Global Skies Turn A Pale Anemic Shade Of White?

[macdoc]

MM You think peak ice extent in dead winter has anything to say about Arctic ice -
Last time I checked it was dark in the Arctic in winer - shows once again you don't know how your planet works.
Why don't you read what reality is instead of your whacked denier blogs

What's new in 2011?

Persistent warming has caused dramatic changes in the Arctic Ocean and the ecosystem it supports.

Ocean changes include reduced sea ice and freshening of the upper ocean, and impacts such as increased biological productivity at the base of the food chain and loss of habit for walrus and polar bears.

Now you think you know better than this international group of scientists who prepare this report each year and which I'm quite sure you have never read once despite it being available yearly since 2006,

The material presented in this Report Card was prepared by an international team of 121 scientists from 14 different countries, assisted by section coordinators and the editorial team. The Circumpolar Biodiversity Monitoring Program (CBMP) of the Arctic Council Conservation of Arctic Flora and Fauna (CAFF) Working Group contributed material on biodiversity. Independent peer-review of the 2011 Report Card was organized by the Arctic Monitoring and Assessment Programme of the Arctic Council.

You conflate atmospheric temperature with AGW - atmospheric is transient and you nicely pick the hottest year of the 90s as a start point which was a El Nino year which likely means nothing to you.
We've seen all the bullshit before from the deniers. All of sudden you think physics has been suspended despite the last decade being the hottest on record.
you are into giggle territory now denying the obvious - remarkable for tenacity to put it politely.

NOAA: Past Decade Warmest on Record According to Scientists in 48 Countries
Earth has been growing warmer for more than fifty years

The 2009 State of the Climate report released today draws on data for 10 key climate indicators that all point to the same finding: the scientific evidence that our world is warming is unmistakable. More than 300 scientists from 160 research groups in 48 countries contributed to the report, which confirms that the past decade was the warmest on record and that the Earth has been growing warmer over the last 50 years.

Now back to the topic after the comedy break courtesy AGW Denier Inc ( aka Koch and Exxon Watt et al )

Climatologists predicted global temperatures would drop as a result of that global sulfate infusion. They were right: Following the eruption, global temperatures abruptly dipped by about a half-degree (0.6°C) for about two years. And Pinatubo isn’t a unique event. Large, temperature-altering eruptions occur about once per decade.

Graphs of aerosols and temperature from 1850 through 2000.


Large volcanic eruptions may lift sulfate aerosols into the stratosphere, which usually cools the global climate for the following year or two. (Graph by Robert Simmon, based on aerosol data from GISS and temperature data from the UAE CRU.)

In addition to scattering or absorbing radiation, aerosols can alter the reflectivity, or albedo, of the planet. Bright surfaces reflect radiation and cool the climate, whereas darker surfaces absorb radiation and produce a warming effect. White sheets of sea ice, for example, reflect a great deal of radiation, whereas darker surfaces, such as the ocean, tend to absorb solar radiation and have a net warming effect.

Aerosols, particularly black carbon, can alter reflectivity by depositing a layer of dark residue on ice and other bright surfaces. In the Arctic especially, aerosols from wildfires and industrial pollution are likely hastening the melting of ice.

This is why the idea of Geo-engineering with S02 is a known if risky solution as any industrial nation has the ability alone to undertake it.
Other ideas like microbubbles and wind ships to reflect are far safer and controllable with little impact on the atmospheric chemistry

I never mentioned winter levels of ice. That's all in your head. I just pointed to the graph that you yourself posted.

I said that ice levels were rising and temperatures trends had not been rising for ten years. Make that fifteen. These are facts.

You like to include the hotter years, when pointing to warming, but don't like them, when they indicate no further warming has happened in 15 years. How consistent.

The recent increase in Arctic ice and level temperatures are no more significant than the bit of warming that went before. These things are always on the change. That's the point.


You quoted this:

Aerosols, particularly black carbon, can alter reflectivity by depositing a layer of dark residue on ice and other bright surfaces. In the Arctic especially, aerosols from wildfires and industrial pollution are likely hastening the melting of ice.

This is of course true, and it seems very likely that a significant proportion of melting of ice is down to soot particles, which darken the surface of the ice, and absorb solar energy.
Note the marked difference between the Antarctic, which is soot free, and has no overall melting, and the Arctic, which experiences a lot of pollution and fallout of soot particles.

where pray tell do you see an increase in Arctic sea ice.

Perhaps this will clarify your misapprehension.



as for the Antarctic ....you do understand that is not sea ice that is melting there but rather glaciers....

Perhaps we can improve your woeful understanding of the planet you dwell on

Antarctica Melting?01.12.10

The continent of Antarctica has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002.



There has been lots of talk lately about Antarctica and whether or not the continent's giant ice sheet is melting. One new paper 1, which states there’s less surface melting recently than in past years, has been cited as "proof" that there’s no global warming. Other evidence that the amount of sea ice around Antarctica seems to be increasing slightly 2-4 is being used in the same way. But both of these data points are misleading. Gravity data collected from space using NASA's Grace satellite show that Antarctica has been losing more than a hundred cubic kilometers (24 cubic miles) of ice each year since 2002. The latest data reveal that Antarctica is losing ice at an accelerating rate, too. How is it possible for surface melting to decrease, but for the continent to lose mass anyway? The answer boils down to the fact that ice can flow without melting.

The Antarctic ice sheet. East Antarctica is much higher in elevation than West Antarctica.

Two-thirds of Antarctica is a high, cold desert. Known as East Antarctica, this section has an average altitude of about 2 kilometer (1.2 miles), higher than the American Colorado Plateau. There is a continent about the size of Australia underneath all this ice; the ice sheet sitting on top averages at a little over 2 kilometer (1.2 miles) thick. If all of this ice melted, it would raise global sea level by about 60 meter (197 feet). But little, if any, surface warming is occurring over East Antarctica. Radar and laser-based satellite data show a little mass loss at the edges of East Antarctica, which is being partly offset by accumulation of snow in the interior, although a very recent result from the NASA/German Aerospace Center's Gravity Recovery and Climate Experiment (Grace) suggests that since 2006 there has been more ice loss from East Antarctica than previously thought 5. Overall, not much is going on in East Antarctica -- yet.

Now you do understand that the ozone depletion is also manmade???

Ozone hole 'protecting Antarctica' from global warning
BY: LEIGH DAYTON, SCIENCE WRITER From: The Australian December 02, 2009 12:04PM

THE ozone hole may be boosting the risk of skin cancer, but it's also protecting Antarctica from global warming, international researchers claim in an assessment of Antarctic climate change from the geological past to the present.

But as the ozone layer gradually heals - through a global protocol to cut the use of ozone-depleting compounds - the continent will warm rapidly, scientists claim in the Antarctic Climate Change and the Environment report, released yesterday by the Scientific Committee on Antarctic Research.

"Removal of the cooling effect of the ozone hole as it diminishes in extent will exacerbate the problem (of warming)," the report says.

CSIRO climate modelling expert Wenju Cai went further: "Even if ozone does not recover greenhouse gasses will overtake the cooling effect of ozone in the upper atmosphere".

There is no arguing with this record...



indeed solar dimming is shown keeping the temperature flat from the massive S02 in the atmosphere from the 40s to the 80s.

Notice the inverse between sulphate and temperature



Global dimming caused by sulphate release was in effect geo-engineering the climate during that period and offsetting the impact of rising C02 levels.
Clean up the sulphate and the temperature climbs.

So the "proposal" in the OP is to go to that solution. Not a good one in the opinion of many.

Course there si some few that grasp at straws that C02 is no threat anyway.....fools the lot.
