With global GHG emissions and concentrations continuing to increase; with climate change intensifying changes in ecosystems, ice sheet deterioration, and sea level rise; and with fossil fuels providing more than 80 % of the world's energy, the likelihood seems low that cooperative actions will prevent increasingly disruptive climate change over the next several decades.

If the oceans had been losing energy over the same period the troposphere was seeing the «pause» or the sea level declining, or the net glacial mass of Greenland and Antarctica increasing rather than declining, then the «pause» would be confirmatory evidence that maybe the climate is not as sensitive to increasing GH gases.

Substantial weakening of the polar cell due to increase in sea - level pressure over polar latitudes leads to a negative trend of the winter AO index.

Simulated losses are moderate (< 0.25 mm per year sea level) over the 21st Century, but generally increase thereafter.

The 2009 State of the Climate Report of the US National Oceanic and Atmospheric Administration (NOAA) tells us that climate change is real because of rising surface air temperatures since 1880 over land and the ocean, ocean acidification, sea level rise, glaciers melting, rising specific humidity, ocean heat content increasing, sea ice retreating, glaciers diminishing, Northern Hemisphere snow cover decreasing, and so many other lines of evidence.
