By Luisa Cristini, PhD, University of Hawaii at Manoa. [Note from the editor: This is the fourteenth in a series of blog entries that will focus on introductory topics in climate dynamics and modeling, and will serve to provide insight into the current understanding of the science.] Changes in external forcing (e.g., solar forcings, astronomical […]
Forecasting Extreme Weather
Climate and Famine: Two Examples
June 4, 2012
By Jason Klein, IEDRO’s Environmental Writer and Editor We have all witnessed the effects of famine – malnourished children, dead herds of cattle, the plaintive appeals of Sally Struthers. But what if a famine could be predicted, and then we could work to prevent it? The good news is that by delving into past instances […]
Capacity Building Workshop on Data Rescue and Climate Change Indices: A Contribution to the Implementation of the Global Framework for Climate Services in the Caribbean
May 23, 2012
By Teddy Allen, IEDRO Science Applications Manager May 7-10, 2012 –The University of the West Indies, Mona, Kingston, Jamaica. IEDRO recently participated in the Capacity Building Workshop on Data Rescue and Climate Change Indices as part of the Expert Team on Climate Change Detection and Indices (ETCCDI). The remaining ETCCDI members supporting the workshop represented NOAA, […]
Tree Rings: A Type of Weather Data
May 8, 2012
By Penny Paugh Trees grow on every continent except Antarctica, and the rings they contain embody a record of climate change going back thousands of years. Each ring represents a single year’s growth, so not only can a ring count tell us how old a tree is, but they can also help reconstruct climatic history […]
The Economic Impact of Extreme Weather in the US
May 4, 2012
A team of social scientists and economists from Colorado and California recently completed a study on the United States economy’s sensitivity to weather variability: extreme heat, extreme cold, droughts, and floods. This study marked the first time that US economic susceptibility to extreme weather had been explicitly quantified. Seventy years of atmospheric data were used […]
The UK Cuts Antarctic Research
May 2, 2012
By Penny Paugh The British polar research community is at risk. The UK government plans massive cuts, more than 25 percent, to the budget of the British Antarctic Survey (BAS). The cuts are ordered as a means to reduce the UK’s national deficit. BAS is the leading UK polar research body and one of the […]
Galápagos: A Living Ecological Lab
April 27, 2012
By Penny Paugh The Galápagos Islands off the western coast of South America are renowned as an evolutionary and ecological living laboratory. These Pacific islands can serve as a barometer to gauge how climate and ecosystems interact, and provide a unique window into the relationship between mankind’s rapid development and a continuously changing environment. The […]
Rwandan Drought; Ongoing Climate Concerns
April 25, 2012
by Aura Lawson La Niña has persisted longer than expected this year, and with it comes agricultural uncertainty for many countries across the globe. Rwanda is no exception. Anthony Twahirwa, head of Rwanda’s Meteorological Center, explains that their forecasting agency expected decreased rainfall as a result of La Niña, or abnormally cool waters in the […]
Recent Solar Storm Floods Earth’s Upper Atmosphere
April 17, 2012
By Pennell Paugh Though the Earth is constantly bombarded by charged particles from the Sun, which emits material in all directions in a process known as the solar wind, sometimes the Sun ramps up magnetic activity on its surface, triggering huge flares of insidious plasma. NASA Science News announced that a huge solar storm occurred […]
Isolating Climate Change Constraints
April 3, 2012
By Penny Paugh There are many factors that affect the global temperature of the planet, including the rise and fall of greenhouse gases, solar activity, light-scattering atmospheric pollutants, heat transfer among the land, sea, and air, and the presence or absence of forests to process carbon dioxide. Researchers at the University of Oxford tweaked three […]
