Vad är växthuseffekten? What the World Would Look Like if All the Ice Melted. This story appears in the September 2013 issue of National Geographic magazine.
The maps here show the world as it is now, with only one difference: All the ice on land has melted and drained into the sea, raising it 216 feet and creating new shorelines for our continents and inland seas. There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all. If we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58. North America The entire Atlantic seaboard would vanish, along with Florida and the Gulf Coast.
South America The Amazon Basin in the north and the Paraguay River Basin in the south would become Atlantic inlets, wiping out Buenos Aires, coastal Uruguay, and most of Paraguay.

Climate change could displace up to a quarter of a billion people. DW: In Europe we're seeing the arrival of hundreds of thousands of refugees, mostly from war-torn countries.
Some are calling it a "migration crisis," but is this the new normal? Is this the kind of mass migration that climate change could cause? Scott Leckie: Well, we hope that's not the new normal and we believe, through what we've done in 15 or 20 different countries, that most people who will leave their homes because of climate change will aim initially to stay within the borders of their own country.
Only in the most dramatic cases will people actually try to flee across borders. How many people globally are in danger of having to leave their homes because of climate change-related problems, like rising sea levels or droughts? What's Really Warming the World? Climate deniers blame natural factors; NASA data proves otherwise. Climate scientists tend not to report climate results in whole temperatures. Instead, they talk about how the annual temperature departs from an average, or baseline. They call these departures "anomalies. " They do this because temperature anomalies are more consistent in an area than absolute temperatures are.
For example, the absolute temperature atop the Empire State Building may be different by several degrees than the absolute temperature at New York’s LaGuardia Airport. NASA To Invest In Eco-Friendly Commercial Supersonic Jets. Improved Data Set Shows No Global Warming ‘Hiatus’ National and international studies have shown that the Earth is warming, and with this warming, other changes are occurring, such as an increasing incidence of heat waves, heavy downpours and rising sea levels.
In its Fifth Assessment Report in 2013, the Intergovernmental Panel on Climate Change found that the temperature of the Earth increased at a rate of 0.22 Fahrenheit (0.12 Celsius) per decade from 1951-2012. It also found that the rate of warming from 1998-2012 had slowed to 0.09F (0.05C) per decade. This slowdown in the rate of warming, called a “hiatus,” was initially perplexing to climate scientists.
It was inconsistent with expectations that global temperatures would rise at similar or even greater rates than they had in the latter half of the 20th century as the concentration of greenhouse gases in the atmosphere continued to rise. Top 10 Eco-friendly Substitutes for Plastic. All newborn mammals survive on it.
Without it, there would be no ice cream. There's really no denying the value, or pleasure, of milk. Now scientists say it could help to produce a biodegradable plastic for furniture cushions, insulation, packaging and other products. What if there were no bees? It's a beautiful day for a picnic, but minutes after you spread a blanket on the grass and unpack an impressive selection of sandwiches, fruit salad and a show-stopping cherry pie, you discover an uninvited guest.
A bee is making the rounds, buzzing around your head and scaring all your friends. You're about to swipe at the winged interloper with your shoe, but then think better of it. It's a good thing, too, because bee populations are dwindling. Consider these United States Department of Agriculture (USDA) survey results, based on 21.7 percent of the 2.6 million bee colonies in the United States. During the 2013-2014 winter, more than 23 percent of honeybees in the managed colonies included in the survey had died. And honeybees aren't the only bees at risk. Bees rely on pollen and nectar from plants for food. Rising Seas - Interactive: If All The Ice Melted.
