The Oceans Are Acidifying at the Fastest Rate in 300 Million Years. How Worried Should We Be?

Biologists at the Alfred Wegener Institute in Germany tallied up much of the field research that’s been done to date and compared it against the fossil record, in an attempt to get a broad overview of the effects of acidification on corals, molluscs, echinoderms, crustaceans and fishes.  The results, published this week in Nature Climate Change, aren’t exactly encouraging:  “Our analysis demonstrates that all considered groups are impacted negatively, albeit differentially, even by moderate ocean acidification.”

Climate science will soon fill a role similar to weather forecasting:  Helping humanity deal with the impacts on a regular basis.  Up until recently, climate science has been used to determine whether or not the world is warming and what’s causing this warming.  But with the necessary scientific evidence now in place, climate science will soon be used to help guard against the risks posed by climate change.

Carbon Targets, Carbon Taxes, and the Search for Archimedes’ Lever

A real policy, no matter how kludged and compromised, is always more efficacious than a theoretical policy.  A carbon tax is the best (and only necessary) climate policy only on a blackboard or in a spreadsheet.  In the real world, power and interests matter and anything that alters them in the right direction is desirable.  Just as a carbon target means nothing until the policies and capabilities are in place, a carbon tax will only ever be as high as political economy allows.

Who Are the Big 5 in the Carbon Trade?

When we talk about a country’s carbon emissions we generally only consider those that occur within its borders.  But where does the fuel for those emissions come from?  And where do the products a country makes go?

In this second part of our series The Carbon Trade we look at who the big traders of carbon are.  We’ll analyze the major importers and exporters of fuels and products and in doing so explain much of how carbon moves around the world, both before and after its combustion.
