American scientists revamp efforts to educate American public of ‘irreversible’ damage of climate change.

The UN climate science panel, the PCC, will gather in Japan next week to release the second in a series of important reports. This time outlining how changing climate is affecting rainfall and heat waves, sea levels and oceans, fisheries and food security.

The American Association for the Advancement of Scientists have issues a timely warning that: “We face risks of abrupt, unpredictable and potentially irreversible changes, and responding now will lower the risks and costs of taking action.”

In a rare intervention into a policy debate, AAAS urged Americans to act swiftly to reduce greenhouse gas emissions – and lower the risks of leaving a climate catastrophe for future generations.

There were concerens that Americans still failed to appreciate the seriousness of climate change, despite “overwhelming evidence”.

“The sooner we make a concerted effort ot curtail the burning of fossil fuels as our primary energy source and releasing the Co2 to the air, the lower our risk and cost will me.”
