add Global worming as consequence

With hotter weather and the salinity of ocean currents and the climate being all fudged up, won't there be a deadly increase in the number of hatched larvae of various, potentially pesty, insects ? :( Global warming is the first phase - after it comes Global worming, with the worms devouring all the plantlife and the Earth turning into a withered desert. Not to be an alarmist, but we should add this. ;) --ZemplinTemplar (talk) 20:24, 28 August 2012 (UTC)[reply]

    Climate change, by warming water and reducing river flows, has caused production losses at several nuclear and coal-fired power plants in the United States and Europe in recent years and will lead to more power disruptions in the future, researchers report.

Food security mapping

File:DroughtMaps.jpg

Enescott, I'm always happy to see your high caliber suggestions, even if I don't always agree. I'm glad to see you addressing food security. Not long ago, NCAR published maps of likely drought conditions. That map shows a v-e-r-y different (ie vastly more restricted) agricultural situation in 80 years. For reference, the worst of the 1930s Dust Bowl registered around -6 on this scale, and that was relatively limited in time and scope. Compare the DustBowl-or-worse regions of the 2090 map from NCAR with the areas marked increased productivity on the map you posted. There is a whopping mismatch, at least to my eye. What do you think? Can we report on differing projections of major change ahead? NewsAndEventsGuy (talk) 16:43, 17 July 2012 (UTC)[reply]

PS BTW, I have not reviewed the underlying report for your map and only just noticed its fineprint about it showing possible benefits of carbon fertilization. Do you know if they factored in water, changes in avg temps and extremes, and timing of all those as applied to crops and ag infrastructure? NewsAndEventsGuy (talk) 16:47, 17 July 2012 (UTC)[reply]
Hi. A description of the study is available here: Cline (2008). In my view, it is broadly consistent with the IPCC's findings - adverse impacts at low-latitudes and possible benefits at high-latitudes. I think it would be an improvement if the drought map is added to the article as well.
I should note that the text presents the IPCC consensus view, and explains why food projections are uncertain. The map's caption also mentions that it only reflects the findings of one study. Enescot (talk) 17:46, 18 July 2012 (UTC)[reply]

James Hansen's excellent chart

Frequency of occurrence (vertical axis) of local June-July-August temperature anomalies (relative to 1951-1980 mean) for Northern Hemisphere land in units of local standard deviation (horizontal axis). Temperature anomalies in the period 1951-1980 match closely the normal distribution ("bell curve", shown in green), which is used to define cold (blue), typical (white) and hot (red) seasons, each with probability 33.3%. The distribution of anomalies has shifted to the right as a consequence of the global warming of the past three decades such that cool summers now cover only half of one side of a six-sided die, white covers one side, red covers four sides, and an extremely hot (red-brown) anomaly covers half of one side..

I'm sure you can find a place for this. Sagredo⊙☿♀♁♂♃♄ 18:58, 5 August 2012 (UTC)[reply]

Thanks for that - I'll have a look to see where it can go. It may also be worth adding to other articles, e.g., extreme weather. Enescot (talk) 22:54, 6 August 2012 (UTC)[reply]
Yes, very nice. I like the explanation, too. But perhaps there needs to be little more explanation that this represents how nominally "random" weather events are being driven as if by a loaded die? ~ J. Johnson (JJ) (talk) 22:45, 28 August 2012 (UTC)[reply]
I agree that the caption's explanation could be better. At the moment its rather technical. The analogy with the loaded die is certainty referred to in Hansen et al's paper.
On another point, I have changed my mind about adding the Hansen et al image to the article. There appears to be some skepticism about the paper [1], but I don't know how valid it is. In my opinion, the article should be highly conservative in what it says. I was therefore thinking of moving the Hansen et al image to physical impacts of climate change, with it being explicitly attributed to Hansen et al. This probably also applies to the map of climate change impacts on agriculture by Cline, which NewsAndEventsGuy has criticized. Enescot (talk) 03:18, 13 September 2012 (UTC)[reply]
