    Measurements from the 1960s to the early 1990s, backed up by a wide range of data and a number of independent studies, showed there were substantial declines in the amount of the sun's energy reaching the Earth's surface. This reduction is known as "global dimming". The observed "dimming" has strong regional differences across the globe.

    If you want to see global warming's signature, look to the Arctic. Up north, the air is warming and the ice is melting. As all of that reflective ice goes away, the Arctic Ocean is soaking up more sunlight, further enhancing warming. Melting Arctic ice is also contributing significantly to sea level rise.

    Acidity is measured by its pH (power of hydrogen) value. Fresh water has a pH reading of 7. Readings below that are considered to be acidic. Those above 7 are alkaline. Surface sea water had a reading of 8.2 a century ago.

    The world is getting warmer, countering the doubts of climate change sceptics about the validity of some of the scientific evidence, according to the most comprehensive independent review of historical temperature records to date. Scientists at the University of California, Berkeley, found several key issues that sceptics claim can skew global warming figures had no meaningful effect.
