Oxygen-18 Stability in Foraminifera fossils, implications in paleoclimatology

by Andy May, November 4, 2017


18O is a rare isotope of oxygen. The ratio of 18O to the normal 16O in foraminifera fossils (“forams”) can be used to estimate paleo-ocean temperatures. Higher values mean lower temperatures. A recent article on geologypage.com (here) led me to Bernard, et al., 2017, which has experimental data that suggest 18O concentrations can be altered in fossils by solid-state diffusion after fossilization. This can corrupt the measurement and the resulting calculated temperature

What You Won’t Find in the New National Climate Assessment

by Dr Pat Michaels, November 3, 2017 in WUWT


Under the U.S. Global Change Research Act of 1990, the federal government has been charged with producing large National Climate Assessments (NCA), and today the most recent iteration has arrived. It is typical of these sorts of documents–much about how the future of mankind is doomed to suffer through increasingly erratic weather and other tribulations. It’s also missing a few tidbits of information that convincingly argue that everything in it with regard to upcoming 21st century climate needs to be taken with a mountain of salt.

 

Analysis Of European Sea Level Rise

by Paul Homewood, November 2, 2017 in NotLotPeopleKnowThat


European mean sea-level records are among the best time series data available globally by which to detect the presence of necessary accelerations forecast by physics-based projection models to elevate current rates of global sea-level rise (≈3 mm/y) to anywhere in the vicinity of 10–20 mm/y by 2100. The analysis in this paper is based on a recently developed analytical package titled “msltrend,” specifically designed to enhance estimates of trend, real-time velocity, and acceleration in the relative mean sea-level signal derived from long annual average ocean water level time series

Acceleration in European Mean Sea Level? A New Insight Using Improved Tools

by Phil J. Watson, October 21, 2016 in J. of Coastal Research


(…)Key findings are that at the 95% confidence level, no consistent or compelling evidence (yet) exists that recent rates of rise are higher or abnormal in the context of the historical records available across Europe, nor is there any evidence that geocentric rates of rise are above the global average. It is likely a further 20 years of data will distinguish whether recent increases are evidence of the onset of climate change–induced acceleration.

Again And Again: Experts And New Findings Show No Link Between European Storm Activity And CO2

by P. Gosselin, October 31, 2017 in NoTricksZone


By Dr. Sebastian Lüning and Prof. Fritz Vahrenholt
(German text translated/edited by P. Gosselin)

This month two major North Sea storms have hit Europe rather severely, and not surprisingly the usual climate ambulance chasers were out in force to try to pin the blame on man’s activity, and in doing so ignored the climate history that provides us with the proper perspective. We look at some analyses of past German storm activity.

Température des océans: la fiabilité des calculs remise en cause

by Le Vif, 31 octobre 2017


Les scientifiques en déduisent que le réchauffement global actuel pourrait potentiellement être “sans précédent” sur les 100 derniers millions d’années. L’étude de ces géochimistes, publiée dans Nature Communications, constitue une sorte de pavé dans la mare des paléoclimatologues qui utilisent depuis les années 1950 ce “paléothermomètre” aidant à bâtir les modèles actuels sur le réchauffement climatique

Retrograde Accretion of a Caribbean Fringing Reef Controlled by Hurricanes and Sea-level Rise

by P. Blanchon et al., October 12, 2017 in Front.Earth.Sci


Predicting the impact of sea-level (SL) rise on coral reefs requires reliable models of reef accretion. Most assume that accretion results from vertical growth of coralgal framework, but recent studies show that reefs exposed to hurricanes consist of layers of coral gravel rather than in-place corals. New models are therefore needed to account for hurricane impact on reef accretion over geological timescales

Some Failed Climate Predictions

by Javier, October 30, 2017 in WUWT


Here, for the first time in public, is Javier’s entire collection of massive, “consensus” climate science prediction failures. This collection is carefully selected from only academics or high-ranking officials, as reported in the press or scientific journals. Rather than being exhaustive, this is a list of fully referenced arguments that shows that consensus climate science usually gets things wrong, and thus their predictions cannot be trusted.

Rapid Growth of Arctic Sea Ice Persists Thru Last Half of October

by Ron Clutz, October 30, 2017 in ClimateChangeDispatch


Extents expanded rapidly during the last 12 days of October through yesterday, especially on the Eurasian side. At the top center the Laptev Sea fills in completely, and to the left East Siberian Sea is also growing solid ice toward East Asia. Kara sea on the right is growing fast ice from the shore outward, while the Barents Sea fills in from the central Arctic.

An Informative Interview with István Markó

by Istvan Marko (1956-2017), October 28, 2017 in WUWT


This interview was published by Breitbart News Network, in an edited version, on 28 October 2017. Here is the complete version.

István Markó (1956 – 2017) was a professor and researcher in organic chemistry at the Université catholique de Louvain. Prof. Dr. Marko was an outspoken defender of the skeptical view on the issue of human-caused/anthropogenic global warming, appearing in numerous French-language media on the Internet, in public debates and diverse English-language blog postings. He also joined with Anglo-Saxon climate skeptics, publishing several articles together on Breitbart News.

IEA sees Southeast Asia oil demand growing until at least 2040

by Florence Tan, October 26, 2017 in Reuters


SINGAPORE (Reuters) – Southeast Asian demand for oil will keep growing until at least 2040 as emerging nations there rely on the fossil fuel to transport their rapidly growing populations, ship goods and make plastics, the International Energy Agency said on Tuesday.

Oil usage in the region will expand to around 6.6 million barrels per day by 2040 from 4.7 million bpd now, with the number of road vehicles increasing by two-thirds to around 62 million, the agency said in a report. It did not make any forecasts beyond 2040.

Al Gore’s Apocalyptic Fantasy Lecture at Rice University

by Andy May, October 24, 2017 in WUWT


As promised, I attended Al Gore’s climate change lecture at Rice University last night. Rice University is one of the most beautiful university campuses I’ve ever seen, so it was a delight to see it again. The architecture is outstanding, and the buildings are placed in a garden-like setting. It was lovely to walk from the parking lot to the fieldhouse. The speech was held in a packed Tudor Fieldhouse which seats 5,750. By the time the Rice University Provost was introducing Al Gore, there were no empty seats that I could see, see Figure 1.
