The problem is as real and as huge as climate science has been saying and yes, it's not hard to find wasteful and inappropriate projects and spending but these are almost entirely down to the failures of mainstream politics to face it head on with the seriousness it deserves. Instead of effective policy followed by real action they are giving us greenwash and they're hoping we'll buy it.
It's not those most most serious and most determined to deal with climate change that are responsible for that. I for one deplore the abuse and rorting of this very real issue by those who pretend to want action but actually want to line their own pockets.
Until the free market ideologies and politics find ways to adapt and produce solutions to this huge global challenge - instead of trying to disbelieve it away and blaming the loudest (often but not exclusively green) voices for climate, long term sustainability and the environment being an issue at all - ineffective and wasteful programs will almost certainly continue.
