Read here. Whether it's vegetation or animal species, global warming produces environments and local climates that allow species to thrive and prosper. Scientists have now concluded the same will happen for marine life around Australia, including sharks, turtles and the overall fisheries biomass. Excellent!
There is a fly-in-the-ointment, though. A huge caveat actually. The scientists used a variety of computer models to come to this conclusion. First, they used output from an IPCC climate model (the 'A2' warming scenario); then a ocean climate model was used based on the A2 output; that model's output was then fed into a "suite" of models; and finally, that output was fed into a dozen marine food web models. Yikes!
Objectively, the likelihood of a correct prediction from a serial chain of model outputs is probably as low as someone picking the correct six numbers (from zero to 99) for the mega-million lotto - that's a really low probability of success. Unfortunately, after spending billion on computer models, they're still nothing more than extreme crystal ball gazing with serious problems.
"In the concluding sentence of their paper, Brown et al. state that the primary production increases suggested by their work to result from future IPCC-envisioned greenhouse gas emissions and their calculated impacts on climate "will provide opportunities to recover overfished fisheries, increase profitability of fisheries and conserve threatened biodiversity," which is an incredibly nice set of consequences to result from something the world's climate alarmists claim to be an unmitigated climate catastrophe."
