Sentences with phrase «mean surface temperatures began»

Once again under the widening impact of this full hour of extra solar radiation, global mean surface temperatures began to warm.

Not exact matches

However, this doesn't mean that CO2 based Anthropogenic Global Warming began in 1950, because if you look at the Met Office — Hadley Center HadCRUT4 Global Surface Temperature record for the last 163 years you can see that temperatures didn't warm during the 1950s, nor the 60s:

Current «cool» phase of the PDO began in late 1998 / early 1999 (certainly not 2008), and when it flipped it generally meant cooler sea surface temperatures along the west coast of N. America but warmer temperatures on average over other other broad regions of the Pacific.

Besides I strongly oppose (like R.Pielke and many others) the idea that the «global time average of the surface temperature» has any physical meaning or is a valid metrics to measure the «climate» and I can't see the beginning of a valid reason why it should correlate to any relevant dynamical parameter.

The Summary for Policy Makers at the beginning of AR5 defines «the past» by referencing temperatures to the global mean surface temperature averaged over 1985 - 2005.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.

The study refutes a claim that the planet's mean surface - temperature increases began to slow down in 1998, commonly referred to as a global warming «hiatus» phenomenon.
