Global cooling continues

[trev]

Global cooling began in the Australian winter with the coldest and wettest winter for more than a decade, with spring being even colder and wetter compared to recent years. Now as I predicted in an earlier thread I it is spreading around the world with England experiencing the full effects of a cold wintry blast even before the real start of winter.
Of course this is the effects of the strongest La Nina for many years, but it bets the question, was the reason for global warming the presence of many El Ninos and lack of La Ninas in recent decades, because they do have a very real impact on the global climate. If La Ninas dominate over El Ninos for a decade or two as has happened in the past (these things are cyclical) will it reverse recent global warming for a decade or two at least.

No.

So a known influence on the global climate can be ignored with a simplistic 'No'.

[Egbert]

I can assure you that the answer to your question is a most resounding "yes". This is Poly OT.

Anyway, the world seems to be getting hotter and getting colder and staying the same all at the same time if I believe everything I read in the media.

I thought Australia was having a terrible drought? Or was that a while ago before it started raining?

[dannubis]

trev, global average temperatures have risen, even if some regions have experienced periods of "extreme" cold weather.

Your question was

will it reverse recent global warming for a decade or two at least

The answer to that is a simple 'No'. It won't reverse anything. Average global temperatures might be increasing, but this is why Global Warming isn't a great name... people keep thinking it means that where they live should get hotter every year.

Some places will have big winters, those might have been more or less severe due to La Nina if we hadn't changed the climate so much. Depending on where you are and lots of other conditions.

And the most important point is that "the strongest La Nina for several years" is probably itself a consequence of Climate Change. There is a growing consensus that Climate Change is driving the increased amplitude of Southern Oscillation (the La Nina Il Nino cycle). This probably isn't a good thing considering the increased intensity of floods and storms associated with Il Nino.

So rather than being an influence on the global climate I'd say that it's more accurate that La Nina is a known influence on temperatures and weather conditions that appears to be influenced by the global climate.

Anything that happens on the East Coast of Australia is often exaggerated to the extent that outsiders think it has happened to all of Australia. But around 15 years of below average rainfull on the East Coast has come to an end in the last 12 months with repeated floods since about December last year. The remainder of the country during that 15 years had less drought years, but none particularly wet years except on the tropical north coast where some years where quite wet. While the East is now saturated with flooding rains occuring today again in Victoria, the West Coast is experiencing a severe drought, quite often it gets the opposite of the East Coast.
The inflows into the Murray Darling river system have been so high this year, they have already replaced the deficit caused by 5 years or so of the drought and with more flooding rains occuring for the next few days, the flows will continue to increase.

How things change quickly when the facts change. Before the 2nd La Nina in 3 years and after a run of frequent El Ninos it was considered that climate change was the cause of frequent El Ninos and lack of La Ninas. Now suddenly it is driving an increased amplitude of these events, not causing more El Ninos. Considering that although this is the strongest La Nina in almost 2 decades, it is NOT outside the usual range of La Ninas and recent El Ninos have not been in general particularly strong, there does not seem to be any facts to support the new 'increasing amplitude' theory, but I suppose they had to replace the last theory of increasing El Nino events when that was no longer happening.

Gee, look how cold it's been!

Cold in Australia = cold everywhere. FACT!

Here's a year-to-date one:

[trev]

Those graphs are not surprising. The graph of 10 months reflects the warming of the El Nino from last year, The La Nina only commenced in month 7, so it shows 6 months of warmer climate from last years El Nino and 4 months of La Nina. It takes time for the La Nina effects to spread to the northern Hemisphere and the maps show that has begun, maps that show a June to June period will show the effects of La Nina and El Nino much more accurately.

Hmm, seems like a lot of warm years lately.


Not sure where you're getting this "global cooling continues" thing from.

[trev]

A look at your last graph shows warming peaked in about 2005 and the blue trend line has declined since and with the La Nina will continue to decline. So global cooling continues.

Once more demonstrating that all Austrians are clueless yet opinionated.
