Or we could take 30 years for climate purposes. And we could differentiate between global warming and climate change. I'm also intrigued how anything in the present can refuse to play ball with a projection. Did it also refuse to play ball after the 70s? And 1976 Dev.

Remember when he did a Sam Clemens. Hilarious. One of the illiterati was devastated. http://wattsupwiththat.com/2012/04/21/real-science-announces-the-death-of-steve-goddard-2/

http://forum.netweather.tv/topic/76448-scepticism-of-man-made-climate-change/page-55#entry2935578 I'm very interested in what scientific alternative views to the consensus have been postulated this morning. Were they written in invisible type? Or does this count as one. Genuine alternative views supported by reasoned scientific evidence is always welcome and by that I don't mean drivel from Watts and Goddard. Trouble is these views seem to be in short supply.

http://forum.netweather.tv/topic/76448-scepticism-of-man-made-climate-change/page-55#entry2935518 Can't argue with that. If any article in the sun was 100% correct it would indeed be priceless.

That should read, science has moved on. Scientists often change the direction of their thinking on the basis of on-going research and gaining more knowledge about extremely complex issues. That's what science is all about and has been for centuries. And as a matter of interest what do think current day thinking is based on? And to reverse that. What is current sceptic/denier thinking based on?

Apologies John I've no wish to hijack any debate so will keep out in future. Just to add I think debate is debatable

Complete twoddle and not worthy of a primary school debate.

Yes the sun is of course the ultimate driver and has been the mechanism in the past for high latitude climate change. The climate responded to changes of insolation forcing due to orbital variations. Such as changes in orbital eccentricity, obliquity, procession of the equinoxes, changes in orbital inclination and the Milankovitch theory although the latter is still up for grabs. There are also Heinrich events but we won't go there. But we aren't talking about them but rapid changes, geological time speak, over the last 150 years. As you pointed out global dimming plays a role but some recent papers have made the point that Nick made other changes seem to be too small to make a significant difference. There have of course been other theories such as variations in the earths magnetic field but they are just theories and nothing so far has been presented to replace the current thinking, or as far as I can see, even come close.

Well this is different. How does melting in #Greenland sound ? Discover our sonifications here http://www.polarseeds.org/sonified-annua

With today's snowfall, it is now the snowiest Jan-Feb on record at Central Park. 48.5" beats 47.2" in 95-96. https://twitter.com/NWSNewYorkNY/status/435859915056623616

They never said it would go on unabated and rather than run around like headless chickens various climate scientists have written papers on the hiatus which in any case was only a slow down of the surface temps and not a halt of climate change, If by chance you feel the need to catch up on the latest science on the subject rather than rely on aimless rhetoric quite a fair summary here. http://www.realclimate.org/index.php/archives/2014/02/going-with-the-wind/

I rather think that was the Tambora volcano eruption. The sun was only indirectly involved, the main culprit being volcanic ash reducing the solar input.

I rather think they didn't forget, see the latest report and in 2010 Julia Slingo said a) Prolonged snowfall and low temperatures, comparable with conditions seen during November and December 2010 are within the range of natural climate variability observed over the past 50 years. b) The latest available regional climate projections for the UK (UKCP09) indicate a reducing likelihood of severe winters in future, due to the long-term warming climate. Natural climate variability implies that severe events remain possible but with reduced likelihood. http://assets.dft.gov.uk/publications/pgr-resilience-briefing-pdf/report.pdf

Ye s that had crossed my mind as well.

Increase in Arctic Cyclones is Linked to Climate Change, New Study Shows Winter in the Arctic is not only cold and dark, it is also storm season when hurricane-like cyclones traverse the northern waters from Iceland to Alaska. These cyclones are characterized by strong localized drops in sea level pressure, and as Arctic-wide decreases in sea level pressure are one of the expected results of climate change, this could increase extreme Arctic cyclone activity, including powerful storms in the spring and fall. A new study in Geophysical Research Letters uses historical climate model simulations to demonstrate that there has been an Arctic-wide decrease in sea level pressure since the 1800's. “This research shows that the Arctic appears to be expressing symptoms expected from ongoing climate change,†said Dr. Stephen Vavrus from the University of Wisconsin-Madison. “The long-term decline in atmospheric pressure over most of the Arctic is consistent with the response typically simulated by climate models to greenhouse warming, and this study finds a general corresponding increase in the frequency of extreme Arctic cyclones since the middle 19th century.†Tracking changes in Arctic cyclone activity through time, Vavrus calculated a statistically significant, though minor, increase in extreme Arctic cyclone frequency over the study period, with increases strongest near the Aleutian Islands and Iceland. Dr. Vavrus suggests that, as of yet, the effect of climate change on Arctic cyclone activity has been minimal, but that future changes in polar climate will drive stronger shifts. “One societally relevant implication is that more storminess probably means more erosion of Arctic coastlines, especially in tandem with declines in buffering sea ice cover and increases in thawing coastal permafrost,†concluded Dr. Varnus. “Erosion of Arctic coastlines has already been growing more severe during recent decades, and this study points to a contributing factor that will likely become an even more recognizable culprit in the future.†http://eu.wiley.com/WileyCDA/PressRelease/pressReleaseId-110301.html

Last Sunday was like a reverse oasis. A spring-like day in the middle of February. Nature is beginning to stir but the overriding impression after this winter was one of tranquility.
