Why We Need To Start Now

As if the previous news about Arctic ice wasn't enough, this shows why we need to start reducing CO2 now:

GENEVA (Reuters) - The hole in the ozone layer above Antarctica has grown to near record size this year, suggesting 20 years of pollution controls have so far had little effect, the United Nations said on Friday.

In a bulletin on the seasonal depletion of ozone gas, which filters harmful ultraviolet radiation that can cause skin cancer and cataracts, the U.N.'s World Meteorological Organization (WMO) said the hole would peak within a couple of weeks....

U.S. scientists reported last month that the ozone layer has stopped shrinking but it will take decades to start recovering....

Many CFCs, once commonly used in refrigeration, air conditioning and industrial cleaning, were banned by the Vienna Convention, signed exactly 20 years ago, and its Montreal Protocol clinched in 1987....

In a statement, U.N. Secretary-General Kofi Annan said that the 189 states to have ratified the Montreal Protocol had eliminated more than 1.5 million tonnes of annual production of chemicals that destroy the ozone layer.

But developing countries were "only at the half-way point in many of their obligations" under the pact, while in wealthy countries a number of chemicals still needed to be phased out.

Get it? We started banning CFCs shortly after I was born - with far less scientific consensus about the ozone layer than exists now about climate change - and we're still at it. We need to vastly surpass our Kyoto targets, and we need to start now.
