BBC Allow Dissent?

Coming off the heels of the Major New Complaint Submitted To BBC Over Climate Bias (Piers Corbyn is one of the signatories) I nearly choked reading the views of ‘climate heretics’ Lewis and Curry… on the BBC!

A co-author Prof Pierre Friedlingstein, from Exeter University, UK, told BBC News that carbon uptake from plants was factored into Intergovernmental Panel on Climate Change (IPCC) models, but was one of the main sources of uncertainty in future climate forecasts.

Warming the Earth releases CO2 by increasing decomposition of soil organic matter, thawing of permafrost, drying of soils, and reduced photosynthesis – potentially leading to tropical vegetation dieback.

He said: “Carbon sinks (such as forests, where carbon is stored) would become sources if carbon loss from warming becomes larger than carbon gain from fertilisation.

“But we can’t be certain yet when that would happen. Hopefully, the world will follow the Paris agreement objectives and limit warming below 2C.”

Nic Lewis, an independent scientist often critical of the IPCC, told BBC News: “The magnitude of the increase in vegetation appears to be considerably larger than suggested by previous studies.

“This suggests that projected atmospheric CO2 levels in IPCC scenarios are significantly too high, which implies that global temperature rises projected by IPCC models are also too high, even if the climate is as sensitive to CO2 increases as the models imply.”

And Prof Judith Curry, the former chair of Earth and atmospheric sciences at the Georgia Institute of Technology, added: “It is inappropriate to dismiss the arguments of the so-called contrarians, since their disagreement with the consensus reflects conflicts of values and a preference for the empirical (i.e. what has been observed) versus the hypothetical (i.e. what is projected from climate models).

“These disagreements are at the heart of the public debate on climate change, and these issues should be debated, not dismissed.”
