Sea ice

Hello James,

Welcome to Wikipedia. In response to you comments on the talk page on sea level rise. Please discuss concrete ideas for improving the article, based on reliable sources. If you think A is wrong, provide a source and suggest better descriptions of how it should be.

Content-wise: We do not assume linear melt in the current article. The contribution section for instance has a description of marine ice sheet instability, a very nonlinear phenomenon. Also the projections section has nonlinear projections of ice melt. Climate scientist are very aware of the different nonlinear effects in ice melt and we've relied on reliable sources of those experts. Femkemilene (talk) 15:28, 14 October 2018 (UTC)
