The world now accepts that protecting our atmosphere, hydrosphere, lithosphere, biosphere and even cyberspace — the "global commons" — is the responsibility of all countries. Enforcing that norm is proving the difficult part.
And nowhere is the difficulty greater than in two areas: shielding our atmosphere from the buildup of global-warming greenhouse gases; and preventing cybercrime.
Of these two challenges, combating climate change is proving most difficult to crack. The reason for that is not hard to seek: effectively combating climate change demands fundamental shifts in national policies and approaches, as well as lifestyle changes in the developed world. It is easier to visualize than to actually devise carbon standards that can protect the material and social benefits of continued economic growth in the developing world and also help shield prosperity in the developed countries.
