Can't it make up its mind?

Seems that global warming is doing different things depending on where you are: "The North and South poles are both subject to solar radiation and rising levels of climate-warming greenhouse gases, the researchers said. But Antarctica is also affected by an ozone hole hovering high above it during the austral summer. In the Arctic, Francis and co-authors of the research said, warming spurred by human-generated carbon dioxide emissions has combined with natural climate variations to create a "perfect Arctic storm" that caused a dramatic disappearance of sea ice last year, a trend likely to continue. In Antarctica, the ozone hole adds a new factor to an already complicated set of weather patterns, according to Gareth Marshall of the British Antarctic Survey. The changes in air pressure that go along with depleted stratospheric ozone are responsible for an increase in the westerly winds that whip around the Southern Ocean, at latitudes a bit north of most of Antarctica. These winds isolate much of the southern continent from some of the impact of global warming, Marshall said. The exception is the Antarctic Peninsula, which reaches northward toward South America. There, the effects of warming have been dramatic, he said, because the winds that protect the rest of Antarctica do not insulate the peninsula. The stratospheric ozone hole, caused by the ozone-depleting release of chemicals found in refrigerants and hair sprays, is likely to fully recover by 2070 as less of these chemicals are in use, as a result of international agreements. The ozone layer shields Earth from harmful solar radiation, but its recovery is likely to open the way for warming in central Antarctica, the scientists said."

There are other confusing studies being released, and two weeks ago, as North America emerged from its coldest and snowiest winter for decades, the US National Climate Data Center, run by the National Oceanic and Atmospheric Administration (NOAA) issued a statement that snow cover in January on the Eurasian land mass had been the most extensive ever recorded, and that in the US the month of March had been only the 63rd warmest since records began in 1895. On April 24 the World Wildife Fund (WWF), another body keen to keep the warmist flag flying, published a study warning that Arctic sea ice was melting so fast that it may soon reach a "tipping point" where "irreversible change" takes place. This was based on last September's data, showing ice cover having shrunk over six months from 13 million square kilometres to just 3 million. What the WWF omitted to mention was that by March the ice had recovered to 14 million sq km (see the website Cryosphere Today), and that ice-cover around the Bering Strait and Alaska that month was at its highest level ever recorded. (At the same time Antarctic sea ice-cover was also at its highest-ever level, 30 per cent above normal). The most dramatic evidence, however, emerged last week with an announcement by Nasa's Jet Propulsion Laboratory that an immense slow-cycling movement of water in the Pacific, known as the Pacific Decadal Oscillation (PDO), had unexpectedly shifted into its cool phase, something which only happens every 30 years or so, ultimately affecting climate all over the globe. Discussion of this on the invaluable Watts Up With That website, run by the US meteorologist Anthony Watts, shows how the alternations of the PDO between warm and cool coincided with each of the major temperature shifts of the 20th century - warming after 1905, cooling after 1946, warming again after 1977 - and how the new shift to a cool phase could have repercussions for decades to come.
