GLOBAL Cooling A Reality But Technology And CO2 Will Help Earth Survive

AN IMPORTANT and timely read Via The Times – MATT RIDLEY (Climatism bolds)

RECORD cold in America has brought temperatures as low as minus 44C in North Dakota, frozen sharks in Massachusetts and iguanas falling from trees in Florida. Al Gore blames global warming, citing one scientist to the effect that this is “exactly what we should expect from the climate crisis”. Others beg to differ: Kevin Trenberth, of America’s National Centre for Atmospheric Research, insists that “winter storms are a manifestation of winter, not climate change”.

Forty-five years ago a run of cold winters caused a “global cooling” scare. “A global deterioration of the climate, by order of magnitude larger than any hitherto experienced by civilised mankind, is a very real possibility and indeed may be due very soon,” read a letter to President Nixon in 1972 from two scientists reporting the views of 42 “top” colleagues. “The cooling has natural causes and falls within the rank of the processes which caused the last ice age.” The administration replied that it was “seized of the matter”.

In the years that followed, newspapers, magazines and television documentaries spoke of the coming ice age. The CIA reported a “growing consensus among leading climatologists that the world is undergoing a cooling trend”.

This alarm about global cooling is largely been forgotten, but it has not entirely gone away. Valentina Zharkova of Northumbria University has suggested that a quiescent sun presages another Little Ice Age like that of 1300-1850. I’m not persuaded. Yet the argument that the world is slowly slipping back into a proper ice age after 10,000 years of balmy warmth is in essence true. Most interglacial periods, or times without large ice sheets, last about that long, and ice cores from Greenland show that each of the past three millennia was cooler than the one before.

However, those ice cores, and others from Antarctica, can now put our minds to rest. They reveal that interglacials start abruptly with sudden and rapid warming but end gradually with many thousands of years of slow and erratic cooling. They have also begun to clarify the cause. It is a story that reminds us how vulnerable our civilisation is. If we aspire to keep the show on the road for another 10,000 years, we will have to understand ice ages.

The oldest explanation for the coming and going of ice was based on carbon dioxide. In 1895 the Swede Svante Arrhenius, one of the scientists who first championed the greenhouse theory, suggested that the ice retreated because carbon dioxide levels rose, and advanced because they fell. If this were true, then industrial emissions could head off the next ice age. There is indeed a correlation in the ice cores between temperature and carbon dioxide, but inconveniently it is the wrong way round: carbon dioxide follows rather than leads temperature downward when the ice returns.

A Serbian named Milutin Milankovich, writing in 1941, argued that ice ages and interglacials were instead caused by changes in the orbit of the Earth around the sun. These changes, known as eccentricity, obliquity and precession, sometimes combined to increase the relative warmth of northern hemisphere summers, melting ice caps in North America and Eurasia and spreading warmth worldwide.

RECORD COLD

Planes wait at the gates outside terminal five at New York’s John F. Kennedy International Airport in the heavy snow.

IN 1976 Nicholas Shackleton, a Cambridge physicist, and his colleagues published evidence from deep-sea cores of cycles in the warming and cooling of the Earth over the past half million years which fitted Milankovich’s orbital wobbles. Precession, which decides whether the Earth is closer to the sun in July or in January, is on a 23,000-year cycle; obliquity, which decides how tilted the axis of the Earth is and therefore how warm the summer is, is on a 41,000-year cycle; and eccentricity, which decides how rounded or elongated the Earth’s orbit is and therefore how close to the sun the planet gets, is on a 100,000-year cycle. When these combine to make a “great summer” in the north, the ice caps shrink.

Game, set and match to Milankovich? Not quite. The Antarctic ice cores, going back 800,000 years, then revealed that there were some great summers when the Milankovich wobbles should have produced an interglacial warming, but did not. To explain these “missing interglacials”, a recent paper in Geoscience Frontiers by Ralph Ellis and Michael Palmer argues we need carbon dioxide back on the stage, not as a greenhouse gas but as plant food.

The argument goes like this. Colder oceans evaporate less moisture and rainfall decreases. At the depth of the last ice age, Africa suffered long mega-droughts; only small pockets of rainforest remained. Crucially, the longer an ice age lasts, the more carbon dioxide is dissolved in the cold oceans. When the level of carbon dioxide in the atmosphere drops below 200 parts per million (0.02 per cent), plants struggle to grow at all, especially at high altitudes. Deserts expand. Dust storms grow more frequent and larger. In the Antarctic ice cores, dust increased markedly whenever carbon dioxide levels went below 200 ppm. The dust would have begun to accumulate on the ice caps, especially those of Eurasia and North America, which were close to deserts. Next time a Milankovich great summer came along, and the ice caps began to melt, the ice would have grown dirtier and dirtier, years of deposited dust coming together as the ice shrank. The darker ice would have absorbed more heat from the sun and a runaway process of collapsing ice caps would have begun.

All of human civilisation happened in an interglacial period, with a relatively stable climate, plentiful rainfall and high enough levels of carbon dioxide to allow the vigorous growth of plants. Agriculture was probably impossible before then, and without its hugely expanded energy supply, none of the subsequent flowering of human culture would have happened.

That interglacial will end. Today the northern summer sunshine is again slightly weaker than the southern. In a few tens of thousands of years, our descendants will probably be struggling with volatile weather, dust storms and air that cannot support many crops. But that is a very long way off, and by then technology should be more advanced, unless we prevent it developing. The key will be energy. With plentiful and cheap energy our successors could thrive even in a future ice age, growing crops, watering deserts, maintaining rainforests and even melting ice caps.

Snowfall on Alaska mountains has doubled – climate change blamed

Unprecedented findings strengthen connections between winter storms and tropical waters

HANOVER, N.H. – December 19, 2017 – Snowfall on a major summit in North America’s highest mountain range has more than doubled since the beginning of the Industrial Age, according to a study from Dartmouth College, the University of Maine, and the University of New Hampshire.

The research not only finds a dramatic increase in snowfall, it further explains connections in the global climate system by attributing the record accumulation to warmer waters thousands of miles away in the tropical Pacific and Indian Oceans.

The research demonstrates that modern snowfall in the iconic Alaska Range is unprecedented for at least the past 1200 years and far exceeds normal variability.

“We were shocked when we first saw how much snowfall has increased,” said Erich Osterberg, an assistant…

It’s been dubbed “the Blizzard of Oz”, and powder hounds could not be happier.

Australia’s ski resorts in the Snowy Mountains, in New South Wales, and Victoria’s Alpine National Park were covered with the white stuff this morning after both reported the best falls of the season at the weekend.

More than 1.15 metres of snow has been dumped at Thredbo from Friday morning to 6:00am today.

BUT, wasn’t ‘snowfall’ meant to be “a very rare and exciting event.” And, that “Children just aren’t going to know what snow is.” ?

Those expert predictions made back in 2000 by esteemed climatologist Dr David Viner of the UK’s CRU (Climate Research Unit):

From the Independent’s most cited article: “Snowfalls are now just a thing of the past” by Charles Onians:

However, the warming is so far manifesting itself more in winters which are less cold than in much hotter summers. According to Dr David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia,within a few years winter snowfall will become “a very rare and exciting event”.

“Children just aren’t going to know what snow is,” he said.

Australia’s “premier” scientific government organisation, the (warmist) CSIRO, jumped on the “end of snow” bandwagon in August 2003:

Simulations of future snow conditions in the Australian alpine regions were prepared for the years 2020 and 2050…

Conclusion:

The low impact scenario for 2020 has a minor impact on snow conditions. Average season lengths are reduced by around five days. Reductions in peak depths are usually less than 10%, but can be larger at lower sites (e.g. Mt Baw Baw and Wellington High Plains).

The high impact scenario for 2020 leads to reductions of 30-40 days in average season lengths.  At higher sites such as Mt Hotham, this can represent reductions in season duration of about 25%, but at lower sites such as Mt Baw Baw the reduction can be more significant (up to 60%)…

We have very high confidence (at least 95%) that the low impact scenarios will be exceeded and the high impact scenarios will not be exceeded.

Skiing in July? It could happen this year, but California’s days of bountiful snow are numbered.

After five years of drought and water restrictions, the state is reeling from its wettest winter in two decades. Moisture-laden storms have turned brown hillsides a lush green and state reservoirs are overflowing. There’s so much snow, Mammoth Mountain resort plans to be open for business on Fourth of July weekend.

The Sierra Nevada snowpack, which provides 60 percent of the state’s water via a vast network of dams and reservoirs, has already been diminished by human-induced climate change…

Snowpack on the Sierra Nevada provides one-third of the water consumed by California citizens, farmers, and businesses each year. For the first time in at least five years, there should be more than enough of it.

According to the California Department of Water Resources (DWR), the water stored as snow in the Sierra Nevada range was 185 percent of the long-term average for the beginning of March. One year ago, it was 83 percent of the norm. According to the latest measurements from 98 ground-based stations, the average snow-water equivalent in the mountains was 45.5 inches as of March 1, 2017. Snow-water equivalent is an estimate of how much…
