www.physorg.com February 23rd again … climatologists are looking at features other than greenhouse gases as drivers of climate. The oceans are known to play a role – such as ENSO events and El Ninos. The latter is actually impacting on global temperatures in 2009 and 2010 and as oceans cover over 70 per cent of the global surface they obviously play an important role in our climate. It is thought they are a kind of thermostat, storing energy from the Sun in the top 10 feet of sea-water. Heat and moisture from the oceans are transferred to the atmosphere, and vice versa. NASA GISS and the Met office think 2010 might be the warmest year ever because of the current El Nino which is taking place and adding to the global average temperature.

Chains of mountains march across the sea bottom and others occur as isolated peaks or volcanoes, sometimes surfacing as islands. Most of them are unexplored.
