Future Changes in Climate
Sea Level Rise

Continued greenhouse gas emissions at or above current rates would cause further warming and induce many changes in the global climate system during the 21st century that would very likely be larger than those observed during the 20th century.
SRES ,that is, the IPCC Special Report on Emission Scenarios.
There are six scenario groups that should be considered equally sound that span a wide range of uncertainty,as required by the Terms of encompass four combinations of demographic change,social and economic development,and broad technological developments,corresponding to the four families (A1,A2,B1,B2),each with an illustrative “marker”scenario.
A1. The A1 storyline and scenario family describes a future world of very rapid economic growth, global population that peaks in mid-century and declines thereafter, and the rapid introduction of new and more efficient underlying themes are convergence among regions, capacity building and increased cultural and social interactions, with a substantial reduction in regional differences in per capita income. The three A1 groups are distinguished by their technological emphasis: fossil intensive (A1FI), non-fossil energy sources (A1T), or a balance across all sources (A1B) (where balanced is defined as not relying too heavily on one particular energy source, on the assumption that similar improvement rates apply to all energy supply and end use.
A2. The A2 storyline and scenario family describes a very heterogeneous world. The underlying theme is self reliance and preservation of local identities. Fertility patterns across regions c
