Is global warming at a standstill ?

New Met Office figures have suggested that global warming has stalled over the last two decades.

While the results don't contradict long-term climate change, they do indicate that by 2017 temperatures will have remained practically the same for 20 years. Scientists have pointed out however that factors such as ocean current patterns are likely to be responsible for this stagnant period and that in the long-term temperatures are still set to rise.

"As with all areas of science, our knowledge is continually increasing and it is therefore not surprising that our models and predictive skill will continue to improve," the Met Office has stated. "The fact that the new model predicts less warming, globally, for the coming five years does not necessarily tell us anything about long-term predictions of climate change for the coming century."

"A new scientific model has revised previous figures for the next five years downwards by around a fifth."

Have any of you heard of any hypothesis for why this "standstill" is occurring? Heard of one (actually a combination of three), but don't know if it's any better: 1. High sulfur emissions from Chinese power plants. 2. Decreasing solar activity. 3. Energy being dissipated by increased storm activity. Sorry I don't have the reference. Doug

Little Fish, Doug and BR Have any of you heard of any hypothesis for why this "standstill" is occurring? In Denmark we are puzzled, the best hypothesis we have heard of is the slowdown in climate forcing growth rate. But even this hypothesis leaves many of our questions unanswered. Any of you heard of a better hypothesis? P.S sorry if you already have posted one - to lazy to read all of the posts. I think the essential driver of climate change is completely unchanged as attested by the continued energy imbalance and the steady accumulation of heat in the deep oceans. I think its simply a bifib... [More]

GLOBAL WARMING - WHY THE PENDULUM IS SWINGING As the world approaches the close of a decade of stable temperatures, with recent hints of cooling, in New Zealand and elsewhere, ordinary citizens are starting to realise that there is no substance to the hysteria about human-induced "global warming" created by their governments for political reasons, fanned by news media more interested in attracting readers and viewers with doom and gloom reports of impending catastrophe than presenting the simple facts. Take a few minutes to read this item, to see how you have been misled. The New Zealand Clima... [More]

Antarctic Ice volume is on the increase because there has been an increase in precipitation/snowfall due to a change in the prevailing weather patterns around the continent. This change is because more moist WARM air is been carried into the Antarctic interior where due to the high mountain ranges it is forced out of the clouds due to the lapse rate. The growth of Antarctic land ice is directly caused by Global warming. Many areas of Antarctic sea ice are in fact on the retreat due to rising antarctic sea surface temperatures. Global warming = Climate change. Not all climate change is in a pre... [More]

I saw an article last night (I think it was in a back-issue of "Science.") that explains that Antarctica's lack of warming everywhere except the Antarctic Peninsula, is due to the ozone hole (which still exists) affecting polar atmospheric circulation. I was planning to bring it with me today, but forgot it. It also explained the warm-up of the Antarctic Peninsula. Doug A few years back that was reported in several journals, and makes perfect sense: Ozone is also a greenhouse gas, therefore the lack of it (ozone hole) must lead to cooling...or at least to lesser warming than there where the oz...

A few years back that was reported in several journals, and makes perfect sense: Ozone is also a greenhouse gas, therefore the lack of it (ozone hole) must lead to cooling...or at least to lesser warming than there where the ozone is still intact. And it is precisely that what leads the argument carbon dioxide (also a greenhouse gas) has nothing to do with it ad absurdum. The ozone hole is actually the reason why Antarctica been "protected" by GW. What Doug means by "polar atmospheric circulation" is that the polar vortex has intensified and therefore affected Antarctica weather patterns. When... [More]

The ozone hole is actually the reason why Antarctica been "protected" by GW. What Doug means by "polar atmospheric circulation" is that the polar vortex has intensified and therefore affected Antarctica weather patterns. When the ozone hole disappear the polar vortex intensity will reduce and Antarctica will warm. there is an ozone "hole" over the arctic too. so why would the arctic be warming and the antarctic be cooling when both have seen a reduction is ozone. this looks to me like speculation to protect a faulty theory.

"In the northern polar regions, ozone levels in the early 1990s measured ten percent lower than those estimated in the late 1970s. The Arctic does experience ozone depletion, but to a lesser degree than the Antarctic. Unlike the Antarctic, large-scale weather systems disturb the wind flow in the Arctic and prevent the temperature in the stratosphere from being as cold. Therefore fewe... [More]

More explanation for why the cooling effects of ozone depletion are unique to the antarctic The comparisons show that the two polar regions display fundamentally different character. Observations of the ozone abundance at 70 mbar (?18 km) show that some local ozone depletion has occurred in the Arctic. However, the extreme anomalies associated with the springtime Antarctic ozone hole as observed in many records (frequent removal of 90% of the ozone at this level and sometimes 99%) are not observed in any of the available long-term Arctic records. http://www.pnas.org/.../104/2/445.full Br Corne...
