projections. The analysis, developed by statisticians at Ohio State...
WASHINGTON, May 15, 2012 /PRNewswire-USNewswire/ --The Annual Meeting & Scientific Convening of the Global Adaptation Institute (GAIN) centered on one theme - the urgent need to adapt to the changing global climate requires pragmatic solutions with the private sector leading the effort. GAIN Founding CEO Dr. Juan Jose Daboub, former Managing Director at the World Bank, noted that even five years ago, the topic of adaptation wasn't being discussed. Now, with the backing of...
University of Utah and Harvard scientists develop way to enforce future greenhouse gas treaty If the world's nations ever sign a treaty to limit emissions of climate-warming carbon dioxide gas, there may be a way to help verify compliance: a new method developed by scientists from the University of Utah and Harvard. Using measurements from only three carbon-dioxide (CO2) monitoring stations in the Salt Lake Valley, the method could reliably detect changes in CO2 emissions of 15 percent...
In the run-up to the G8 summit in Camp David, Maryland, the German National Academy of Sciences Leopoldina, in partnership with the national science academies of the G8 member states and seven other science academies, has equipped the world leaders with a set of recommendations on addressing some of the planet's most pressing challenges. The partners' three statements on the topics of water and energy, greenhouse gas reduction and ways of building resilience to natural and technological...

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...
