Stronger oil and natural gas prices combined with continuing development of shales and low permeability formations drove producers of crude oil and natural gas in the United States to report new all-time record levels of proved reserves for both fuels in 2017. Total U.S. oil reserves in 2017 exceeded a brief, one-year, 47-year-old record, highlighting the importance of crude oil development in shales and low permeability plays, mainly in the Southwest. The new record for natural gas extends a longer-term trend of development, mainly in shale plays in the Northeast. Both U.S. proved reserves of crude oil and natural gas are approximately double their levels from a decade ago. These new proved reserves records were established in 2017 despite production of crude oil at levels not seen since 1972, and record natural gas production.
Highlights are listed below.

The unexpected results of a 20-year study into reef fisheries published in the journal Nature Ecology and Evolution this week showed fisheries being maintained despite extreme coral bleaching. Remarkably, rapid proliferation of fishes with low dependence on corals led to catches remaining stable or even increasing.
But the results also showed fishing success was ‘patchy’ and more dependent on fewer species.
Around six million people fish on coral reefs. Each year their catch — estimated to be between 1.4 and 4.2 million tonnes — provides a critical source of food and income for many millions more.

Here, we reconstructed Phanerozoic PCO2 from a single proxy: the stable carbon isotopic fractionation associated with photosynthesis (Ɛp) that increases as PCO2 increases. This concept has been widely applied to alkenones, but here, we expand this concept both spatially and temporally by applying it to all marine phytoplankton via a diagenetic product of chlorophyll, phytane. We obtained data from 306 marine sediments and oils, which showed that Ɛp ranges from 11 to 24‰, agreeing with the observed range of maximum fractionation of Rubisco (i.e., 25 to 28‰). The observed secular PCO2 trend derived from phytane-based Ɛp mirrors the available compilations of PCO2over the past 420 Ma, except for two periods in which our higher estimates agree with the warm climate during those time periods. Our record currently provides the longest secular trend in PCO2 based on a single marine proxy, covering the past 500 Ma of Earth history

After decades of alarm calls over the impact of human emissions of carbon dioxide (CO2) on global temperatures and climate change, a glaring lack of factually demonstrated and scientifically proven evidence remains.
The evidence presented has been based on computer modeling of temperatures from global weather stations, a larger percentage of which are sited in towns and cities and no data, numerous studies show.
For the 70% of oceans, seas, and lakes, satellite measurements are routinely adjusted to take account of anomalies and sea level rise alarm, expressed in measurements of millimeters per century, does not quantify in that tidal gauges are subjected to landmass upheavals and/or subsidence, none of which can be taken to represent empirical evidence.

I have now completed my assessment of sea level rise and climate change.
The complete report can be downloaded here [Special Report- Sea Level Rise ].
My preliminary compilation of information was provided in the 7 part Climate Etc. series Sea level rise acceleration (or not).
This report reflects 18 months of work on this topic. Why have I devoted so much time to the sea level rise issue? First, I regard sea level rise to be the most consequential potential impact of predicted global warming. Second, there is a great deal of public confusion about the issue, including decision makers. Third, a number of CFAN’s clients have queried me about a range of specific concerns that they have regarding sea level rise (and I have been doing consulting on this topic).
Why do I think an independent assessment of the sea level rise issue by yours truly is needed, given the plethora of international and national assessment reports? My clients are concerned about the alarmist predictions they have encountered. I have seen various ‘experts’ make public statements projecting 21stcentury sea level to be as high as 9 m [30 feet]. My clients are looking for someone that they trust to provide an objective assessment that focuses on their issues of concern.

The levels of oxygen dramatically rose in the atmosphere around 2.4 billion years ago, but why it happened then has been debated. Some scientists think that 2.4 billion years ago is when organisms called cyanobacteria first evolved, which could perform oxygen-producing (oxygenic) photosynthesis.
Other scientist think that cyanobacteria evolved long before 2.4 billion years ago but something prevented oxygen from accumulating in the air.
Cyanobacteria perform a relatively sophisticated form of oxygenic photosynthesis — the same type of photosynthesis that all plants do today. It has therefore been suggested that simpler forms of oxygenic photosynthesis could have existed earlier, before cyanobacteria, leading to low levels of oxygen being available to life.
Now, a research team led by Imperial College London have found that oxygenic photosynthesis arose at least one billion years before cyanobacteria evolved. Their results, published in the journal Geobiology, show that oxygenic photosynthesis could have evolved very early in Earth’s 4.5-billion-year history.

And What Have the Average Temperatures of Earth’s Surfaces Been Recently in Absolute Terms, Not Anomalies?
The answers may surprise you.
THIS POST HAS BEEN UPDATED. The update is near the end of the post.
So, for the purpose of this very simple illustration and comparison, and for the discussions it will generate, I’ve added 14 deg C to the annual GISS LOTI data available here, and added 14.186 deg C to the annual Berkeley Earth data. I also compared them to the 12.04 deg C to 15.05 deg C range of hindcast preindustrial global mean surface temperatures from the climate model ensemble members discussed earlier. See Figure 3. Not too surprisingly, the Berkeley Earth and GISS global mean surface temperatures, in absolute form, are very similar, with only a 0.1 deg C difference during the most recent 30-years.

Winter has arrived much earlier than normal this year, particularly across North America, where cold records have been shattered.
This Thanksgiving is in fact going down as one of the coldest ever on record across the Northeast. The Washington Post here, for example, reports that Thanksgiving and Black Friday 2018 will be remembered for a record-shattering cold snap across the Northeast United States.”
Arctic sea ice, snow and ice cover rebound
Arctic sea ice volume has rebounded and is near normal levels. The sea ice trend has remained stable over the past decade and thus defy all the climate alarmist predictions of an Arctic meltdown.

Newly published macrofossil discoveries from 4 papers strongly suggest that modern warmth may still be about 3°C colder than nearly all of the last 10,000 years.
by Mo Mozuch, November 22, 2018 in Newsweek
Talk about cold turkey! The coldest Thanksgiving in 100 years, and quite possibly the coldest Thanksgiving ever, has hit the Northeast United States today.
The unprecedented cold snap comes courtesy of a large Canadian chill working its way across the country on its way to the Atlantic. According to the Weather Network, the deep freeze is the result of a large, low pressure system moving south from the Arctic across the Great Lakes. Combine that with a wicked wind chill, and many Americans are looking at the coldest Thanksgiving in a century.

La raison d’être de la taxe carbone qui pèse sur les carburants est qu’en augmentant le prix des carburants en France, cette taxe va diminuer la consommation de carburant, et les rejets de CO2 qui vont avec. Le raisonnement est solide. Mais la question est : de combien ? C’est l’enjeu. L’augmentation de cette taxe met le pays à feu et à sang. C’est la chandelle. Le jeu en vaut-il bien la chandelle ?
Pour y répondre il faut connaître la sensibilité de la consommation au prix, ce qu’on appelle l’élasticité-prix. C’est le rapport de l’effet, la variation de consommation (mesurée en %) sur la cause, la hausse de prix (également mesurée en %). Si une hausse des prix de 10% entraîne une diminution de consommation de 8%, l’élasticité est de -0,8.

Fossil fuels helped humanity improve our health, living standards and longevity in just 200 years.
Then, suddenly, a great miracle happened! Beginning around 1800, health, prosperity and life expectancy began to climb … slowly but inexorably at first, then more rapidly and dramatically. Today, the average American lives longer, healthier and better than even royalty did a mere century ago.
How did this happen? What was suddenly present that had been absent before, to cause this incredible transformation?
Humanity already possessed the basic scientific method (1250), printing press (1450), corporation (1600) and early steam engine (1770). So what inventions, discoveries and practices arrived after 1800, to propel us forward over this short time span?

HE LONGEST, DEEPEST UNDERWATER GAS NETWORK IN THE WORLD
Greece, Italy, and Cyprus have reached an agreement with Israel to lay a pipeline connecting the Jewish state’s gas reserves to the three countries, in a major project estimated at costing over $7 billion that will supply gas from the eastern Mediterranean to Europe, as the continent seeks to diversify its energy supply.
According to Hadashot TV, the European Union agreed to invest $100 million in a feasibility study for the project before the agreement was reached over the laying of the longest and deepest underwater gas pipeline in the world.

Indonesia’s consumption of domestic coal for power generation will almost double from 84 million t in 2018 to 157 million t by 2027. This increases power generation’s share of domestic consumption from 18.5% to 33.6%, which is likely to displace export tonnage.
Another factor contributing to the higher coal consumption is that Indonesia’s new power plants are designed to consume lower energy coal. This means more coal will be required per unit of electricity generated.
This increase in domestic consumption combined with potential government efforts to conserve coal reserves represents a downside risk for Indonesian exports.

Chapter 6 – Temperature Changes in the United States of the U.S. Global Change Research Program’s recently published Climate Science Special Report (2017) clearly shows and discusses, under the heading of “6.1.2 Temperature Extremes”, how temperature extremes for the contiguous United States have become more moderate over the last 118 years, with the coldest daily temperatures warming and the warmest daily temperatures cooling. In other words, temperature-extreme-related climate in the United States has improved.
