Comfortably numb is no good
Most of those that deny the nature of reality are not doing so because they are being paid to do it (or even because they are willfully blind); they have just been duped by the Merchants of Doubt that say:
“Anthropogenic CO2 is not the cause of the climate change we are now witnessing; and
anyone who says otherwise is just trying to restrict your freedom and/or spoil your fun!”
It really is that simple. However, the hallucinatory drugs we have been taking will not work much longer. It is time to wake up and deal with the uncomfortable, numbing, reality that our stupidity has now begun to irreversibly change the Earth’s climate. Therefore the only question left to answer is:
Just how bad does it have to get before we all start trying to do something about it?
So then, how can we know for certain that CO2 is the main cause of the problem? Well, try this graph :
The graph above (available on the Wikipedia website) demonstrates that cyclical solar activity (variation in total solar irradiance (TSI), sunspots or anything else) cannot explain ongoing warming of the last 150 years. However, as Patrice Ayme pointed out in 2009, it does explain why the warming that has occurred – and is occurring – has not been consistent (also due to the cooling effects of other industrial pollutants, volcanic eruptions, etc.). In other words, global warming did not stop in 1998 (etc).
So will people now please stop saying things that are not true?
TSI may be more than 1 kW per square metre (which is an awful lot of energy but, be fair, the Earth has grown accustomed to being bombarded by it). However, what the Earth is struggling to cope with is the comparatively recent and sudden reduction in outgoing long-wave radiation caused by atmospheric CO2. This change may be small by comparison with TSI but it is still an order of magnitude greater than the change that brought the Earth out of the last Ice Age. This is why the Earth is warming up faster than it did then. Furthermore, now that the melting of terrestrial ice is accelerating; sea level rise will now do the same.
The longer we ignore what is happening the harder it will be to stop, mitigate and/or adapt.
Unfortunately, we cannot press CTRL+ALT+DEL to re-boot the system. Therefore, perhaps it is time we visited the Control Panel / Task Manager to stop the process that is in danger of crashing the computer?
