Den stora tråden om global uppvärmning/växthuseffekten

“The IPCC once again reports that there is little basis for claiming that drought, floods, hurricanes, tornadoes have increased, much less increased due to” greenhouse gases, University of Colorado professor Roger Pielke, Jr. tweeted Sunday night.

For example, the IPCC’s report noted that “there is only low confidence regarding changes in global tropical cyclone numbers under global warming over the last four decades.” Pielke pointed out this inconvenient data.

Much like the IPCC’s 2013 climate assessment, the new special report confirmed what Pielke and others have said for years about the relationship between global warming and extreme weather.

But don’t expect to hear that from many other media outlets, especially those that often cite individual weather events as evidence of man-made warming.

Extreme weather events:

Extreme weather events have not gotten worse which can be shown from statistics on tropical storms and extra-tropical storms, tornadoes and various local floods.

Answering the question (in the paper DI); From my point of view, there is a discrepancy between the IPCC's scientific report and its Summary for Policymakers. The later is by comparison dire. How should one understand this?

From my point of view there is an unfortunate tendency, especially in the media but even from some representatives of the IPCC, as we have seen in the last report, to exaggerate weather phenomena and create an atmosphere of exaggeration among the public to gain support for drastic measure to reduce greenhouse gas emissions.

Here it is the scientific results that have had to give way, if they are not dramatic enough. The latest report (2013) is less dramatic than the IPCC's previous ones, playing down extreme weather events and reducing climate sensitivity.

This does not fit the simple catastrophic picture, so therefore they have re interpret this. Some activists even have been able to interpret the extremely cold weather in USA during the last winter as a product of climate change. It is this kind of thing that causes science to lose its credibility.

-US heatways are no more commen than 1900.
-Greenland ice sheet are not shrinking any faster than 80 Years ago.
-Global fire area has declined since 2003
-No detectable human impact of hurricanes

Det finns mig veterligen inget som tyder på att extremväder har ökat. Rent principiellt bör extremväder istället minska med ett varmare klimat eftersom det inte är temperaturen som sådan som driver extremväder, utan temperaturkontraster, vilka minskar i ett varmare klimat. Dock måste den totala globala mängden regn öka i ett varmare klimat.

En annan ”klimatnyhet” ni inte lär få höra något om i media: havsisen i Arktis är nu större än den varit någon gång sedan 2009

Minns du Krösa-Maja, den skinntorra gumman i Astrid Lindgrens böcker om Emil i Lönneberga? Så fort benen bar henne sprang hon mellan de småländska gårdarna med det senaste skvallret, utbroderat med detaljrika överdrifter och rena fantasier, pepprat med skrock och vidskepelse – och med ett jämrande ”hujedamej” på läpparna. ”Skräm inte barnen”, manade Emils mamma henne. ”Jo, gör det!” sa en storögd Emil, kittlad av de hemskaste historier om farliga sagoväsen, om olyckor och död. Men räddast av alla var förstås Krösa-Maja själv.
