Global Warming Has Not Stopped

One of the most common false arguments climate change deniers make is that global warming has stopped. This is remarkable for a number of reason, the first being that it is simply not true. But, I also find it amazing how the deniers keep pulling this out, no matter how many times they are shot down. So, let’s review this claim to see just how much validity there is to it.

First, let’s be clear of what is going on. Deniers point at a plot of data such as the one below and say, ‘Ah ha! There has been no warming since 1998. If we draw a line from there to today it is a flat line!’ See for yourself.

 

This is what is known as cherry picking, selecting the data to get the desired result. The problem is, why pick 1998? If we pick 1999, the next point on the graph, we get a tremendously different result. The line starting at the 1998 data point is pretty flat. The line starting at the 1999 data point increases quite a bit. The fact is, both would be cherry picking and both would be false arguments. That is why scientists use averages and long-term trends. We are not trying to obtain some predetermined result – that is what the deniers do, not scientists. We are trying to find out what is going on.

But, even if we cherry pick the starting point the denier claims are not true. Look at this plot of data from NASA/GISS:

Clearly, the warming has slowed down in recent years, but is continuing. In fact, nine of the ten hottest years ever recorded, and the three hottest, have occurred since the year 2000. Those figures alone give the lie to the claims of the deniers. But, there is much more.

The biggest lie in their claim is that they have been using the data above as ‘global’ warming. But, that data is only the surface temperature, basically the temperature of the air and land. When we say ‘global’ warming, though, we mean just that – the entire globe. What the deniers don’t want anyone to think about is the oceans. If you want to know about ‘global’ warming, take a look at this plot that shows how much heat is being stored and where its being stored:

The amount of energy being stored in the oceans is many times greater than what is being stored in the air and land. And, the amount of energy stored in the oceans has continued to rise. How is it possible for any person to look at this data and still insist global warming has stopped? I repeat my oft-made claim – the only way someone can deny global warming is to deny science. Deniers prove the validity of that claim every time they say global warming has stopped.

Now, they are in for even more trouble on this point. The temperature in April was tied for the hottest April ever. And now, we are told May was the single hottest May ever recorded.

And, the news keeps getting worse – worse for all of us, unfortunately. El Nino is setting in and there is a 70% chance of one occurring this summer and an 80% chance of one this fall. If it happens, then 2014 will continue to see warming temperature averages and 2015 could be even worse.

What do you think the deniers will say to cover their rear-ends when even the average person on the street will be able to see the deniers have been lying all along?

  1. It is evident. In the first place are money and economy and they do not care about our health of planet. They think now it is good for economy, if they do nothing about it, but this very bad for future and for their money and for every person on this planet, cos we are living here on the planet Earth and we love this planet and we want this planet healthy for good living and for the future for our generation. What we can do? We have got scientific proof, we can public how dangerous it is for planet and for us, but how to convince superpower? One day money will be no matter, because on unhealthy planet will not be life, even money and economy will be nothing and than you can buy fly on another planet.

  2. People make decisions based on the here and now. Deniers have done a good job of convincing people that climate change isn't something they need to worry about because it isn't affecting people right now. We need to convince people that this is something that is affecting their quality of life right now and they need to make decisions with that knowledge in mind.
