El Nino drives Panama butterfly migrationsOctober 6th, 2009 WASHINGTON - A long-term study has shown that El Nino, a global climate pattern, drives Sulfur butterfly migrations across the Panama Canal. Climate change has been linked to changes in the migration of butterflies in North America and Europe but this is one of the first long-term studies of environmental factors driving long-distance migration of tropical butterflies.
Global warming may cause "supertyphoons" to strike JapanSeptember 26th, 2009 WASHINGTON - Scientists have warned that increasingly powerful "supertyphoons" will strike Japan if global warming continues to affect weather patterns in the western Pacific Ocean. According to a report in National Geographic News, supercomputer simulations show there will be more typhoons with winds of 179 miles (288 kilometers) per hour-considered an F3 on the five-level Fujita Scale-by 2074.
1918 El Nino linked to severe flu pandemic in IndiaSeptember 15th, 2009 WASHINGTON - A new research conducted at Texas A and M University, US, has shown evidence of a possible link between El Nino and a severe flu pandemic in 1918 that adversely affected India. The findings are based on analysis of the 1918 El Nino, which the new research shows to be one of the strongest of the 20th century.
Researchers say weak El Nino under way, forecast strengthening in fall and winterSeptember 10th, 2009 Mild El Nino continues, strengthening expectedWASHINGTON — A weak El Nino is under way and it is expected to strengthen and last through winter, government climate researchers said Thursday. The periodic climate phenomenon is marked by warming of the central Pacific Ocean and changes in wind direction and air pressure that can affect weather around the world.

Summer seas grow steamy as oceans smash heat recordsAugust 20th, 2009 In hot water: World sets ocean temperature recordWASHINGTON — Steve Kramer spent an hour and a half swimming in the ocean Sunday — in Maine. The water temperature was 72 degrees — more like Ocean City, Md., this time of year.
From Maine to the Mediterranean, summer seas seem on boil as global oceans smash heat recordsAugust 20th, 2009 In hot water: World's ocean temps warmest recordedWASHINGTON — The world's oceans this summer are the warmest on record. The National Climatic Data Center, the government agency that keeps weather records, says the average global ocean temperature in July was 62.6 degrees.
New El Nino may lead to increased drought in IndiaAugust 3rd, 2009 LONDON - Meteorologists have warned that a new El Nino has begun, which may lead to increased drought in Africa, India and Australia, and may make 2010 one of the hottest years on record. El Nino is a periodic warming of the normally cold waters of the eastern tropical Pacific, the ocean region westwards out from South America along the line of the equator.
El Nino returns; severe impact on global weather expectedJuly 9th, 2009 WASHINGTON — El Nino's back. Government scientists say the periodic warming of water in the tropical Pacific Ocean that can affect weather around the world has returned.
New form of El Nino may increase chances of hurricanes making landfallJuly 3rd, 2009 WASHINGTON - A study by climatologists at the Georgia Institute of Technology suggests that a new form of El Nino may be changing potentially causing not only a greater number of hurricanes than in average years, but also a greater chance of hurricanes making landfall. "Normally, El Nino results in diminished hurricanes in the Atlantic, but this new type is resulting in a greater number of hurricanes with greater frequency and more potential to make landfall," said Peter Webster, professor at Georgia Tech's School of Earth and Atmospheric Sciences.
Study says El Nino comes in two types, one encouraging more hurricanes, one with fewerJuly 2nd, 2009 New form of El Nino may increase Atlantic stormsWASHINGTON — El Nino may have a split personality. The warming of the tropical Pacific Ocean has long been known to affect weather around the world, but researchers now say it may come in two forms with different impacts.
Scientists find direct relationship between CO2 emissions and global warmingJune 11th, 2009 WASHINGTON - In a new study, a team of scientists has found a direct relationship between carbon dioxide (CO2) emissions and global warming. The study was done by Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment, along with colleagues from Victoria and the UK.
El Nino climate condition could develop this summer, forecasters sayJune 8th, 2009 Forecasters say El Nino may be developingWASHINGTON — A new El Nino could be approaching. Sea-surface temperatures have been warming in the tropical Pacific Ocean, suggesting the potential for the development of the El Nino climate phenomenon this summer, according to the National Oceanic and Atmospheric Administration.
Ashley Judd, TV host Jeff Corwin call on Congress to help wildlife survive global warmingApril 23rd, 2009 Ashley Judd urges Congress to fight global warmingWASHINGTON — Actress Ashley Judd and TV personality Jeff Corwin are urging Congress to spend $7 billion a year to help safeguard America's wildlife from the impact of global warming. Judd is a longtime environmental activist.
Reduction in airborne dust responsible for recent warming trend in Atlantic OceanMarch 27th, 2009 WASHINGTON - A new study has determined that the recent warming trend in the Atlantic Ocean is largely due to reductions in airborne dust and volcanic emissions during the past 30 years. Since 1980, the tropical North Atlantic has been warming by an average of a quarter-degree Celsius (a half-degree Fahrenheit) per decade.
2008 was Earth's ninth warmest year since 1880, says NASAFebruary 24th, 2009 WASHINGTON - Climatologists at the NASA Goddard Institute for Space Studies (GISS) in New York City have found that 2008 was the coolest year since 2000, and also the ninth warmest year since 1880. The GISS analysis found that the global average surface air temperature was 0.44C (0.79F) above the global mean between 1951 and 1980, the baseline period for the study.
