Climate Myth...
It's cooling
"In fact global warming has stopped and a cooling is beginning. No climate model has predicted a cooling of the Earth – quite the contrary. And this means that the projections of future climate are unreliable." (source: Henrik Svensmark)
When looking for evidence of global warming, there are many different indicators that we should look for. Whilst it's natural to start with air temperatures, a more thorough examination should be as inclusive as possible; snow cover, ice melt, air temperatures over land and sea, even the sea temperatures themselves. The key indicators of global warming shown below are all moving in the direction expected of a warming globe.
Indicators of a warming world based on surface, satellite, and ocean temperature measurements, satellite measurements of energy imbalance (the difference between incoming and outgoing energy at the top of the atmosphere), and of receding glaciers, sea ice, and ice sheets, rising sea level, and shifting seasons.
The question of global warming stopping is often raised in the light of a recent weather event - a big snowfall or drought breaking rain. Global warming is entirely compatible with these events; after all they are just weather. For climate change, it is the long term trends that are important; measured over decades or more, and those long term trends show that the globe is still, unfortunately, warming.

[DB] Please separate these questions into individual comments placed on more appropriate threads; as constructed this comment amounts to a Gish Gallop & thus needs no refuting. Thanks!
[DB] "The slow warming is of interest only to climatologists and in no way is a problem for mankind."
Unsupported, and off-topic, handwaving. See the "It's not Bad" thread.
Moderation complaints snipped.
The slow warming is of interest only to climatologists and in no way is a problem for mankind.(-Snip-).[DB] Your sudden, laser focus on short, statistically insignificant timescales is rather puzzling, given your earlier comment:
Repetitive complaints about moderation snipped.
Unsupported summary musings (i.e., handwavings) struck out. Please stick to the science, please.
What do you guys make of this? http://wattsupwiththat.com/2013/03/11/is-ocean-heat-content-data-all-its-stacked-up-to-be/
Scliu, you're more likely to get a response if you ask a specific question.
Also, given the source, (Bob Tisdale) it's pretty obvious what people will make of it. "Tisdale at it again, after being repeatedly shown to be wrong".
Here's a link. http://wottsupwiththatblog.wordpress.com/2013/05/07/a-challenge-from-bob/
scliu94 - only in the mind of a climate science contrarian can the ocean heat data be unreliable so as to be unable to tell us the oceans are warming, yet reliable enough to confirm that the warming is natural!!
An insurmountable hurdle for contrarians is that the largest natural component for warming the oceans - the sun- has seen a decline in radiation output over the last 3 decades, which should have seen a cooling of the oceans. Instead the oceans the oceans have warmed substantially - as they should when increased concentrations of greenhouse gases trap more heat in the oceans.
