Welcome to the blog of the course and textbook Facing up to global warming: What is going on and what you can do about it. This course is run by Professor Nick Gray of the Trinity Centre for the Environment at Trinity College Dublin.

  3. ...global warming ("good" no longer spend cold)... pouring pollutants greenhouse effect into the air is melting the poles. Besides on melting permafrost will liberate into the Atmosphere million Tm of methane with big greenhouse effect. This large amount of freshwater to the ocean could stop deep sea currents which depend on a delicate balance between fresh and salty water and temperatures, (ThermoHaline Circulation) vertical starting in polar areas from surface ↓↓ downwards and continuing go away slow and cold by the bottom loading nutrients and carrying large heat quantities. Deep sea currents move 90% of all the oceans water. Heat from the Sun reaches the equator and currents distribute it throughout the Planet, then...goodbye to our warm climate. The horizontal oceanic currents on surface produced by winds (move 10% of all the oceans water), rotating (Gyres) all by the Coriolis effect, and some others in all levels by the rotation of the Earth from West→East, like the Antarctic circumpolar current, will continue...but the vertical currents produced by the sinking of horizontal currents of dense salty water that reaching the poles where the water is sweeter, less salty, and form cold bottom currents going heat transvasing among different latitudes would stop (why are the Grand Banks fishing in cold latitudes?...because over there is the POLAR ICE, freshwater, different sweet/salty density, salty dense water arriving and sinks in a little salty water environment...nutrients that are removed from the bottom cold water and rise to the surface, phytoplankton that feed on nutrients, zooplankton that feed on phytoplankton, fish that feed on zooplankton)... No polar ice over there will be no vertical currents...could reduce the rise of nutrients to the surface and therefore PHYTOPLANKTON SHORTAGE MAY DECREASING ITS VITAL CONTRIBUTION WITH OXYGEN TO THE ATMOSPHERE (90%)...fish...WINDS in some places of more warm latitudes carry far the surface´s hot water permitting the outcropping ↑↑ to surface of water with plankton and nutrients (the upwelling) from the bottom cold current coming from the pole, forming other Banks fishing (and other zones where phytoplankton oxygen produces), and returning by surface again like warm water towards the poles completing the THC circuit... Without polar ice the sea it could almost stratified into horizontal layers, less salty upwards...more salty downwards with little mixing, little energetic movement of water masses in vertical which is what removes fertilizer nutrients from the bottom cold water, and also produces the THC... Besides lowering salinity of the sea, for that great contribution with freshwater to melt the poles, will increase evaporation (ebullioscopy: the less salt has, more evaporates) producing gigantic storm clouds as have never seen, that together with changing of the ocean currents, could cool areas of the Planet causing a new ice age... Warming...invasion of tropical diseases carried by their transmitter agents, already without the "general Winter" containing them would fall upon the World like a plague...can produce a cooling, a new ice age, like living at the North Pole...and less oxygen in the Atmosphere... It´s not known what will be worse... Go choosing.
