I read the news today, oh boy. Wind farms are causing global warming? No, but maybe a bit of local warming. A new study of wind turbines in Texas shows that rotating blades force warm air downwards at night, causing ground temperatures to rise by up to 0.72C (1.3F). And so the headlines read that wind farms warm the night, or as Reuters states ‘Wind Farms Might Have Warming Effect’. But they also cool ground temperatures during the day according to previous research. Isn’t this piece of information equally significant? The Guardian doesn’t include it in their article, while Discovery…

A new kind of immigrant is being spotted in British seas. Species of whales, dolphins and seals, which are customarily at home in more tropical waters, are making their way to the UK, perhaps due to rising sea temperatures. If climate change continues to warm British waters, as predicted by scientists, more aquatic mammals will follow their food sources from the warmer climes of Africa and the Pacific all the way to the UK. The widespread use of digital cameras is making it easier for scientists to confirm such sightings and collect more accurate data. Animals from the tropics, including…

A new study explores the relationship between tropical storms and the color of the ocean. Areas of ocean with more chlorophyll-rich phytoplankton have a green tint. Chlorophyll prevents sunlight from penetrating deep into the ocean meaning surface temperatures remain higher. Warmer surface temperatures mean more tropical storms, such as cyclones or hurricanes. From an AFP report: Cold water in turn causes changes in air circulation patterns, forcing strong winds aloft, “which tend to prevent thunderstorms from developing the necessary superstructure that allows them to grow into hurricanes,” the researchers said. Massive spiraling ocean currents called gyres are areas with less…

The massive 160 square mile (414 sq km) ice island that broke off from Greenland’s Petermann glacier earlier this month is ‘certainly a manifestation of warming’ according to Dr. Richard Bates of the University of St. Andrews, Scotland. Andrews, a geophysicist, is part of a British-led expedition in Greenland, which is measuring glaciers including the Petermann. From an article in the Telegraph: Dr Richard Bates, who is monitoring the ice alongside researchers from America, said the expedition had expected to find evidence of melting this year after “abnormally high” temperatures in the area. Climate change experts say that globally it…

Bites caused by Blanford flies – a regional species of black fly in the UK – are on the rise this summer, with human activity and hot weather taking the blame. One factor contributing to the rise in black fly bites in the Norwich area of England include the large amount of water features being built in British gardens, which facilitate the flies’ reproduction in suburban areas. From a report in the Telegraph: Experts blamed the recent warm and humid [weather] which has made insects, including horseflies, mosquitoes and midges, more active, particularly in the evening. People are also spending…

A new Met Office report, compiled of several recent studies, documents what scientists consider undeniable evidence of a changing climate and warming planet. 10 indicators of global warming were incorporated in the report, including rising land and sea-surface temperatures, ocean heat, sea levels and humidity; and a reduction in Arctic sea ice, glaciers and springtime snow cover in the Northern Hemisphere. From an article in the Wall Street Journal: The State of the Climate 2009 report, published Wednesday as a special supplement to the Bulletin of the American Meteorological Society, was compiled by 300 scientists from 48 countries and drew…

June 2010 has gone on record as the hottest June since temperatures have been documented, according to the US National Oceanic and Atmospheric Administration (NOAA). The scientific body’s National Climatic Data Center records go back to 1880 and also show the January-June and April-June periods to be the warmest ever recorded. Though temperatures were warmer than average throughout much of the globe, Peru, central and eastern US and both eastern and western Asia experienced the most markedly hotter temperatures. Southern China, Scandinavia and the northwestern US were actually cooler than average, as was Spain. From an AFP report: In June,…

In a piece of news that may sound bizarre to some, record-breaking temperatures in Russia are causing a rash of deaths by drowning. Over 1,200 have drowned recently, sometimes combining swimming with alcohol to seek relief from temperatures approaching 40C (104F). An official from Russia’s Emergencies Ministry attributed most of the drowning deaths to this dangerous mix. From a CNN report: Officials have urged citizens to take a siesta in the afternoon to avoid the hottest part of the day. Cases of heat stroke and sunburn have increased in children, and adults with heart problems and diabetes are suffering complications….

An analysis based on national emissions targets suggests that global temperatures will rise by 4C (7.2F) by 2100. Six months after over 100 governments pledged to limit their countries’ emissions in order to keep temperatures from rising more than 1.5-2C (2.7-3.6F) above pre-industrial levels a major international study of over 60 nations, called the Climate Scoreboard, has calculated that temperatures are set to double if current targets are held to. Another study by Climate Analytics, at the Potsdam Institute in Germany, suggests there is “virtually no chance” world governments will keep the temperature rise to below 2C, and the rise…

Today’s temperatures are predicted go as high hit 30C (85F) making it the hottest day of the year in England, with temperatures highest in London and the southeast. World cup fever – and the more civilized pursuit of eating strawberries and cream whilst watching a considerably smaller yellow ball move backwards and forwards at a much faster rate than a football ever could when North Korea are not playing – is gripping the country. But so is a heatwave. According to an article in the Guardian, ‘MeteoGroup weather forecaster Steve Ellison said the heatwave was caused by a ridge of…

Arctic temperatures have risen twice as fast in recent decades as temps in the rest of the world. Melting sea ice – considered part of a positive feedback loop – as well as wind, cloud and ocean current changes have been suspected of driving this rapid warming, known as Arctic amplification. A positive feedback loop is a system where the cause and effect perpetuate one another, like a vicious circle. A new study shows that Arctic warming from melting sea ice may be driving a positive feedback loop between rising temperatures and disappearing ice. From an article in the Guardian:…

Longer growing seasons and higher concentrations of CO2 may encourage faster growth rates in trees, according to a 22-year scientific study of mixed hardwoods in the eastern United States. During the study average temperatures increased by 0.3 degrees while the growing season was extended by 7.8 days. Furthermore, the CO2 concentration in the forest air went up 12%. Higher concentrations of carbon dioxide and extended growing seasons could be favourable for agriculture in some parts of the world, mainly in the northern hemisphere. The study in Maryland suggests that the extra growth in trees could help to act as a…

The unseasonably cold weather that has been plaguing parts of North America, Asia and Europe has no relationship to climate change and can be explained by Arctic oscillation, according to New York Times science reporter Kenneth Chang. Well that clears that up nicely, doesn’t it? No? Well, in an article from January 9th Chang explains the phenomenon of Arctic oscillation: ‘Opposing atmospheric pressure patterns at the top of the planet occasionally shift back and forth, affecting weather across much of the Northern Hemisphere.’ –New York Times The unusually cold temperatures being experienced by parts of the world in recent weeks…

It’s the environmental equivalent of someone posting dorky junior high school photos of you on facebook, except it’s not funny. Instead of braces, feathered hair and bad skin, this time carcinogens, chemical pesticides and industrial compounds are returning from the past to haunt us. Starting to feel nostalgic? Me neither. Glaciers melting in the Swiss Alps due to higher than normal temperatures are apparently releasing toxic chemicals that have been stored in ice for up to 50 years. Swiss researchers are finding evidence of dangerous buildups of banned chemicals like DDT, dioxins and other out-dated POPs – or Persistent Organic…
