President Obama's plan to cut greenhouse gas emissions may look like a climate victory, writes Tim Kruger – but it's no such thing. It's feeble because the US can meet its targets by reducing emissions to 2030 more slowly than it has since 2000. And it's fragile as any future President can scrap it at will.Climate change-denying Republicans hate this plan (of course), therefore all good climate realists see it as a triumph. But it is a tiny, tiny step in the right direction and climatically immaterial.No doubt, you heard the good news. Barack Obama has announced the US is pushing through plans to reduce emissions of greenhouse gases. Rejoice! Rejoice! We've got this climate problem licked – hurrah!
