Predictions revisited and Climate Change: News and Comments

Guided hurricanes

When speculating four decades ago about the military uses of geophysics, Gordon J.F. MacDonald of UCLA contemplated the triggering of earthquakes or tsunamis, or melting polar ice with nuclear weapons. And he didn’t overlook the idea of steering hurricanes to ravage the enemy’s coasts. Reminding me of that prediction is a report now in press in Geophysical Research Letters, about how natural variations in the colour of the sea help to guide cyclones in the Pacific. A cyclone, remember, is a loosely used generic term that includes the major storms called hurricanes (Atlantic), typhoons (Pacific) or tropical cyclones (Indian Ocean and Australia).

Contributing to Unless Peace Comes, (1968), in a chapter entitled “How to Wreck the Environment”, MacDonald wrote:

… preliminary experiments have been carried out on the seeding of hurricanes. The dynamics of hurricanes and the mechanism by which energy is transferred from the ocean into the atmosphere supporting the hurricane are poorly understood. Yet various schemes for both dissipation and steering can be imagined. Although hurricanes originate in tropical regions, they can travel into temperate latitudes, as the residents of New England know only too well. A controlled hurricane could be used as a weapon to terrorize opponents over substantial parts of the populated world.

Monsoon 2010

Climate change: News and Comments

Floods in Pakistan, Relief in India

Harrowing news of lives lost in unusual monsoon floods in NW Pakistan, close to the Afghan border, doesn’t mean that this year’s rains have been exceptional across the subcontinent. On the contrary, the Indians were worried by a shortfall in early July.Their rains have now perked up.

Strong La Niña conditions (the opposite of El Niño) now showing in the Pacific are historically favourable for the Asian monsoon, and the India Meteorological Department seems to be sticking to an earlier forecast that this season’s total rains will be close to normal. See this Reuters interview with D. Sivananda Pai, director of the National Climate Center in Pune. http://in.reuters.com/article/idINSGE66K0IL20100721?loomia_ow=t0:s0:a54:g12:r3:c0.638402:b36099434:z3

Silly season for melting ice

The Silly Season Again for Melting Ice

At this time of year, while the Arctic sea ice dwindles under the midnight sun and the wind pushes it around, silly stories are needed to fill the pages of summer newspapers. So it’s party time for the global warming alarmists and their editorial cronies. For example, Nature magazine today laments:

Arctic melting: The Arctic has set another record for losing sea ice. Last month saw the lowest extent of sea ice in the Arctic for any June since satellite records started in 1979.”

[Note added 25 July: The day after I posted this, CNSNews reported Sen. John Kerry (D-Mass.) as saying,  “Instead of waiting until 2030 or whenever it was to have an ice-free Arctic, we’re going to have one in five or 10 years.”]

It’s a replay of the polar stories of 2007, mentioned in a 2008 talk on the Tradecraft of Propaganda that I posted earlier: https://calderup.wordpress.com/2010/06/07/tradecraft-of-propaganda/

Here’s the relevant extract from that talk: Last year [2007] you were told – shock, horror! — that Arctic sea ice was at its lowest extent since satellite measurements began. How that news was trumpeted on television and radio and in all the newspapers! What went completely unreported was that simultaneously, at the other end of the world, Antarctic sea ice was at a record high. Although the big freeze in Antarctica was again plainly announced in a press release from the US weather bureau, NOAA, not a single newspaper in North America or Europe carried this news unfavourable to the global warming brigade.

Let’s check what’s going on this year, around the southern end of the Earth’s axis.
