I agree that , over the planet, most areas can show sea level rises and GW data, but, like so many things we assert, Im not certain we can yet attribute it to humans. Actually, if you look at atmospheric CO2 since the Mesozoic, we see that the CO2 level is dropping markedly, and this recent rise may be an artifact.
Carbon that had been trapped SINCE THE MESOZOIC in fossil fuels. You bet we warming the planet.
My faith in human beings "getting it" is slipping away.
Whether Im right or youre right- most of the world isnt doing **** to a phenom that may or may not be under our control. We can do some relatively minor adjustments that have shown to yield big results.
But the massive ice melt occurring in the Arctic has introduced a lot of cold, fresh water into the mix, and it's not behaving the same as cold salt water. It's preventing the sinking that usually happens with cold water, as fresh water is less dense than salt water, and that could be weakening the circulation.
"The fact that a record-hot planet Earth coincides with a record-cold northern Atlantic is quite stunning," Stefan Rahmstorf, one of the authors of the study published in Nature Climate Change, told the Washington Post. "There is strong evidence — not just from our study — that this is a consequence of the long-term decline of the Gulf Stream System, i.e. the Atlantic ocean’s overturning circulation AMOC (Atlantic Meridional Overturning Circulation), in response to global warming."
Rahmstorf also told the Washington Post he doesn't expect the blob to remain at record cold levels indefinitely, though the circulation should continue to decline. Everything is connected, and climate scientists believe that connection will drive temperatures, and sea levels, higher and higher.
They have been measuring Arctic sea ice by satellite for about 35 years.
Six Thousandths Of One Percent (0.006%) More Of The World’s Ice Melted This Summer — ‘At this rate it’ll take 166 years to see a 1% reduction. This is like taking a glass of ice from a frozen swimming pool. The number is so small that it is outside the statistical margins of certainty’
“Every year since 2007 has seen more than 10 million square kilometers of seasonal ice melt, reflecting both a transition towards thinner winter ice that melts out more easily in summer as well as changes in the Arctic climate that foster more ice melt each year,” said NSIDC senior scientist Julienne Stroeve.
In addition to an earlier and record-low maximum, early ice retreat and a fast July and August rate of ice loss contributed to this year’s low minimum extent. Strong winds from the eastern Beaufort Sea contributed to earlier than average melt onset and led to the early development of open water in the Beaufort Sea and along the coast of Canada. The pace of seasonal ice loss also picked up rapidly in July, with Arctic-wide temperatures reaching the second highest during the satellite record (with 2007 ranked as the highest). By the end of July, the fast pace of ice loss during the month resulted in the 2015 extent falling within 550,000 square kilometers (212,000 square miles) of the 2012 record low extent, and tracked below the levels recorded for 2013 and 2014. However, temperatures for August were not particularly warm, and extent ended up fourth lowest.
“Another characteristic of this summer was further loss of the thicker multiyear portion of the ice pack. In the past, most of this multiyear ice was too thick and compact to melt completely, but now it’s more vulnerable,” said Walt Meier, research scientist at the NASA Goddard Space Flight Center. Meier is an affiliate scientist at NSIDC and is part of the Arctic Sea Ice News and Analysis team.
“Ten years ago this would have been an astonishing summer of ice melt,” said Ted Scambos, NSIDC’s lead scientist. “Now it is just another season in a decade of low years.”
That is not a minimum for measuring climate change, it is only the duration from one major kind of chancge to the next similar point in the next cycle,
Whilst Ice Ages have tended to last for up to 100,000 years, the intervening interglacial periods have usually been much shorter in duration, at around 10,000 years in length....The last interglacial occurred about 120,000 years ago. Today, the Earth's climate is again within an interglacial period, although the orbital theory of climate change, which explains the glacial-interglacial transitions, predicts that we may be coming towards its end. Indeed, during the 1960s, many scientists suggested that the observed fall in Northern Hemisphere temperatures at that time reflected the gradual onset of a new Ice Age.
The current estimate is that this interglacial has at least 10000 years to go.
The amount of solar radiation (insolation) in the Northern Hemisphere at 65° N seems to be related to occurrence of an ice age. Astronomical calculations show that 65° N summer insolation should increase gradually over the next 25,000 years. A regime of eccentricity lower than the current value will last for about the next 100,000 years. Changes in northern hemisphere summer insolation will be dominated by changes in obliquity ε. No declines in 65° N summer insolation, sufficient to cause a glacial period, are expected in the next 50,000 years.....
More recent work by Berger and Loutre suggests that the current warm climate may last another 50,000 years.
