The Gulf stream disappears? The sea level is rising because of that? And it is very cold in Northern Europe? German climate researchers have summarized current data on the hot water pump in the Atlantic.
300 billion tons of loss in mass every year: Greenland ice.
He is lacking in any horror scenario about the consequences of global warming: The Gulf stream. So, the gigantic movement of large water masses across the Atlantic ocean towards the North and back again. Or, as the renowned Bremen-based oceanographer Monika Rhein says: “The main component of our hot water heating system, which ensures that we have here in Europe a temperate climate.” What happens if the Gulf is fading power or even break, as some environmentalists warn? Agreed, and that is all: A rising global temperature may weaken the Gulf stream, and in the eternal cycle of warm, salty water to the North washed up in gigantic masses: In Florida such as the Gulf stream brings together about 30 times as much water as all the rivers of the earth.
“The Gulf stream will not disappear completely, but he takes off.”
But he breaks off now? And what does this mean for the climate? Mojib Latif, a climate scientist from Kiel, has written together with the Rhine and other experts, the most important facts on a good 30 pages.
“We do not know whether the Gulf is disappearing stream”. The climate scientist Monika Rhein, and Mojib Latif.
His conclusion: “If we operate in the world, no climate protection, and so much greenhouse gases to emit, as in the time, then Golf could decrease power to 2100 by about 30 percent.” The power disappears so not quite, but its reduction would have dramatic consequences. The temperature in Northern Europe might be sensitive to fall. But to keep in mind Latif, and the Rhine: these are all just vague predictions. Monika Rhein, and has co-authored in the last global Report of the world climate Council (IPCC) four years ago, the Chapter on the oceans, said: “We have only been a good 20 years, with clear methods of measurement. To make really reliable statements on Changes of the circulation in the Gulf stream, it is not enough this time, the System is very complex.” This limitation is both a science important, because, according to Latif: “When I travel around and lectures on climate change, there is often this view in the case of the people of The Gulf stream collapses completely. We can’t say so.”
Greenland the loss of ice mass dramatically
Clear measurable the loss of ice mass in Greenland – with implications also for the Gulf stream. Since the beginning of the measurements in front of a good 20 years, Greenland has lost around 300 billion tons of ice – water, which landed in the ocean and on land. The researchers assume that this could be mitigated by the Gulf stream, because it is freshwater. And this melting water may also lead to in North America and Europe’s coasts the rise in sea level of 20 centimetres.
Latif: Depression in US climate researchers noticeable
Both scientists are, however, certain: the Gulf stream, it is vital that the countries of the earth keep the temperature below two degrees, as is promised in the Paris climate Treaty in 2015.
From this Treaty, US President, Donald Trump, holds a little bit of climate protection is dropped, this year. Latif and the Rhine, are in close contact with their American colleagues, have registered this decision horrified. “The Depression is already noticeable. In the exploration of the sea, many of the US counterparts are leading the way,” says Latif.
And Monika Rhein reported from a conference with ocean researchers recently in New York. Just scientists in the civil service were of great concern, as the Rhine, if you get in the future-money for costly research. “Their Work is often not only important for climate protection, but also for the protection of the American coasts”. It is, however, doubtful whether such an Argument in the case of Trump will be heard.

What happens when the sea temperatures rise?Atlantis 2.0
As global warming progresses, the sea level rise getting faster and faster. While the oceans rose from 2004 to 2010, a total of about 15 mm, so this value is doubled for 2010 to 2016, according to the world Meteorological organization (WMO). Coastal regions and shallow Islands in the Western Pacific are particularly at risk and could sink up to 2100 in the sea.

What happens when the sea temperatures rise?Icebreaker
While the oceans and the atmosphere warming, melting of glaciers and ice caps. In the Northern and southern summer months of 2016, the global sea ice dropped to 4 million square kilometers more than the average since the beginning of the measurements. As a result, more melt water flows in rivers and oceans, making the sea level rise.

What happens when the sea temperatures rise?Losing Nemo
Some ocean regions have warmed by more than three degrees Celsius. The maritime Ecosystems mess. 72 percent of the fish species caught in the northeast Atlantic by bottom trawls, are on the decline in catch and spread. And also tropical species such as clown fish are endangered in their habitat.

What happens when the sea temperatures rise?Coral bleaching
More carbon dioxide in the air also changes the PH of the water. It will be sour. The damage they do to Nemo’s home – the sensitive coral reefs. Also the water temperatures rise to only 3 degrees Celsius, that can mean the death of coral reefs and its inhabitants. Northern parts of the Great Barrier Reef in Australia are already seeing mortality rates of up to 50 percent.

What happens when the sea temperatures rise?Stormy Outlook
If the oceans are warming, there could be more and stronger tropical cyclones. One of these giant towers hurricane Matthew, in October 2016 on the Haitian coast, Cuba, which hit the Bahamas and Florida. The hurricanes claimed more than 1,000 deaths and caused economic damage of € 13.8 billion.

What happens when the sea temperatures rise?Turbulent Air Traffic
There is a strong connection between atmospheric winds and ocean temperatures. Higher water temperatures could cause the Jetstream is stronger. Pilot and then with greater and winds expected. The advantage is that some flights arrive much faster at your destination. The disadvantage is that other flights may take longer and experience more turbulence.
