It’s official. The scare is over. The World Federation of Scientists, at its annual seminars on planetary emergencies, has been advised by its own climate monitoring panel that global warming is no longer a planetary emergency.
The Earth’s climate .. is a dynamic and continually-changing system. “Human societies have lived and thriven under every conceivable climate, and modern technology makes adaptation to changing weather conditions entirely routine.”
The increasing fraction of CO2 in the air could be expected to result in some warming, but it had been accepted that “the benefits of food production and the relief of starvation overwhelm concerns about the potential climate changes induced by land-surface modification.” .. essential to ask whether similar reasoning applied to global fossil-energy production.
.. “Our greatest concern at present is that the intellectual climate for scientific investigation of these matters has become so hostile and politicized that the necessary research and debate cannot freely take place.
.. the panel found persuasive indications that climate models systematically understated natural climate variability and significantly exaggerated the impact of CO2 emissions. Accordingly, past, present and proposed policy measures could be shown not to provide net benefits to society regardless of the rate at which the planet might warm. Limited resources would be better devoted to more pressing issues.
