It's all over but for the sweating?

The tree ring data does coincide with the temperature data most of the time. And there are multiple proxies, and now multiple types of data. The science is clear - we are seeing unprecedented warming, and it is caused largely by us humans burning fossil fuels.

New paper pegs climate sensitivity at 1.6 DegC for every doubling of CO2

Which has been found quite a few times recently.

Policy in action (or inaction). EU ETS looks doomed.

EU climate policy in crisis after ETS rejection | European Voice

MEPs voted in Strasbourg today (16 April) to reject a proposal from the European Commission to delay auctioning of carbon allowances in the European Union's emissions trading scheme (ETS).

The carbon market fell by the highest rate ever following the vote, with the price of carbon plummeting by as much as 45% to a record low of €2.63. The proposal would have delayed the auctioning of some allowances in order to increase the deflated price of carbon, which was meant to be around €30 at this point. But heavy industry warned that this type of intervention in a market mechanism would erode confidence in the system.

The vote, with 334 MEPs against the proposal and 315 for it, is itself being seen as a crisis of confidence in the system. Stig Schjølset, head of EU carbon analysis for PointCarbon, said the proposal is now “effectively dead”.

“This means there will be no changes to the current system until 2020,” he said. “Prices will stay really low up to then. The EU ETS will not bring about any additional greenhouse gas reductions, so it will be irrelevant in terms of reducing total emissions in Europe.”

"The EU's carbon market is at crisis point,” said Green MEP Bas Eickhout after the vote. He called the combination of centre-right MEPs, German Liberals and some hard left MEPs from the GUE group who voted to reject the proposal an “irresponsible and unholy alliance of MEPs.”

Temperature is increasing because of increasing carbon dioxide (this time) and I have seen an estimate that we will inevitably see 1.5C even if we stopped all burning of fossil carbon fuels. But it won't be linear, because there will be feedback loops - and we do not know precisely what the various tipping points will be.

Here's so new information on the ice in Greenland:

I did not know that Greenland is an atoll, and there are at least 4 fjords that connect from the inner valley out to the ocean.

Could you define Atoll in this context ?

If you watch the video, they show a 3D map of the land under the ice.

Here are two reports on effects of climate change:

Scientists have been worried about coral reefs for years, since realizing that rising temperatures and rising ocean acidity are hard on organisms that build their skeletons from calcium carbonate. Researchers on Australia's Great Barrier Reef are conducting an experiment that demonstrates just how much corals could suffer in the coming decades.

State of the Climate | Global Analysis - March 2013

•The combined average temperature over global land and ocean surfaces for March 2013 tied with 2006 as the 10th warmest on record, at 0.58°C (1.04°F) above the 20th century average of 12.3°C (54.1°F).

•The global land surface temperature was 1.06°C (1.91°F) above the 20th century average of 5.0°C (40.8°F), the 11th warmest March on record. For the ocean, the March global sea surface temperature was 0.41°C (0.74°F) above the 20th century average of 15.9°C (60.7°F), making it the ninth warmest March on record.

•The combined global land and ocean average surface temperature for the January–March period (year-to-date) was 0.58°C (1.04°F) above the 20th century average of 12.3°C (54.1°F), the eighth warmest such period on record.

TSI approx. 1361.6w/m^2

For those keeping track for the year.... that's 9th, 9th, 10th.

It's not an atholl - it's like an atholl. Atholl i classical sens is build from coral. In greenland 1 km of ice depress the bedrocks in the middel, so you get af kind of bowl.

When ice melts this rock wil start to rise

I just listened to:

Freeman Dyson: Heretical Thoughts About Science and Society

He describes 6 heresies (and calls for more). The 2nd is CO2/Global Warning, the 3rd is (always one of my favorites) a wet Sahara 6K years ago, and the 6th—Rural Poverty, reminded me of Cool Planet.

[NeilBlanchard]

Do you mean wet Sahara 60,000 years ago? That is not all that crazy, because that is more or less what probably happened. But 6,000 years ago - I doubt it.

Is he saying that carbon dioxide is not a greenhouse gas?
