Trends in extreme weather events in Europe

Another big report on climate change, this from EASAC – the European Academies Science Advisory Council
In recent years, Europe has suffered a rising number of extreme weather events - from unprecedented heat waves and droughts to record-breaking floods, wind storms and freezes. These events do not respect borders and it is vital that Europe’s policy makers come together to devise common strategies to help mitigate the physical, human and economic costs. This new EASAC report based on a comprehensive collection of scientific data from the last 20 years provides just such a rallying call.

And on a similar theme, I've been watching the live webcast from across the pond where the National Academy of Science has been presenting its new report 'Abrupt Impacts of Climate Change: Anticipating Surprises'

The pdf of the report can be downloaded for free from http://nas-sites.org/americasclimatecho ... te-change/
but you have to login as a guest and tell them what you intend to do with the report. Well, it's a pdf so not much good for lighting fires or practicing origami. I told them I intended to read it.

Mind you, at 200 pages and 19Mb I might not read it all before tea time.

There's a four-page summary here: http://dels.nas.edu/resources/static-as ... AL-web.pdf

And to complete today's trio of major global warming publications we have from Jim Hansen:
http://www.columbia.edu/~jeh1/mailings/ ... osOneE.pdf

It comes with this covering letter:
The paper 'Assessing "Dangerous Climate Change": Required Reduction of Carbon Emissions to Protect Young People, Future Generations and Nature' is being published today in the leading open-access journal PLOS ONE. A 2-page paper summary + 4-page opinion (Hansen & Kharecha) re policy implications is available here or from my web site.

The paper was written to provide the scientific basis for legal actions against federal and state governments, in the United States and other nations, for not doing their job of protecting the rights of young people. The legal actions being filed by Our Children's Trust ask the courts to require the government to provide a plan for how they will reduce fossil fuel emissions consistent with stabilizing climate.

We dispute the common assumption that the world necessarily is going to develop all fossil fuels that can be found, thus making large global warming inevitable. Humanity does not need to be a bunch of lemmings headed over a cliff. Indeed, appropriate policies that phase out fossil fuel emissions over decades would be economically and environmentally beneficial. The editors of PLOS ONE, noting our statement "...there is still an opportunity for humanity to exercise free will", are establishing a "Responding to Climate Change" Collection in the journal PLOS ONE. They invite paper submissions in all areas of research and a broad range of disciplines aimed at returning Earth to a state of energy balance.

The paper draws attention to the moral and ethical issues caused by the inertia of the climate system, which causes most of the impacts of climate change to be felt by young people and future generations, as a consequence of action or inaction of the current generation. Besides this moral issue, we point out that effective government policies, collecting a rising carbon fee from the fossil fuel industry that made fossil fuels pay their costs to society, would be a path to economic prosperity, while business-as-usual only assures economic decline.

Jim Hansen is a hero.

Pretty much continuous windy weather but Christmas Eve gets particularly interesting with a forecast pressure of 936mb. That's close to the all time record.

That's perfect. It will mean an express return to Lapland for Santa.

It's just one thing after another but Monday will not be a good time for paddling in the sea on the south and west coasts.

The 'Significant wave height' is not a simple thing - see http://en.wikipedia.org/wiki/Significant_wave_height

but it means that one might expect, from time to time, a wave that is twice as high... or more

It's the unexpected one at the far right of the diagram that you don't want to be standing on the prom looking at when it comes along.

On Monday afternoon, a vast area of the NE Atlantic will be filled with waves that have an energy of over 25 million Joules per metre per wave.

Image

Now it's hard to get one's head round these sort of things. Perhaps this helps. One Joule is the energy released when a modestly sized apple falls from a table top to the floor. (Or, conversely, the amount of work it takes to lift the apple from floor to table top.)

So one has to imagine 25 million apples dropping on every metre of wave over an area almost the size of Europe.

Judging by recent news reports, it won't stop some people trying it.
