It turned out that the age of Ellesmere Island ice shelves is estimated by driftwood located on the shore. an age of ~3,000 years is estimated for the Ward Hunt ice shelf (in which a crack recently developed) based on driftwood located onshore. I haven’t seen corresponding information on the Ayles ice shelf (which actually […]
The following is from Judith Curry: Whether changes in the characteristics of tropical storms observed in the last few decades [1,2] are the result of only natural variability, due to climate change, or a combination of both factors is the subject of intense debate [3]. Central to the debate is the quality of the tropical […]
The break-up of (Ward Hunt and Ayles) ice shelves on the north shore of Ellesmere island gets in the news from time to time (google “Ward Hunt ice shelf”) and has been mentioned by posters here. The issue as framed by Steve Bloom is: However, if [the Ward Hunt Ice Shelf] is ~3000 year old […]
Perhaps the key issue in Emanuel 2005 (as observed in Landsea’s 2005 comment) was the adjustment to the ATL data set performed by Emanuel (citing an old publication, Landsea 1993). We’ve snickered a bit recently at Martin Juckes using older data rather than newer data – only in climate science would this seem possible. And […]
A comment by Judith Curry reminded of a suggestion that Ross McKitrick sent me for a CA contest. Judith said: There is no fear of H/W making it into IPCC4, the closing for papers to be accepted was over a year ago. What Judith said here is what IPCC rules said prior to IPCC AR4. […]
OK folks, here’s a question – no peeking. In terms of the total number of hurricane-days (i.e. days at wind-speed gt 65 knots) west of 69W, where does 2005 rank in the league table including all years since 1851? Bonus points if you get the top five right regardless of order.
Despite the protestations of the Team, it seems to be a consensus of other paleoclimatologists that the Holocene Optimum was warmer at high southern latitudes. For now, I’ll take this as read, although it’s well worth canvassing the literature. Some citations are at ukweatherworld. The next line of Team attack on the Holocene Optimum is […]
Examining the ATL hurricane data in another thread, I pointed out that there was a very substantial increase in coverage further to the east. In the entire data set, the median westing for a track measurement was 69W. To attempt to minimize count bias resulting from increased eastward coverage, I did storm and hurricane count […]
Since Hansen’s article in September, we’re starting to hear the phrase “warmest in 12000 years”- google “warmest 12000 years” and you’ll see recent coverage. This immediately raises the question of the Holocene Optimum – a period from about 8000 to 5200 BP in which there is undisputed evidence of significant NH warmth. The Team has […]
