Global warming slowdown answer lies in depths of Atlantic, study finds

The key to the slowdown in global warming in recent years could lie in the depths of the Atlantic and Southern Oceans where excess heat is being stored – not the Pacific Ocean as has previously been suggested, according to new research.......

...
Ka-Kit Tung, author of the paper and University of Washington professor, said: “The finding is a surprise, since the current theories had pointed to the Pacific Ocean as the culprit for hiding heat. But the data are quite convincing and they show otherwise.”
“We are not downplaying the role of the Pacific. They are both going on [the oceans having an effect on temperatures]; one is short term [the Pacific], one is long term [the Atlantic],” he told the Guardian....
......
Jon Robson, a climate scientist at the University of Reading and who is unconnected to the study, said the new work did not disprove evidence of the Pacific’s role in the warming slowdown.
“The hiatus really is a patchwork problem of lots of different things, volcanoes, the Pacific, the Atlantic. This paper does elevate the Atlantic’s role, which has been largely ignored before. This does suggest a role for the Atlantic but there’s a lot more to it than that,” he told the Guardian......

Stor rabatt för bränslecellsbilar

Japan tror på bränslecellsbilar som framtidens teknik. Enligt premiärminister Shinzo Abe är regeringen beredd att satsa motsvarande tre miljarder kronor i bidrag till bilköpare och mackägare de närmaste åren.

...
Tillverkarna har de senaste åren reducerat kostnaden för att tillverka bränsleceller med 90 procent, genom att minska mängden ädelmetaller och industrialisera processen. Tillsammans med subventionerna gör det att bränslecellsbilar blir ett alternativ till hybrider i Japan.
– Subventionerna ger en enorm drivkraft för försäljningen, men de kommer inte att erbjudas för alltid och jag tror att budskapet här är att vi måste fortsätta att minska kostnaderna, säger Koichi Kojima, ingenjör på Toyota som har varit med i utvecklingen av Toyotas bränslecellsbilar, till Reuters.

Catching Waves in the Arctic

As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell — huge waves that could add a new and unpredictable element to the region.
