Temperatures over the last 10,000 years

Here is a very interesting little graph. This peer reviewed graph shows the average global temperatures over the last 10,000 years.

  1. Even if the overall temperature for the last 10,000 years is falling, the high output from the burning of fossil fuels could possibly the delay the next ice age by several thousand years. In the meanwhile melting polar ice could cause one of two things. 1st, melting sea and glacial ice could raise sea levels around the world by several feet, which would inundate the maldives in the indian ocean and the atolls and low lying islands in the oceania islands of the pacific ocean. Secondly another possible outcome is another possible consequence of melting polar ice and glacial ice is the dumping of fresh water into the gulf stream or the north atlantic current. This current warms England and northern Europe giving them their warmer climate. The last few years England’s and northern Europe’s winter has been getting noticeably colder and snowier.
    This could be a sign that the gulf stream could be starting to get disrupted by the lower levels of salt. The salt allows the colder, more denser current to sink to the bottom and bring the warmer, less dense water to the surface and it flows to Europe where it gives the warm climate by transpiration and the winds that blow over the warmer ocean carries the warmer air towards northern europe. Then the warm current becomes cooler, denser and it sinks and the current flows back to where it started, gets warm and rises to the surface again in the tropics and the cycle repeats its self. But the fresh water from melting polar ice is throwing the current off balance by dumping too much, cooler denser water into the current. Since there is more fresh water than salt water, the current will weaken and Europe will get colder. If this continues London, paris, Amsterdam and Dublin will have a Climate like labrador in northeastern Canada.

    • You might be unaware of this, but recent studies in the Arctic of what’s called “arctic tea”. The BBC covered it during their radio 4 programme “Material World”, you can listen the show as a podcast. It was on the 28th of April.

      Essentially its algae affecting the melting of the ice, perhaps to a greater effect than previously understood. It’s also a likely CO2 sink. Previously not taken into account.

      Nature covered the Agulhas leakage and how it appears to be stabilising the North Atlantic de-salination effect. Again not understood or modelled. The leak may be a misnomer, it’s actually pumping 30 times the volume of the Amazon flow around the southern tip of Africa, heading west and North. It’s water is warm highly salty. It feeds 2/3’s of the water for the gulf stream. It is increasing in response to global warming, replacing the loss of sea density.

      All of which gives us the more important underlying message that our understanding of the climate is still very much in it’s infancy and our projections are not based on fact, as so much suggestion. Don’t give up that beach hut just yet.

  2. This Cooling in Europe will not be long due to the rising levels of C02. Europe will return to it’s current state like it is now within 50-60 years of cooler weather. As for the maldives and those beautiful pristine, low lying of the indian and pacific oceans their only hope for survival are if they all construct a levee or a sea wall.
