    Rising carbon dioxide in the atmosphere has a "fertilization effect" on plants in arid regions that has contributed to the flourishing of foliage there, Australian researchers report.

    An upside to climate change? The issue has been blamed for many problems, including more acidic oceans and rising pollen counts, but a study released Friday suggests a benefit: Arid regions are getting greener.
    Satellite data since the early 1980s have shown a flourishing of foliage worldwide, and scientists have suspected this change may be due partly to the increase in atmospheric carbon dioxide, a heat-trapping greenhouse gas emitted by the burning of fossil fuels..
    Turns out, they were right because of CO2's "fertilization effect," according to a team of scientists led by Randall Donohue of the Commonwealth Scientific and Industrial Research Organization in Canberra, Australia.
    Their mathematical model predicted a foliage increase of 5% to 10%, based on the 14% hike in atmospheric CO2 from 1982 to 2010, for the regions they studied: the southwestern corner of North America, Australia's outback, the Middle East and some parts of Africa.
    What actually happened? Satellites showed an 11% increase in foliage after adjusting data for precipitation.
    Donohue said prior research linked the rise in global vegetation to "fairly obvious climatic variables" such as rising temperatures in normally cold places or rising rainfall in typically dry areas. He said his team is the first to show a CO2 link.
    "If elevated CO2 causes the water use of individual leaves to drop, plants will respond by increasing their total numbers of leaves," Donohue said in announcing the findings. The study has been accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union.
    Donohue said the "fertilization effect" could also alter the types of vegetation in dry areas. "Trees are re-invading grass lands, and this could quite possibly be related to the CO2 effect," he said.. "Long lived woody plants are deep rooted and are likely to benefit more than grasses from an increase in CO2."

    Unprecedented July Cold – Arctic Sees Shortest Summer On Record

    By Robert On August 2, 2013 · 66 Comments







    “Normally the high Arctic has about 90 days above freezing. This year there was less than half that,” says Steven Goddard website.

    Очевидно, одна (из многих) метрик в этом году окажется ниже. Нужно понять, как это влияет на общую картину климата. Не исключено, что никак.

    Default Глобальное потепление? Уже нет !!!!!!!

    на вышеприведенный текст гугл выдает ссылки на бесчисленные блоги, считающие это окончательным концом теории климатического заговора

    вместе с ними чуть было не обрадовался и я... уж очень хотелось верить, что деятельность человека по добыче энергии сжиганием фоссилов никоим образом не меняет климат на планете... а даже наоборот
    тем более что вновь открытые несметные залежи нефти и газа обещают небывалый рывок в прогрессе и сопутствующем ему отжиге углеводородов....

    единственно что немного настораживает:
    This year’s melt season has trended only a little below the 1981 – 2010 average up until about mid-june, then taken a dramatic downward turn. If it does not level off, ice loss will soon match the 2012 pace.
    .
    .
    .

    It’s not clear if 2013 levels will match 2012′s astonishing record low,
    but – with temperatures over the Arctic Ocean 1-3 degrees above
    average – the 2013 melt season has picked up in earnest during July.

    “During the first two weeks of July, ice extent declined at a rate of
    132,000 square kilometers (51,000 square miles) per day. This was
    61% faster than the average rate of decline over the period 1981
    to 2010 of 82,000 square kilometers (32,000 square miles) per day,
    ” the National Snow and Ice Data Center writes on its website.
    .......
    .
    .
    .

    Arctic shipping is set for a record year, underlining how melting sea ice is raising the prospect of an important new route for trade between Asia and Europe that shaves thousands of kilometres off the trip.

    As of Friday, the administrators of the Northern Sea Route (NSR) – which follows the north coast of Russia – had granted permission to 204 ships to sail this year. In 2012, only 46 ships sailed the entire length from Europe to Asia, up from four vessels just two years earlier.
    .
    .
    .

    ....... Commenter Danp opened a thread on the ASIF a couple of days ago,
    showing a cleaned up compilation he made of LANCE-MODIS satellite
    images (like commenter dabize did last year). The result looks very
    nice indeed, giving us a clear view of the holes on the Atlantic side
    of the Arctic, near the North Pole:
    Ice experts weigh in – but those swiss-cheese like holes near the pole appear to be signs that we could see a dramatic disintegration later in the summer.
    .
    .
    .
    но все равно хочется верить в лучшее - что с климат не теплеет и все будет хорошо

    Лучше бы закончили с исследованиями и на оставшиеся деньги начали разработку альтернативных источников энергии. Избавит ли это от потепления, не избавит - но воздух хоть будет чище

    поздно...
    нашли океаны нефти... сравнительно недорогой
    так что будет новый виток ее бездумного прожигания... о чистом воздухе и альтернативной энергии можно смело забыть лет так на сотенку

    Не, ну какие-то там ученые же на какие-то шиши проводят кучу разных исследований, чтобы доказать глобальное потепление? Вот лучше бы на эти шиши наняли ученых, которые бы занимались энергией
