Why is the world cooling.?

Alex,

The world isn’t cooling at all. There are some people who try to pretend that global warming isn’t happening and to this end they make up all sorts of nonsense. It appears the graph that you posted was created in August last year by an engineer (not a scientist) who runs his own website with the aim of spreading lies and propaganda about global warming. His name is Pierre Gosselin and his website is called No Tricks Zone.

Hopefully you’re not buying into the global cooling nonsense, if you are then I’d strongly suggest doing some research of your own and only relying on reputable sources.

The graph you posted is a feeble attempt at deception. It is nothing more than cherry picked data. 1998 was the year of the strongest El Nino ever recorded and this pushed temperatures unusually high. Doing any direct comparison with 1998 is a really dumb thing to do.

Using exactly the same data from exactly the same source, what happens if we bring the graph right up to date?

It shows warming.

What happens if we change the start year from 1998 to 1997?

That also shows warming.

How about changing it to 1999?

Once again it’s warming.

The only way to show cooling is to choose very specific start and end points. Someone would only do this if they didn’t have a clue what they were doing or, as appears to be the case here, they’re attempting to fool people.

So… what happens when we look honestly and rationally at global temperatures. Again, exactly the same source and data used in your graph but this time over the last 30 years, this being the minimum period of time for identifying a climatic trend:

Yet again it shows warming.

The reality is that global temperatures have levelled off in recent years. This has got nothing to do with global cooling, impending ice-ages or failed warming predictions. There are several contributory factors including decreased solar energy, emissions of cooling agents from China and India, increased heat flow into the oceans and perhaps most importantly, a very strong negative phase affecting the Pacific Ocean.

This negative phase is one half of something known as the Pacific Decadal Oscillation. When in it’s negative phase, as it has been for 16 years, the world should cool down. In fact, because of global warming there has been no cooling, temperatures have only levelled off.

When this oscillation switches back into positive phase there will be very pronounced warming, this will happen at some point within the next few years.

>>It is pretty funny to me that Gring0 thinks his time interval is more relevant than yours. It is all about selecting the time interval to make it say what you want.<<

You are both wrong. The issue is degrees of freedom – and since Gring0 has more data, his graph is better.

The asker's graph does not support cooling – because it is not valid scientific evidence - because the time period is too short to resolve the temperature signal.

If either of you scientifically- and mathematically-challenged nitwits can provide a scientific test suggesting that the earth is cooling – or that the trend has changed in any way since 1998 – then show it to us. Otherwise, quit pretending that you know anything about any of this.

The world heats up and cools down it has done since the beginning of time we had the mini Ice age and the medieval warm period which was before the pollution we have now it's all about making money.

Jim Z is correct. Gring0 is simply doing what alarmists have been doing since this whole issue became an issue. Most scientists understand that the Little Ice Age ended in the mid-19th century. Of course an alarmist's graph is going to show warming.

You also have to understand that these are "anomalies" and not actual temperature measurements of the Earth. Science can not pinpoint the "actual" temperature. It is impossible to measure at this point in time. Anomalies are used to identify trends and their accuracy is always being adjusted. If they were so sure of these measurements being an actual representation, they wouldn't be adjusting them continually.

that graph is difficult to read, but i think its the temperatures for december..?

anyway, global warming is not an accurate term. the correct term is climate change, because is causes hotter summers, colder winters, and generally more extreme weather, which causes a drop in temperature during the winter.

I can demonstrate, pretty easily, that your results are cherry-picking.

You started in '98 and ended in '13

For several date ranges:

Definite cooling:

none that I plotted

Very slight cooling:

'98-'12, '98-'13

Very slight warming:

'98-'11, '98-'10, '97-'13, '97-'12, '97-'10

Definite warming:

'99-'10, '99-'11, '99-'12, '99-'13, '97-'11, '96-'10, '96-'11, '96-'12, '96-'13

(the "slight" vs "definite" distinction was made kind of arbitrarily, but you can check the numbers for yourself)

I stopped at '13 because that's the last full year for which we have data.

Note how many year sets are in each category...

it's not. most of the planet is covered by oceans, yet you chose land surface temperatures. Nice trick to chose 1998 as your starting point.

Because of less solar activity. It's actually the Sun that drives climate and NOT human activity.

Watch these and allow some of the world's leading climate scientists to explain.

Top climate scientists say there is no man-made Global Warming.

It is pretty funny to me that Gring0 thinks his time interval is more relevant than yours. It is all about selecting the time interval to make it say what you want. Gring0 chose to start from the coldest point in recent history. If he chose a thousand year interval, it would likely be pretty flat IMO and if they chose 2000 it would probably show a slight cooling trend.
