Graphs and Charts on Climate Change

Below we have submitted graphs and charters on Climate Change.  These were taken from an excellent article in the Guardian,  The article was published to fill a demand for more information about Climate change.  In particular graphs and charts going how much change has occurred.
 Much has been written about climate change in recent months, what with that record-breaking hot year we just had and the qualified success of the Paris climate talks.


The forecast is for continued global warming largely driven by continued high levels of greenhouse gases.

MetOffice
Above is a chart from the UK’s MetOffice showing the three main global temperature data sets. These, for the hardcore among you, are known as HadCrut4 (MetOffice), GISTEMP (NASA) and MLOST (NOAA).

Pretty clear, right? All three show 2015 was the hottest year on record.

The chart shows “anomalies” (that’s the temperatures above or below a long-term average), in this case, against the average temperature between 1961 and 1990.

So for the MetOffice data, 2015 was 0.75C above the long-term average.

In December 2014, the MetOffice guessed (and when I say guess, I mean they used some powerful, skilful and sophisticated modelling) that 2015 would be between 0.52 and 0.76C above average. So they were right. Just.

And while we’re talking about forecasts from the MetOffice, here’s another one of theirs from a few days ago.

The MetOffice now makes “decadal” forecasts – that is, another of their guesses (same caveats apply as before with the term “guess”) on “near term” conditions globally over the next five years.

The black line shows actual temperature measurements. The red band are previous predictions and the green band shows the expected range according to climate models.

In short, according to the MetOffice, the forecast is “for continued global warming largely driven by continued high levels of greenhouse gases”.

You can’t really talk about global warming without talking about the oceans, given that this is where the vast majority of the extra heat and the extra carbon dioxide ends up.

The above chart, from the National Oceanic and Atmospheric Administration, shows the latest temperature readings from ships and from a network of almost 4,000 floats – known as the Argo array.

A study published a couple of weeks ago found heating of the oceans was accelerating, particularly in the deeper ocean.

No matter how you interpret this graphs they all have one thing in common temperatures are rising  Some nations are taking it more serious than others.
