@EJWagenmakers @mikofLohr Eh, heren? Dit schrijft ze in haar PeerJ preprint. Een 'klimaatontkenner' die erop wijst dat het poolijs 2x zo snel afsmelt? En o ja, de link naar deze paper staat *niet* in dat bioscience-ding. https://t.co/zjGPpAljE3 https://t.co/NkapVdCR8c

@JamesHT Nonsense. I am a zoologist with a Ph.D. and plenty of peer-reviewed scientific papers, listed here https://t.co/HrMcMZXf7O I support my scientific #polarbear arguments with refs from scientific lit. https://t.co/gBveassiX1 Your friends are petty, ignorant, & unscientific.

This level of summer sea ice - 5 mk2 or less - was not predicted to occur until about 2050, which future #polarbear extinction was based upon. See my hypothesis paper https://t.co/gBveassiX1 and my new book https://t.co/t4GvnAjrQP
