Isen på antarktis smelter, længere er den ikke.

Temperatu pt. ligger ca. 0,5°C højere end 1979-2000 baseline.

Så kan du smide om dig med nok så mange tal og prøve at lyde klog, men det ændrer ikke noget ved ovenstående.

Og hvis du poster den graf 25 gange, så viser den stadig at isen i antarktis smelter...

Se sidste 25 års afsmeltning fra antarktis har givet 8mm.
Med lidt tiltagende afsmeltning,så giver det måske 1cm per 100 år. Som sagt, lige der kan jeg ikke se en katastrofe.
Men en tydelig indikator på AGW.

Ja alle forudsigelser klimaindustrien er kommet med de sidste 30 år har alle været vildt overdreven og har slået fejl med flere armslængder.

Og selv om menneskeheden har pumpet over 60 % af den menneskelige co2 op i atmosfæren de sidste 30 år så udviser drivhuseffekten ikke nogen evne til at øge energiafsætningen i jordens klimasystemer. Og hvorfor tror nogle så at afsmeltningen skulle kunne øges. En afsmeltning som alt andet lige kræver energi

More than 90 percent of the warming that has happened on Earth over the past 50 years has occurred in the ocean. Recent studies estimate that warming of the upper oceans accounts for about 63 percent of the total increase in the amount of stored heat in the climate system from 1971 to 2010, and warming from 700 meters down to the ocean floor adds about another 30 percent.
Less than a watt per square meter might seem like a small change, but multiplied by the surface area of the ocean (more than 360 million square kilometers), that translates into an enormous global energy imbalance. It means that while the atmosphere has been spared from the full extent of global warming for now, heat already stored in the ocean will eventually be released, committing Earth to additional warming in the future.

In the present, warming of ocean water is raising global sea level because water expands when it warms. Combined with water from melting glaciers on land, the rising sea threatens natural ecosystems and human structures near coastlines around the world. Warming ocean waters are also implicated in the thinning of ice shelves and sea ice, both of which have further consequences for Earth's climate system. Finally, warming ocean waters threaten marine ecosystems and human livelihoods. For example, warm waters jeopardize the health of corals, and in turn, the communities of marine life that depend upon them for shelter and food. Ultimately, people who depend upon marine fisheries for food and jobs may face negative impacts from the warming ocean.

Nå, da.

At den opsparede energi i Oceanerne senere skulle virke til en øget accelererende opvarmning, vidner om en total mangel på viden om hvordan klimasystemerne og drvhuseffekten virker.

Det er ligeledes klart, at varmen fordeles ikke jævnt og varme, der forsvinder dybere ned i oceanerne, kan senere vende tilbage til overfladen og give øget opvarmning.

Og når CO2 indhold i atmosfæren bliver ved med at stige, så når du aldrig balancen og temperaturen bliver ved med at stige.

Er der flere spørgsmål ift. nano materialer jeg kan hjælpe med?

Det er et faktum, der end ikke kan diskuteres, medmindre man bare er benægter og derfor er udenfor almindelig rækkevidde forsåvidt angår accept af den virkelighed, der kan måles og registreres.

A new study shows that increased heat from Arctic rivers is melting sea ice in the Arctic Ocean and warming the atmosphere.

The study published this week in Science Advances was led by the Japan Agency for Marine-Earth Science and Technology, with contributing authors in the United States, United Arab Emirates, Finland and Canada.

According to the research, major Arctic rivers contribute significantly more heat to the Arctic Ocean than they did in 1980. River heat is responsible for up to 10% of the total sea ice loss that occurred from 1980 to 2015 over the shelf region of the Arctic Ocean. That melt is equivalent to about 120,000 square miles of 1-meter thick ice.

"If Alaska were covered by 1-meter thick ice, 20% of Alaska would be gone," explained Igor Polyakov, co-author and oceanographer at the University of Alaska Fairbanks' International Arctic Research Center and Finnish Meteorological Institute.

Rivers have the greatest impact during spring breakup. The warming water dumps into the ice-covered Arctic Ocean and spreads below the ice, decaying it. Once the sea ice melts, the warm water begins heating the atmosphere.

The research found that much more river heat energy enters the atmosphere than melts ice or heats the ocean. Since air is mobile, this means river heat can affect areas of the Arctic far from river deltas.

The impacts were most pronounced in the Siberian Arctic, where several large rivers flow onto the relatively shallow shelf region extending nearly 1,000 miles offshore. Canada's Mackenzie River is the only river large enough to contribute substantially to sea ice melt near Alaska, but the state's smaller rivers are also a source of heat.

Polyakov expects that rising global air temperatures will continue to warm Arctic rivers in the future. As rivers heat up, more heat will flow into the Arctic Ocean, melting more sea ice and accelerating Arctic warming.

Rivers are just one of many heat sources now warming the Arctic Ocean. The entire Arctic system is in an extremely anomalous state as global air temperatures rise and warm Atlantic and Pacific water enters the region, decaying sea ice even in the middle of winter. All these components work together, causing positive feedback loops that speed up warming in the Arctic.

"It's very alarming because all these changes are accelerating," said Polyakov. "The rapid changes are just incredible in the last decade or so."
