    Economic models significantly underestimate climate change risks | London School of Economics

    Policymakers are being misinformed by the results of economic models that underestimate the future risks of climate change impacts, according to a new paper
    published in the Review of Environmental Economics and Policy.

    They warn that the "integrated assessment models" used by economists "largely ignore the potential for 'tipping points' beyond which impacts accelerate, become unstoppable, or become irreversible." As a result "they inadequately account for the potential damages from climate change, especially at moderate to high levels of warming," due to rises in global mean temperature of more than 2 Celsius degrees.

    The authors draw attention to "a major discrepancy between scientific and economic estimates of the impacts of unmanaged future climate change." They state: "These discrepancies between the physical and the economic impact estimates are large, and they matter. However, physical impacts are often not translated into monetary terms and they have largely been ignored by climate economists."

    Melting Permafrost Emits More Methane Than Scientists Thought | Eco Watch

    Methane is reckoned to be at least 30 times more powerful than CO2 at warming the earth, with some estimates putting its potency much higher still. The good news, research has suggested, is that there is far less methane than CO2 in the atmosphere to worry about.

    The bad news, announced by an international research team, is that previous calculations may have been seriously wrong, and that thawing permafrost is likely to be producing appreciably more methane than anyone had thought....

    Methane and carbon dioxide are both produced in thawing permafrost as dead animal and plant remains decompose. But methane is formed only in the absence of oxygen. Until now, scientists had also thought that more greenhouse gases were formed when the ground was dry and well aerated—in other words, when oxygen was available.

    So they did not expect much methane to be produced by the thawing permafrost. What Dr. Knoblauch and his colleagues have now shown is that water-saturated permafrost soils without oxygen can be twice as harmful to the climate as dry soils—which means the role of methane has been greatly underestimated....

    'Zero tolerance' plan eyed for plastic pollution

    Governments are being asked to move towards a legal treaty banning plastic waste from entering the sea.

    Delegates in Nairobi preparing the way for the UN's environment ministers meeting next week are said to be in broad agreement on the need for tougher action to combat the plastics crisis.

    One idea is to mirror the model of the Paris climate agreement.
