IPCC's Global Warming 'Consensus' Falls Apart

By -
While it is about two and a half years late, the last nail has gone into the coffin. Before you react, read the post at the link. The IPCC's reports have been judged to be unreliable.

Do I still believe humans, on balance, warm the planet? Yes! But, at a much slower rate than the IPCC has predicted. You've been reading that the entire history of this blog. That opinion of mine has been boosted by a resource I recently discovered. Dr. James Hansen of NASA, one of the world's strongest proponents of the catastrophic global warming theory, has been keeping a running verification of his famous 1988 forecast. See below.
Dr. Hansen's green line ("scenario A) represents the temperatures that were supposed to conform to the rising levels of CO2 we have in the atmosphere today. Scenario C was the expected temperatures if CO2 levels started dropped in the 1990's which, of course, didn't happen. Actual temperatures are even cooler than if CO2 levels had been greatly reduced! That hardly corresponds to the IPCC's hypothesis that CO2 is the dominant driver of climate.

It is not at all clear that slow warming is a bad thing, especially since earth's temperatures were warmer than today's in the Roman Warming (~2000 years ago) and during the Medieval Warm Period (~1000 years ago) according to the latest peer-reviewed paper. Plus, the long-term trend is down (see below).
Temperature trend for the last 2,000 years (down!). See paper at link immediately above. 
What about the recent heat waves being caused by 'global warming'? Nope. And, that conclusion is reached by my friend meteorologist Dr. Cliff Mass who is a believer that future global warming is a major challenge. Cliff is an excellent scientist even though we disagree as to the potential rate of future warming.

This is an important issue. Here is my recommendation: The heavily politicized IPCC's work is severely flawed. Let's restart the process with excellent scientists on both sides of the issue (the skeptics have been systematically excluded from the IPCC). With better science and less politics we can do a fresh examination of this issue. If, at that point, it appears action needs to be taken it will have significantly enhanced credibility.

The East Coast Severe Weather Threat is Over

Midnight: The East Coast Threat for Tornadoes and Severe  Thunderstorms Has Ended 3:50pm. Tornado watch for the Middle Atlantic Region. 2:30pm Tornadoes are also forecast in the South. 2:20pm. A couple of tornadoes, hail and wind gusts to 65 mph are possible with these storms. This includes NYC and Philadelphia.  1:05pm. The tornado risk has been extended northward into New York. The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

After 65 mph winds went through Wichita, we have been without power for 35 minutes. So, I am going to have to end coverage for the night (using backup systems to write this). Scroll down for the forecast of tornadoes and severe thunderstorms for Sunday and Sunday night.  Please read down for the latest forecasts regarding this dangerous tornado and damaging wind situation! 5:40pm, a new "regular" tornado watch has been issued for north central Kansas.  Note that wind gusts to 80 mph are likely in this storm in addition to tornadoes and giant hail. Please make sure friends and relatives in the area are aware of the danger in the area outlined in red below plus the red area outlined at 2:50pm  In addition to "several strong tornadoes," hail to 4.8" in diameter is forecast along with wind gusts to 80 mph. Now is the time for persons living in mobile homes, manufactured homes and those with mobility issues should be making plans!!  Do not wait until a tornado warn...

Updated Freezing Rain and Heavy Rain Forecast

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue i...
