How cold is Europe? Cold enough for the Danube River to freeze Just how extraordinary has this winter been in Europe? The Danube River has frozen, for one. Europeans have been shivering under a blanket of cold air that has sent temperatures plummeting and snows drifting. Across the continent, hundreds have died from exposure to the cold. The Danube's freezing is just one of many severe winter events in the continent this year. At least four Balkan nations suspended shipping on the Danube on Feb. 14 because of heavy ice on the river, according to news reports. Keeping Europe frozen is a climate pattern called a "Russian Winter." The Danube flows through 10 countries, so precise records of its last freezing are not easy to come by. "I looked back over 20 years and found a few significant cold snaps, but I didn't find anything quite as strong as this one," Andrews told OurAmazingPlanet. On Jan. 13, 2003, the weather in Belgrade dropped to a low of minus 11 degrees Fahrenheit (minus 24 degrees Celsius). "We're talking pretty darn cold here," Andrews said.
RealClimate by Eric Steig Along with various Seattle business and community leaders, city planners and politicians, a large group of scientists from the University of Washington got a chance to preview the new film, An Inconvenient Truth, last week. The film is about Al Gore’s efforts to educate the public about global warming, with the goal of creating the political will necessary for the United States to take the lead in efforts to lower global carbon emissions. It is an inspiring film, and is decidedly non-partisan in its outlook (though there are a few subtle references to the Bush administration’s lack of leadership on this and other environmental issues). Since Gore is rumored to be a fan of RealClimate, we thought it appropriate to give our first impressions. Much of the footage in Inconvenient Truth is of Al Gore giving a slideshow on the science of global warming. How well does the film handle the science? There are a few scientific errors that are important in the film.
Facts on global warming, climate change and geospatial technologies Some Facts: The Rising Temperature April 2017 was the second-warmest April in 137 years of modern record-keeping, according to NASA‘s Goddard Institute for Space Studies (GISS).In 2016, Earth’s average surface temperature hit a record level for the third consecutive year since records began in 1880.The global average temperature was about 1.1 degree Celsius (1.98 Fahrenheit) higher than the pre-industrial era. This is when mankind’s mass burning of coal, and later oil and gas, started hiking levels of heat-trapping CO2 in the atmosphere. The Melting Ice Arctic summer sea ice shrank to 4.14 million square kilometers (1.6 million square miles) in 2016 — the second-lowest after 2012, when it reached 3.39 million km2.The Arctic Ocean could be ice-free in summer as early as 2030.On the other extreme of the world, Antarctica, sea ice last year hit its lowest extent ever recorded by satellites.

Stop climate change Deeply complex, the climate system drives wind, water, and warmth around our beautiful blue planet, nurturing all life. But now our climate is changing fast. The cause is an old, broken energy system that pollutes our air and water, drives inequality and destroys priceless landscapes. We really have to change; we have only a limited time to act. Join us as we fight to end polluting coal, oil, gas and nuclear projects. Climate affects all life on Earth Our climate is the engine for life support systems that sustain and nurture us all. The climate is changing fast Sea levels are rising, glaciers are melting, and coral reefs are bleaching. Climate change threatens to unravel Earth's complex web of life, and puts livelihoods, coastal cities and food production at risk. The cause of climate change is certain A dirty energy system, fuelled by coal, oil, gas and nuclear power, has failed us. The polluters profit, while the rest of us pay the price. 100% renewable energy is the key
Lake Michigan mostly frozen with ‘shelf’ ice BY HANNAH LUTZ February 14, 2014 1:42PM In this Dec. 26, 2013 photo provided by the U.S. Coast Guard the icebreaker Mackinaw maintains a shipping lane on the St. storyidforme: 62095103 tmspicid: 22412113 fileheaderid: 10712332 Updated: March 17, 2014 11:28AM Lake Michigan looked a bit like a giant ice skating rink this week. As of Thursday, more than 80 percent of the water was frozen. But those who want to practice their triple axel on the lake should think twice. It is still unsafe to walk on, National Weather Service Meteorologist Kevin Birk said. “There have even been cases when the winds will shift, and the ice itself will move,” Birk said. Ice coverage for the five great lakes combined reached about 88 percent Thursday, according to according to the Great Lakes Environmental Research Lab. The “shelf” ice on Lake Michigan is much weaker than the sheet ice on inland lakes, officials said. “It’s not stable and cave-ins have occurred recently. But Gill said the ice isn’t all bad.
Goals for a Critical Thinking Curriculum An Outline of Goals for a Critical Thinking Curriculum and Its Assessment 1Robert H. Ennis, University of Illinois, UC (Revised 6/20/02) E-mail: firstname.lastname@example.org Web site: Critical thinking, as the term is generally used these days, roughly means reasonable and reflective thinking focused on deciding what to believe or do. 2 In doing such thinking, one is helped by the employment of a set of critical thinking dispositions and abilities that I shall outline, and that can serve as a set of comprehensive goals for a critical thinking curriculum and its assessment. It is only a critical thinking content outline. Examples, qualifications, and more detail can be found in some items listed at the end. Dispositions Ideal critical thinkers are disposed to 1. 2. 3.

What Causes Global Warming? | Planetsave Droughts, lengthy hot spells, heavy downpours, floods, and other extreme weather events are occurring more frequently and intensely every year. Around the world, research teams are analyzing these trends, noting the changes in temperature, rainfall, ice mass, sea level, and many other variables recorded by weather measuring devices. The trends are undeniable: the Earth is getting warmer. Compiled by a team of over 300 experts from the most recent accumulation of data over three years, the 2014 National Climate Assessment (NCA), Climate Change Impacts in the United States, was required by Congress to provide clear answers to these important questions. The 2014 National Climate Assessment Overseen by a Federal Advisory Committee of 60 members, the 2014 NCA report is able to help us see what is actually happening to our environment.

Cool Antarctica, pictures of Antarctica, information and travel guide Lake Superior nearing rare ice-over By John MyersForum News Service Posted: 02/06/2014 12:01:00 AM CST | Updated: 3 months ago DULUTH, Minn. -- A frigid winter is pushing Lake Superior toward a complete ice-over for the first time since 1996, though there's still a ways to go before you can skate from Duluth to the Soo Locks. Lake Superior had at least some ice across an estimated 91 percent of its surface as of Thursday, according to the Great Lakes Environmental Research Laboratory. That compares with the 40-year average annual Lake Superior ice coverage for February of just 30 percent. George Leshkevich has been tracking Great Lakes ice for the National Oceanic and Atmospheric Administration Great Lakes Environmental Research Laboratory since 1973. So far, this winter has had among the most rapid ice buildups of his tenure. The widespread ice in January and early February this year "wouldn't have been anomalous back in the '70s or with some of the winters in the mid-'90s.
