The evidence keeps piling on
that the global temperatures are rising, despite the cheap stunts
of some nay-sayers with an agenda. Whether it is a cyclical climatic event or is man-made, is still a big argument, but the reality of climate change is getting supported by increasing amounts of data. But that is not what I am going to discuss here. The question is: So what to do? All efforts for limiting the CO2 emissions have failed so far. And scientists have started coming up with all sorts of ideas for using technology to prevent the thermal collapse of the planet. For some this sounds like the only possible way averting the devastating consequences of the runaway greenhouse effect (I am far from the thought that a Venus scenario
would occur, but still the damages on ecosystems and industries could be bigger than anticipated). For many others the very notion of tampering with the complex ecological systems of Earth is causing serious concerns that things could go terribly wrong.
When someone incidentally swallows a fly, should they also swallow a spider to amend the mistake? Since we continue emitting vast amounts of CO2 into the atmosphere, is it appropriate to try cooling Earth with risky technological methods? And, since Plan A (curbing the CO2 emissions) could fail, do we need a Plan B (geo-engineering)? Or like some call it, "climate engineering". Most people call this insane, megalomaniac, unacceptable when they hear it for the first time. And really, some of these hi-tech ideas sound very insane... not to mention how expensive they are. Flexible pipes rising 30 km into the sky on stratospheric balloons (or Zeppelins), where liquid SO2 would be sprinkled into the atmosphere and be spread across like an umbrella; stretching a shadowy umbrella consisting of millions of tiny mirrors floating in orbit; pouring vast amounts of iron salts into the ocean to stimulate the blossoming of the plankton and encourage it to absorb the CO2... And many more ideas.
As strange as they sound, we might have to toss them around soon, because geo-engineering is no longer a taboo subject. Many scientists in the West are already seriously dealing with these ideas. All the failed climate summits
in the recent years, the piling evidence for an accelerated warming of the atmosphere and the oceans, and the realisation that even if we stopped the CO2 emissions today the temperatures would still keep rising... all of that is prompting some voices to give radical proposals.( Collapse )
