Global Warming

[Rorschach]

The Roach seems to be suffering from possession. Time to call the priest.

It got so hot in Australia in January that the weather service had to add two new colors to its charts. A few weeks later, at the other end of the planet, new data from the CryoSat-2 satellite showed 80 percent of Arctic sea ice has disappeared. We're not breaking records anymore; we're breaking the planet. In 50 years, no one will care about the fiscal cliff or the Euro crisis. They'll just ask, "So the Arctic melted, and then what did you do?"

Here's the good news: We'll at least be able to say we fought.

Sorry AiA that's a furphy already been covered here.

Antarctic ice sheet melt 'not that unusual', latest ice core shows. Warm slushy spells like the 1990s have happened before

The latest ice-core analysis from the Antarctic shows that nothing unusual in terms of melting is occurring.

In research published yesterday, a large team of scientists used a deep ice core from the Western Antarctic Ice Sheet Divide to produce records going back some 2,000 years. Their analysis shown that recent melting in that area, which has caused a good deal of hysteria* in climate alarmist circles, is in fact normal.

“If we could look back at this region of Antarctica in the 1940s and 1830s, we would find that the regional climate would look a lot like it does today, and I think we also would find the glaciers retreating much as they are today,” comments Eric Steig, a senior earth-sciences boffin at the University of Washington and the lead author on the new research.

Ice loss in recent times from the Western Antarctic - considered to be one of the main places to worry about, if you worry about sea-level rises - may just "not be all that unusual", according to Steig.

The problem, as with many climate change issues, is that conditions in the Western Antarctic vary so much over short time scales that it's hard to work out if any long-term change is actually happening.

“The magnitude of unforced natural variability is very big in this area,” Steig comments.

Another major ice study recently came to similar conclusions regarding the likewise much-discussed Antarctic Peninsula: that recent melting there is not unprecedented, and indeed that various large bits of ice in that area - which today are still intact - probably broke off or melted at times in the pre-industrial past.

Stieg and his colleagues' paper is published in Nature Geoscience. ®

Oh look, the two dates they pick out correspond to two peaks in the upslope

Summer Ice Melt In Antarctica Is At The Highest Point In 1,000 Years, Researchers Say

CANBERRA (Reuters) - The summer ice melt in parts of Antarctica is at its highest level in 1,000 years, Australian and British researchers reported on Monday, adding new evidence of the impact of global warming on sensitive Antarctic glaciers and ice shelves.

Researchers from the Australian National University and the British Antarctic Survey found data taken from an ice core also shows the summer ice melt has been 10 times more intense over the past 50 years compared with 600 years ago.

"It's definitely evidence that the climate and the environment is changing in this part of Antarctica," lead researcher Nerilie Abram said.

Abram and her team drilled a 364-metre (400-yard) deep ice core on James Ross Island, near the northern tip of the Antarctic Peninsula, to measure historical temperatures and compare them with summer ice melt levels in the area.

They found that, while the temperatures have gradually increased by 1.6 degrees Celsius (2.9 degrees Fahrenheit) over 600 years, the rate of ice melting has been most intense over the past 50 years.

That shows the ice melt can increase dramatically in climate terms once temperatures hit a tipping point.

"Once your climate is at that level where it is starting to go above zero degrees, the amount of melt that will happen is very sensitive to any further increase in temperature you may have," Abram said.

Robert Mulvaney, from the British Antarctic Survey, said the stronger ice melts are likely responsible for faster glacier ice loss and some of the dramatic collapses from the Antarctic ice shelf over the past 50 years.

Their research was published in the Nature Geoscience journal.

No amount of evidence will satisfy the doubters because a model produced over 10 years ago was not able to predict exactly what the climate will do even though the actual variation were within the predicted tolerances of the models.

The politicising the debate by a couple of scientists who fudged a couple of numbers is no reason to throw the whole thing out.

10 (or what ever) years of trends not going up as steep as predicted but still within tolerances is no argument that the climate is not warming. The polar caps are one of many real evidence based, testable, observable, measureable indicators that the earth is warming.

We are stupid species collectively. Our long term survival chances are questionable. We need the Q to come and judge us now... not in a couple of hundred years time. Mankind... a fucking bunch of monkey's navel gazing as we destroy that .... that keeps us alive......

New ice core research suggests that, while the changes are dramatic, they cannot be attributed with confidence to human-caused global warming, said Eric Steig, a University of Washington professor of Earth and space sciences.

Prior to the year 2000, the GISS US temperature graph appeared as the flatter version. Note that 1998 was more than half a degree C (almost 1ºF) cooler than 1934.



In the year 2000, they switched places. 1998 became warmer than 1934. The difference you can see in the two graphs overlayed. How did this magic occur?
Most temperatures readings made prior to 1950 have been lowered ex post facto, and most years after 1950 have been raised successively higher. In fact, all temperature readings taken after 1990 have more than 0.5 degrees F added on to what was actually measured by the thermometers

Climate Science Confirms: The Unprecedented Medieval Warming vs. The Modern Warming
The anti-science Democrats and left-wing greens absolutely hate the Medieval Warming Period (MWP), due to its invalidation of the modern CO2 global warming-climate change hypothesis - no matter their extraordinarily lame corrupted/bogus attempts to prove otherwise, the objective empirical evidence continues to confirm the MWP was an uniquely extended warm era.

In another fascinating expose of climate science flim-flam produced by yet another group of academia climate-quacks, Steve McIntyre has the adjacent chart embedded in his article.

This chart represents a 5,000 year span of temperature variation in the Arctic region (Ellesmere Island) per peer-reviewed research . To add context, we superimposed the atmospheric CO2 levels (mauve curve) from the last 2,000 years.

Several very obvious conclusions can be drawn that gut claims by anti-science alarmists and quacks:

1. Climate change is a science-proven constant.

2. Periods of global warming and global cooling happen frequently

3. The Medieval and Roman periods were warmer than the modern era

4. Temperatures changed regardless of CO2 levels

5. CO2, be it natural or human, is not the globe's "thermostat"

Finally, per the HockeySchtick blog, it is known that the essentially barren Ellesmere Island had temperatures some 2 to 3 degrees higher than current temps, despite the gigantic CO2 emissions of our modern consumer/industrial era.
