It’s global warming, it’s climate change, it’s our fault, no it’s volcanoes… wait, actually it’s the sun! Or maybe not.
The arguments about climate change have been raging for years. Some say that the warming is a natural occurrence, some blame humanity and then others simply say ‘what warming?’ One idea now at least can be put to rest – the sun is not to blame.
It has been very popular to cite that the planet goes through many warming and cooling periods as a direct result of changes in solar activity. It sounds fair enough, if the sun produces more heat we get warmer. And this was very much the idea put forward by Britain’s Channel 4 in their documentary called ‘The great global warming swindle.’ There is one main problem with blaming the sun – it’s just not true.
It is true that up until about 1980 all the information showed that solar activity was increasing. This is exactly what they showed on all of their graphs, and it looks both convincing and logical. The sun was outputting more energy, the planet was getting warmer, bingo, we have our culprit! But this is just not the case, the trend in solar activity changed.
“This paper is the final nail in the coffin for people who would like to make the sun responsible for present global warming,” Stefan Rahmstorf, a climate scientist at the Potsdam Institute for Climate Impact Research in Germany, told the journal Nature.
Mike Lockwood, from Oxford’s Rutherford-Appleton Laboratory and Claus Fröhlich, from the World Radiation Centre in Switzerland recently published their paper in the UK’s Royal Society’s journal, stating clear evidence that the warming of the past two decades is not due to the sun – we need to look elsewhere.
Not only does the sun fail to explain any rise in temperature but it would actually suggest a cooling, as clearly stated in the abstract of the paper, “There is considerable evidence for solar influence on the Earth’s pre-industrial climate and the Sun may well have been a factor in post-industrial climate change in the first half of the last century. Here we show that over the past 20 years, all the trends in the Sun that could have had an influence on the Earth’s climate have been in the opposite direction to that required to explain the observed rise in global mean temperatures.”
This study has compiled data about solar activity spanning the last one hundred years and have shown that solar activity peaked between 1985 and 1987.
“This is an important contribution to the scientific debate on climate change. At present there is a small minority which is seeking to deliberately confuse the public on the causes of climate change. They are often misrepresenting the science, when the reality is that the evidence is getting stronger every day. We have reached a point where a failure to take action to reduce carbon dioxide and other greenhouse gas emissions would be irresponsible and dangerous,” said a representative of the Royal Society.
Even though one theory countering global warming has been overturned new ones will come up every day. People will continue to say that the whole idea of climate change is nothing but government propaganda and a dozen or so other conspiracy theories. Now more than ever it is important for the public to be properly educated about what is going on. There are far too many places citing ‘scientific’ reasons as to why global warming is nothing but a lie. And sadly, with the way the media and the internet works, this is unlikely to change. Let’s just hope the politicians listen to the scientists and not to members of the public who are being confused and misled by far too many sources.
