Lewis Page: New science upsets calculations on sea level rise, climate change (Ice sheet melt massively overestimated, satellites show)

A new analysis of data from dedicated satellites shows that one of the main factors predicted to drive rising sea levels in future has been seriously overestimated, with major implications for climate talks currently underway in Doha.

The new methods involve filtering out noise from the data produced by the Gravity Recovery And Climate Experiment (GRACE) spacecraft, sent into orbit with the aim of finding out just how much ice is melting from the world's ice sheets and glaciers. Such water then runs off into the sea, providing one of the main potential drivers of sea level rise - which is itself perhaps the main reason to worry about climate change.

"GRACE data contain a lot of signals and a lot of noise. Our technique learns enough about the noise to effectively recover the signal, and at much finer spatial scales than was possible before," explains professor Frederik Simons of Princeton uni. "We can 'see through' the noise and recover the 'true' geophysical information contained in these data. We can now revisit GRACE data related to areas such as river basins and irrigation and soil moisture, not just ice sheets."

Lewis Page: Global warming still stalled since 1998, WMO Doha figures show

'We're looking into this thing which is NOT HAPPENING'

Figures released by the UN's World Meteorological Organisation indicate that 2012 is set to be perhaps the ninth hottest globally since records began - but that planetary warming, which effectively stalled around 1998, has yet to resume at the levels seen in the 1980s and early 1990s.

The WMO figures are produced by averaging those from the three main climate databases: those of NASA, the US National Oceanic and Atmospheric Administration (NOAA) and the British one compiled jointly by the Met Office and the University of East Anglia.

The 2012 figure for the year so far stands at 14.45°C. If that were the figure for the full year, it would be cooler than 1998 (14.51°C) and most of the years since then (full listing from the Met Office here).

The official position of the climate establishment is that global warming is still definitely on and the flat temperatures seen for the last 14 years or so are just a statistical fluke of the sort to be expected when trying to measure such a vast and noisy signal as world temperatures with such precision. (The global warming since 1950 is assessed as just half a degree, a difficult thing to pick out when temperatures everywhere go up and down by many degrees every day and even more over a year.)

Lewis Page: SEAS WILL RISE due to CO2 ... but not for centuries

Thursday, October 4th 2012, 7:38 AM EDT

Nothing much doing until 2200AD at the earliest

Not a problem for your children, or theirs (recurring)

A new, first-of-its-kind comprehensive scientific analysis has shown that there is little to fear from rising sea levels driven by global warming. The likelihood is that the 21st century will see rises much like those of the 20th, and even in the worst possible case sea levels in 2100 will be far below those foreseen by alarmists.

There's a catch, of course: on a timescale of many centuries, serious alarmist-type rises in sea levels are to be expected. Even if humanity ceases all carbon emissions right now, in the year 3000AD the seas will have risen by 1.1m, according to Professor Philippe Huybrechts and his team.

As most Reg readers know, the various land-based ice sheets and glaciers of planet Earth today hold enormous amounts of water. As and when they melt, the potential is there for huge rises in sea level. This has led climate-alarmist campaigners to suggest in reputable peer-reviewed journals that "scientists" generally expect the seas to rise by a metre or more - flooding millions of homes - as soon as the year 2100.

Lewis Page: Salt marshes will suck CO2 from air faster and faster as seas rise

Runaway global warming gets more negative feedback

Salt marshes and similar types of coastal terrain could act naturally to fight global warming by absorbing increasing amounts of carbon in a warming world, scientists have found. Even better, salt marshes' carbon-sequestering effects would actually be increased sea-level rise.

Salt marshes, mainly made up of specialised grasses and their root systems, are a common type of coastal environment. They trap silt, serving to build up the elevation of the coastline and so resist storms and flooding. As the seas rise, the marsh rises too, as professor Matt Kirwan (Virginia uni) explains:

“One of the cool things about salt marshes is that they are perhaps the best example of an ecosystem that actually depends on carbon accumulation to survive climate change: The accumulation of roots in the soil builds their elevation, keeping the plants above the water,” says the prof.

According to a statement announcing Kirwan and his colleagues' new research into salt-marsh carbon effects:

Lewis Page: Ice core shows Antarctic Peninsula warming is nothing unusual

Move along, nothing to see here

Press release flatly contradicts what boffins said

New ice core data from the Antarctic Peninsula has revealed that temperatures in the region during the past 10,000 years have often been higher than they are today, and that warming of the sort seen there recently has also occurred in the pre-industrial past.

The new data are derived from a massive new 364m-long core extracted from the ice sheet lying on top of James Ross Island towards the northern tip of the Antarctic Peninsula in the freezing Weddell Sea. The core was extracted by scientists from the British Antarctic Survey, assisted by French boffins, who reached the area courtesy of the Royal Navy ice-patrol ship HMS Endurance and her helicopters.

The mighty core has allowed analysing boffins to reconstruct local temperatures and snowfall way back to the end of the last ice age. The info is of particular interest as the Peninsula has warmed up rather quickly over the last 50 years or so, and is bucking the overall Antarctic trend which has seen vast new expanses of sea ice appear around the coasts of the austral continent. Thus it is that the Ross Island ice core results have made it into this week's edition of agenda-setting boffinry mag Nature.

So what have we got?

Lewis Page: Amount of meat we eat will barely affect future climate change

Look at the numbers, forget the spin

For the last few days, the mainstream British media have been assuring us that rich westerners must seriously cut down the amount of meat we eat - and the rest of the world must keep to its current meat-light diet - in order to stave off planetary apocalypse. But what are the facts?

The reports are all based on this paper in the journal Energy and Environmental Science. It was actually published a couple of weeks ago, but nobody noticed: the flurry of interest, as is normal in "science news", stems from a press release issued this week. The press release offers a clear message:

New research from the University of Exeter shows that if today’s meat-eating habits continue, the predicted rise in the global population could spell ecological disaster.

This has generally been simplified along the lines of "Eat less meat to save planet, researchers warn". And to be fair, that does indeed seem to be in line with the personal agenda of the researchers who wrote the paper.

Lewis Page: Amount of ice in Bering Sea reaches all-time record

Hippies get it wrong again

The amount of floating ice in the Arctic's Bering Sea - which had long been expected to retreat disastrously by climate-Cassandra organisations such as Greenpeace - reached all-time record high levels last month, according to US researchers monitoring the area using satellites.

The US National Snow and Ice Data Center announced last week that ice extent in the Bering for the month of March has now been collated and compared, and is the highest seen since records began. The NSIDC boffins said in a statement:

As winds from the north pushed Arctic ice southward through the Bering Strait, the ice locked together and formed a structurally continuous band known as an ice arch, which acts a bit like a keystone arch in a building. The ice arch temporarily held back the ice behind it, but as the winds continued, the arch failed along its southern edge, and ice cascaded south through the strait into the Bering Sea. Sea ice also piled up on the northern coast of St Lawrence Island, streaming southward on either side of it.

This contrasts sharply with the grim future for the Bering predicted by Greenpeace. Thirteen years ago in 1999, the hippies* had this to say:

Lewis Page: Atmospheric CO2 set to SOAR from 0.0004 to 0.0007 - OECD

Saturday, March 17th 2012, 4:36 AM EDT

Co2sceptic (Site Admin)

The Organisation for Economic Co-operation and Development has issued a forecast saying that - unless something big changes - the level of CO2 in the Earth's atmosphere is set to rise significantly as the planet's population swells and its poorer nations start to develop their economies and use more energy.

In a new document published yesterday, the economic alliance says that the human race is expected to increase in numbers from 7+ billion today to more than 9 billion in 2050. However the global economy is expected to recover from its present troubles and quadruple in size, meaning that overall the human race will be richer and more developed.

This in turn is expected to lead to a significantly increased demand for energy, up 80 per cent from today's: and the OECD says that - so far from the predictions of Peak Oil - without massive worldwide legislative action, this heightened demand will be met by a similar mix of technologies to today's. That is, 85 per cent fossil fuel, 10 per cent renewables (much of which will be "biofuel" wood burning, perhaps not really renewable or sustainable in many cases) and the remaining 5 per cent nuclear.
