Climate unknowns include the rate of sea level rise, ozone loss, how the Gulf Stream will react and what it possibly means, the Earth’s response, and the potential for extra methane release from methane clathrates, stored at continental margins. There are many more climate unknowns, for example elaborated in this article https://thinkprogress.org/what-are-the-unknown-unknowns-of-global-warming-1438d934bdee 0:04 #1 Ozone…

This heatwave across much of the northern hemisphere could continue for weeks, and possibly even months. And accelerated warming in the Arctic compared to the rest of the planet could be a key contributor. https://www.newscientist.com/article/2174889-warming-arctic-could-be-behind-heatwave-sweeping-northern-hemisphere/ Jennifer Francis (Rutgers University), speaks March 2018 about weather changes. And how are those related to climate change? Full talk…
