People who claim we can
stop worrying about global
warming on the basis of a cooler year or a cooler
decade — or just on questionable predictions of cooling — are as naive as a child mistaking a falling tide, or a spring low tide, for a real long - term fall in sea level.
There will undoubtedly also be a number of claims made that aren't true; 2008 is not the coolest year this
decade (that was 2000), global
warming hasn't «
stopped», CO2 continues to be a greenhouse gas, and such variability is indeed predicted by climate models.
This means you can't use such short periods to «prove» that global

Your side, the side that says human emitted CO2 is the primary driver of climate change, and which (hubristically) says that natural variation can not explain all the
warming we've seen, can not explain why the
warming has apparently
stopped for almost two
decades.
Here's a video to watch so you'll be prepared the next time some idiot tries to tell you that the IPCC started using «climate change» instead of «global
warming» because the
warming stopped in the last
decade.
The drop in trend from its maximum of 0.19 deg C per
decade to 0.15 deg C per
decade shows global
warming has
stopped.

Santer et al. also shoot down the myth that a slowed rate of
warming over a
decade can prove that global
warming has magically
stopped:

decade warming.
If you believe the Earth
stopped cooling, and is now
warming, you should be able to nominate the
decade (at least), when this momentous change in the trend occurred.
Empirically, I think there is good evidence that the overall climate relaxation time is order of 1 - 3
decades — that is, although there is good reason to think that the Earth had «started to cool» by the middle of the last solar cycle (about the time it
stopped even thinking about getting overall
warmer) it has taken a solid
decade for actual cooling to think about revealing itself, and that is still masked by a lot of noise in the complex system.
I think James» point about the last
decade is not that global
warming has
stopped (implying low or zero climate sensitivity) but that it has not accelerated to the extent that it would have if climate sensitivity were very high (above, say, 4).
So even if we were to
stop emitting greenhouse gases right now, it's going to continue
warming for at least the next two
decades.
And so, over the
decade, alarmist climate scientists tried to fool the public by stonewalling («it's the
warmest decade on record,» which doesn't mean the
decade was
warming), denying the facts («the allegation that annual global mean temperatures
stopped increasing during the past
decade has no basis in reality»), or outright lying («the world is
warming even more quickly than we had thought»).
A certain amount of continued
warming of the planet is projected to occur as a result of human - induced emissions to date; another 0.5 °F increase would be expected over the next few
decades even if all emissions from human activities suddenly
stopped, 11 although natural variability could still play an important role over this time period.12 However, choices made now and in the next few
decades will determine the amount of additional future
warming.
But over the
decade, while the planet
stopped warming and even tipped toward cooling, what did the public hear, usually through the mass media, from the alarmist climate agencies and the IPCC?
The only «fact» we have here is that it appears to have
stopped around the end of 2000, and has cooled slightly since then (at a cooling rate similar to the
warming rate experienced from 1850 to 2000, or around — 0.06 °C per
decade).
By calculating this Libration forcing on a time scale, you will see, that global

decades until 2043.
You present a «straw man»; i.e. you make the untrue assertion of «continued
warming» when the
warming stopped nearly two
decades ago.
That's why climate is generally defined in terms of multiple
decades of data, why Santer et al. find that you need at least 17 years of data to compare models and the real world, and why real scientists don't say «OMG GLOBAL
WARMING HAS
STOPPED!»

decade is never, never sufficient in concluding that
warming has
stopped — this is a basic principle of climate science.
They deliberately deleted the last
decade of data because it shows that global
warming has
stopped.
And when that natural variability is greater on short time scales than the CO2 signal, then it's all but inevitable that there will be
decades where
warming appears to
stop only to start up again later.
The reasons for that are many: the timid language of scientific probabilities, which the climatologist James Hansen once called «scientific reticence» in a paper chastising scientists for editing their own observations so conscientiously that they failed to communicate how dire the threat really was; the fact that the country is dominated by a group of technocrats who believe any problem can be solved and an opposing culture that doesn't even see
warming as a problem worth addressing; the way that climate denialism has made scientists even more cautious in offering speculative warnings; the simple speed of change and, also, its slowness, such that we are only seeing effects now of
warming from
decades past; our uncertainty about uncertainty, which the climate writer Naomi Oreskes in particular has suggested
stops us from preparing as though anything worse than a median outcome were even possible; the way we assume climate change will hit hardest elsewhere, not everywhere; the smallness (two degrees) and largeness (1.8 trillion tons) and abstractness (400 parts per million) of the numbers; the discomfort of considering a problem that is very difficult, if not impossible, to solve; the altogether incomprehensible scale of that problem, which amounts to the prospect of our own annihilation; simple fear.
If we've been building up heat at the rate of four Hiroshima bombs every second, why has
warming stopped for the last

For example, while the planet has been
warming for
decades, that doesn't mean winter will
stop happening or that places will no longer experience cold periods.

These cold winters we have been having lately might
stop them spreading, and in fact will benefit our native British species as several invasives have spread due to the

decade.
In doing so we'll also prevent some 1.5 million premature deaths annually due to improved air quality.Soot Comes Out of the Atmosphere in Weeks, Not
Decades Since soot — which in this context comes from older diesel engines and burning other fossil fuels, industrial sources, inefficient biomass cookstoves used in many developing nations — comes out of the atmosphere in a matter of weeks, not decades or centuries like carbon dioxide or other greenhouse gases, removing the source of pollution is highly effective in both stopping the warming effects as well as improving air q

The proposed rapid acceleration of sea level rise when surface
warming has slowed (or
stopped, if your prefer satellite data) and when ocean
warming is in the hundredths of a degree per
decade range seems very strange.
As I clearly demonstrate in my Hub, there is also considerable evidence that global
warming has taken a breather over the past
decade and appears in some data sets to have
stopped.
It's that second part which really as implications for reducing
warming from soot.Effects of Black Carbon Pollution
Stop Quickly Once Source is Removed The good news about black carbon and global
warming is this: Unlike greenhouse gases which can remain in the atmosphere for
decades or even centuries, black carbon particles come out of the atmosphere very quickly once the source of pollution is removed.

stopped to consider that the very people who have been calling for global governance for
decades are the leading advocates of anthropomorphic global
warming..?

stop warming but because of the ongoing reduction in forcing, the global average temperature reaches its maximum in not much more than a
decade.
