I'd like to apologize to bbr. I wish I wasn't so harsh this morning.

As posted elsewhere, this study firmly debunks Dr. Tskoul's baseless attacks on the NOAA datasets and confirms that precipitation is indeed increasing in Greece (and the Med in general).

If you refer to that coarse map at the top of the article, I would say that Greece is right between the more and less precipitation categories.

And from the local ground: I guess they don't know how to measure rain...

Quote
There is a worrying increase in all indicators that record the risk of desertification in the Eastern Mediterranean and in Greece, says academic Christos Zerefos, underlining the great importance of the problem on the eve of World War II and World War Day. Indeed, giving "news", Mr. Zerefos reveals to K that climate models to reduce rainfall in eastern Greece are already being modified for the worse: climate change, predicted, in the worst-case scenario, to reduce rainfall in the eastern regions of our country by 15%. The revision of estimates, which will be announced in the coming months, provides for a 20% reduction, ”Mr Zerefos told K. "Already in the last 100 years, there has been a 20% reduction in rainfalls in Western Greece, which is the region with the highest rainfall and the largest water reserves. In the east the decline is smaller, but the worst is coming, ”says the academic, based on the report of the Committee on Climate Change Study (EMEKA), set up by the Bank of Greece.

Why the injection of water in the Hansen paper happens at -15oC ??

Quote
Ice sheet discharge (icebergs plus meltwater) is mixed as freshwater with mean temperature −15◦C into the top three ocean layers (Fig. S6).

I would think fresh melt water is 0oC and melted sea ice is -1.8oC...

because some of it is ice

Ice would be at surface....not injected at 3 ocean layers

You are overcomplicating it, its a simply an energy balance. Hansen doesn't want to deal with iceberg armadas in the model, so he mixes the water in at an appropriate temperature to maintain the energy balance.
