Global warming missing in South America

September 1, 2013

It’s only weather of course but the current winter in South America affords no evidence of global warming. The heat – if it is there – is extremely well hidden.

  1. It is cold that is far more deadly than warmth;
  2. it is only the availability of affordable energy which can help us ward off the cold;
  3. And it is only conventional energy sources (fossil, nuclear and hydro) whic are both available and affordable

Peru snow state of emergency extended to more regions

The Peruvian government has extended to nine more regions a state of emergency called to cope with unusually cold weather and heavy snowfall. At least two people have died and 33,000 others have been affected by the cold spell, local officials say.

Tens of thousands of animals have frozen to death over the past week. President Ollanta Humala has travelled to Apurimac, one of the worst-hit areas, to oversee the distribution of emergency aid.

The state of emergency would be in place for 20 days, an official statement said. 

The heaviest snow fall to hit Peru in a decade has killed tens of thousands of llamas, alpacas, cattle and sheep, and left farmers destitute. A man died when the roof of his hut caved in under the weight of the snow in southern Carabaya province but the circumstances of the second death were unclear. Three people were rescued on Saturday from the same region after their home was cut off by snow. Rescue workers said the three, two girls and an elderly woman, were suffering from frostbite and snow blindness.

The cold front has also hit Peru’s south-eastern neighbour, Bolivia, and Paraguay, where a combined total of five people have died.

Solar effects on climate – evidence mounts that the Little Ice Age was a global event

May 9, 2012

And another paper showing that the Little Ice Age was a global event.It is highly probable that the LIA was related to the solar effects which gave a dearth of sunspots during the Maunder Minimum.

La Niña driving severe rains and floods in Brazil and Australia

January 12, 2011

The La Niña event established this year is particularly intense and maybe the most severe in a 100 years. Such events are known to give warm sea surface temperatures and greater evaporation giving heavy rains in the Western Pacific in Australia, less rain in the Eastern Pacific on the western coast of S. America (coastal Chile and Peru) but increased rain on the east coast in southern Brazil and  northern Argentina.

Yesterday, heavy rainfall and floods in Brazil  claimed 80 lives.

UPDATE!! This morning the death toll is reported to be over 250.

UPDATE 2!! 13th January: Now death toll is around 400.

BBC:

More than 80 people have died in towns near Rio de Janeiro as heavy rains continue to cause flooding and mudslides in south-eastern Brazil. Overnight downpours triggered landslides in the mountain town of Teresopolis, where more than 50 were reported to have died. At least three firefighters were among several people buried in mudslides in Nova Friburgo.

Brazil has seen severe flooding this year which has left thousands homeless.

The death toll is expected to climb as rescuers reach remote villages in the mountains. One report, compiling official and media figures, put the toll so far at 93.

This week, torrential rains in neighbouring Sao Paulo state left 13 people dead and brought traffic chaos to Brazil’s biggest city. In Teresopolis, 100km (62 miles) north of Rio Janeiro, a river burst its banks, submerging buildings, while the rainfall set off several mudslides.

The rains and floods in Queensland have claimed 13 lives so far but the peak in Brisbane a few hours ago was fortunately about 1 m lower than in the 1974 floods. Nevertheless many thousands of homes have been inundated and the damage to Queensland industry and agriculture is severe. The final death toll is likely to be higher since it is feared that some bodies will only be discovered after the waters recede. Now heavy rain and flash floods have hit Victoria as well.

The Guardian:

The devastating flooding in Queensland is the result of Australia being in the grip of an unusually strong “La Niña”, a periodic climate phenomenon that brings more rain to the western Pacific, and less to South America along the eastern Pacific.

“The Queensland floods are caused by what is one of the strongest – if not the strongest – La Niña events since our records began in the late 19th century,” said Prof Neville Nicholls at Monash University and president of the Australian Meteorological and Oceanographic Society. “The La Niña is associated with record warm sea-surface temperatures around Australia and these would have contributed to the heavy rains.” Warmer oceans produce damper air and hence more rain. This is driven onshore by the stronger east-to-west trade winds characteristic of La Niña.

In both Australia and S. America the rains have about another 2 months to run.

Antarctic sea ice extent almost 3 SD’s higher than “average”

November 25, 2010

The Southern Hemisphere is coming into summer but seems significantly cooler (and wetter in Australia) than usual.

The ice extent in the Antarctic is reducing much slower than normally and currently the sea ice extent is about 1.3 million sq. km or 9%  or 3 Standard Deviations higher than the 1979 – 2000 average.

The Pacific Oscillation – or La Nina – is probably responsible.

Summer delayed in the Southern Hemisphere?

October 15, 2010

The Northern Hemisphre is anticipating a long cold winter which might even be a little early, but summer is a little late in the Southern Hemisphere.

Usually Antacrtic ice starts decreasing around 15th September but this year it seems to be still quite high and delayed by about a month.

Meanwhile in Australia,

WARM weather may have teased the state into believing summer was on its way, but the wild weather predicted for the weekend could be winter’s last hurrah.

Meteorologists are warning of a wet and windy weekend with widespread rain, potential flash-flooding, and wind gusts of up to 110km/h. Snow is likely to fall on the alps and southern ranges, and even Orange could get a light dusting. The shift is being caused by a broad trough moving over NSW, which is expected to deepen into a low pressure system today, causing heavy rain and strong winds across central NSW.
