Here's What The World Will Look Like Once All The Ice Melted. Terrifying! We learned last year that many of the effects of climate change are irreversible.
Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century. As National Geographic showed us in 2013, sea levels would rise by 216 feet if all the land ice on the planet were to melt. Humans Are Changing the Climate 170x Faster Than Natural Forces. A New Equation Scientists have devised a new mathematical equation that allows them to determine just how much humans are affecting the climate.
According to the researchers, global temperatures have decreased by an average of 0.01 Celsius per century over the last 7,000 years. This figure is what they considered the baseline rate. In the last 45 years however, trends show that it has increased at 1.7 Celsius per century, due to greenhouse gas emissions. In the paper, published in the journal The Anthropocene Review, the researchers go on to explain that across billions of years, Earth’s climate has been dependent on astronomical and geophysical forces, as well as internal dynamics of the planet. Massive hurricane-force Atlantic storm to push abnormally mild air toward North Pole.

(National Weather Service Ocean Prediction Center) A gigantic, powerhouse winter storm is charging through the North Atlantic and promises to flood the high Arctic with abnormally mild air. Arctic temperatures have blown past previous record highs in recent months, and this surge of (relative) warmth is just the latest in a long series that has amazed scientists. Deze kerel hoorde iets breken in de gletsjer en verstijfde. Wat hij toen zag, ging zijn ergste nachtmerrie te boven.
Amerikaanse fotograaf James Balog en zijn team reisden in Groenland rond.
Ze hadden camera's opgesteld rondom de noordpoolcirkel en brachten meerdere jaren door met het verzamelen van de veranderingen in het ijs. Risk för oväntade effekter i Arktis. 80,000 Reindeer Have Starved Тo Death Аs Arctic Sea Ice Disappears Аnd THIS is WHY! – SPIRIT EGG. Share Tweet Email Unusual weather patterns in Arctic Russia have caused more than 80,000 reindeer to starve to death over the past 10 years.
And that die-off hasn’t been gradual – 20,000 deer have been killed in 2006, and 61,000 animals have starved to death in 2013. Global Climate Page.

BBC iWonder - Did climate change make us intelligent? Global Carbon Atlas. Thermohaline Circulation - Fact Sheet by Stefan Rahmstorf. As opposed to wind-driven currents and tides (which are due to the gravity of moon and sun), the thermohaline circulation (Fig. 1) is that part of the ocean circulation which is driven by density differences.
Sea water density depends on temperature and salinity, hence the name thermo-haline. The salinity and temperature differences arise from heating/cooling at the sea surface and from the surface freshwater fluxes (evaporation and sea ice formation enhance salinity; precipitation, runoff and ice-melt decrease salinity). Heat sources at the ocean bottom play a minor role. Graph of the Day: World has warmest winter on record. [Not just the Arctic experiences the warmest winter on record – this goes for the entire globe, new NASA data show.
We now have the hottest winter on record straight after the hottest summer on record.] Just when you thought positive global monthly average temperature deviations can’t get any larger (December 2015, +1,11C) positive global monthly average temperature deviations do indeed grow larger still (January 2016, +1,13C) – as newly released NASA data show. January 2016 is the fourth month in a row that saw world average temperatures of more than +1 degree Celsius – starting from October 2015. And just to be clear, this is not +1 since pre-industrial times, but +1 since 1951-1980 climate average – so a 1 degree temperature rise over ~50 years: (Please lift a couple of rocks in your backyard to see if you can find any sane person that still ‘believes’ our planet is not warming. After 2014 and 2015 records, 2016 set to become hotter still © Rolf Schuttenhelm | www.bitsofscience.org. Study: Mass Gains of Antarctic Ice Sheet Greater than Losses.
An iceberg floats in Disko Bay, near Ilulissat, Greenland, on July 24, 2015.
The massive Greenland ice sheet is shedding about 300 gigatons of ice a year into the ocean, making it the single largest source of sea level rise from melting ice. Credits: NASA/Saskia Madlener Sea level rise is a natural consequence of the warming of our planet. Flooding of Coast, Caused by Global Warming, Has Already Begun. NORFOLK, Va. — Huge vertical rulers are sprouting beside low spots in the streets here, so people can judge if the tidal floods that increasingly inundate their roads are too deep to drive through.
Five hundred miles down the Atlantic Coast, the only road to Tybee Island, Ga., is disappearing beneath the sea several times a year, cutting the town off from the mainland. And another 500 miles on, in Fort Lauderdale, Fla., increased tidal flooding is forcing the city to spend millions fixing battered roads and drains — and, at times, to send out giant vacuum trucks to suck saltwater off the streets. For decades, as the created by human emissions caused land ice to melt and ocean water to expand, scientists warned that the accelerating rise of the sea would eventually imperil the United States’ coastline.
