More droughts and flooding predicted as La Niña weather pattern goes into third consecutive winter

A media campaign to point the finger at the ‘greed of rich countries’ for local weather conditions is already underway in Pakistan. But NASA gave the game away after the last time this happened, in 2010: ‘The rainfall anomaly map published by NASA showed unusually intense monsoon rains attributed to La Niña’ – Wikipedia. Of course it’s now standard practice to try to blame humans in the more industrialised countries for any seriously bad weather.

More droughts and flooding are being predicted as the La Nina weather pattern goes into its third consecutive winter – something known as a “triple dip”, says Sky News.

The UN’s World Meteorological Organisation (WMO) predicts it will last until at least the end of the year.

That means it will have spanned three consecutive northern winters for the first time this century.

La Nina is the cooling of ocean surface temperatures coupled with winds and rainfall.

It tends to have the opposite effect to El Nino, which is the warm phase of the so-called El Nino Southern Oscillation.

It was in the last six weeks that La Nina conditions strengthened in the tropical Pacific, affecting temperatures and rain patterns and making drought and flooding worse in different parts of the world.

According to the WMO’s El Nino/La Nina Update, the current La Nina – which began in September 2020 – is likely to continue over the next six months.

There is a 70% chance of that happening between September and November, and a 55% chance between December and February.

“It is exceptional to have three consecutive years with a La Nina event,” said WMO Secretary-General Petteri Taalas.

“Its cooling influence is temporarily slowing the rise in global temperatures – but it will not halt or reverse the long-term warming trend.”

    This article by The Conversation makes the usual IPCC-type assumptions, but may still be worth a look.

    Pakistan floods: What role did climate change play?

    ‘Unusual monsoon rains over Pakistan have some predictability. They occur when multiple phenomena coincide, including a La Niña event in the Pacific and large meanders in the high-altitude jet stream, as was the case in both 2010 and this year.’

    Who here remembers being told by the cagw acolytes that our CO2 emissions would mean us entering a permanent El Niño ?

  6. La Nina is the cooling of ocean surface temperatures coupled with winds and rainfall.

    Sounds like that cooling of ocean surface and dropping huge amounts of rain or snow with the necessary IR out from the turning of water vapor into water and ice is more massive cooling of the climate system.
