CO2 emissions reductions have the power to avert additional warming though
emissions reductions cannot return global temperatures to preindustrial levels.
Climate warming in future is determined not by past CO2 emissions, but by modern
emissions.

Combining the use of neodymium isotopes, high-resolution elemental
analysis, and biomarkers, they trace changes in sediment origin and river
runoff. Regional interactions within the climate-lake-FIS system led to abrupt
drainage cycles of the FIS in to Black Sea watershed. This raised the BS water
level by around 100m.
10. Turbulent convection in liquid metal with and without rotation

The convective behavior of liquid metal (Pr＜＜1) differs from that of moderate Pr fluids. A
transition between rotationally constrained and weakly rotating turbulent
states is identified. This transition difference may explain classes of
magnetic fields observed on the Gas and Ice Giant planets.

methacrylic acid epoxide arises from decomposition of the OH adduct of
metha- cryloylperoxynitrate (MPAN).
