How is the change in ocean currents ( El NIno n La Nina ) related to global warmin? i though it had everythin to with Co2 levels n all??

  1. Definitely sea changes when iceberg melt like the massive ones it raises the sea levels,that what happening right now

    The air deteriorating is caused by air pollution like car fumes, fumes from factories smoke from any source that isn't needed

    Take a look at China I sure wouldn't like to be breathing it that much pollution.

    South Australia is having its worse drought in my life time and summer was exceedingly hot as well

    I hope next year is better


  2. El Niño / La Niña is related to global climate, but not to global climate change.

    In some years, a persistent high pressure area forms over northern Australia / Indonesia, which dramatically slows the tropical trade winds over the Pacific. When this happens, warm equatorial water slows its circulation and, instead of moving back south to cool, stays in the equatorial region and bakes. This pool of very warm Pacific water causes changes in the global climate, most obviously an increase in mean global surface temperature. That's an El Niño.

    But over the long term, the warmth caused by El Niño is just a random fluctuation. In some years the situation reverses, Pacific trade winds increase, and the planet cools. It goes back and forth. Right now, we're in the grip of a cooling La Niña effect. But this too shall pass. These effects cause, in the worst case, a global change 0.1° to 0.2°C.

    "Global warming" in the sense of permanent climate change is caused by human beings emitting greenhouse gases into the air, especially CO2. The trend has been unremittingly upward since the industrial revolution, and shows no signs of slowing down. The increase in greenhouse gases since 1750 has caused an increase of about 1.2° C since that time -- although 0.3° of that has been offset by sulfur dioxide pollution, which cools the earth.

  3. Yea, co2 was to blame until this year.  Now ocean currents are being blamed.

    This is because we have such a small knowledge about the actual working of the climate.  As we learn more we get a better understanding.

    Now most scientist are agreeing that the Sun, not man is causing the Earth to warm.

  4. I believe your information is correct.  I've never seen anything from a qualified source that suggested there was a connection.  It's usually the answer for the people who post "It's snowing on my carport.  Doesn't this disprove Global Warming?"

  5. ENSO affects weather.  Climate is the effect of weather over time, so the ENSO is noise climatologist must try to factor in their estimates.

    ENSO has cycles, but their duration and intensity are chaotic.  Some claim ENSO trends positive because of AWG, but there is no conclusive evidence of such a claim, and remains hypothetical.  Since there is a chaotic element, an algorithm based on a sample of random numbers could also mimic such a trend.

    Some people confuse (or use as a subterfuge) ENSO as an indication of warming ocean temperatures.  This is NOT the case.  ENSO is a surface phenomenon, and can go from positive to negative with no change in overall change in ocean temperatures.

    I've seen about everything under the sun attributed to ENSO in the 28 years I've been aware of it.  Some may be true some simple conjecture, but the best way to think about it is it's just ocean weather, and just as unpredictable as atmospheric weather.

  6. Its everything to do with Global Warming because

    changes in sea and ocean temperatures is whats making the ice caps melt.  Hence making sea levels rise.

    The El Nino is a global coupled ocean-atmosphere phenomenon. Its where the surface temperatures in the Pacific Ocean fluctuate, sometimes causing intense storms and rainfall for parts of the southern hemisphere including Darwin and Indonesia. Sometimes even causing Hurricanes.

    ENSO is a set of specific interacting parts of a single global system of coupled ocean-atmosphere climate fluctuations that come about as a consequence of oceanic and atmospheric circulation. The irregularity of ENSO makes predicting it of high interest, as it is demonstrably connected to seasonal, even yearly, regional climatic effects on large areas. ENSO is the most prominent known source of inter-annual variability in weather and climate around the world (about 3 to 8 years), though not all areas are affected. ENSO has signatures in the Pacific, Atlantic and Indian Oceans. El Niño changes the distribution of rainfall, causing floods in some areas and drought in others.
