China’s coal mine methane regulations have not curbed growing emissions
Anthropogenic methane emissions from China are likely greater than in any other country in the world. The largest fraction of China’s anthropogenic emissions is attributable to coal mining, but these emissions may be changing; China enacted a suite of regulations for coal mine methane (CMM) drainage and utilization that came into full effect in 2010. Here, we use methane observations from the GOSAT satellite to evaluate recent trends in total anthropogenic and natural emissions from Asia with a particular focus on China. We find that emissions from China rose by 1.1 ± 0.4 Tg CH4 yr−1 from 2010 to 2015, culminating in total anthropogenic and natural emissions of 61.5 ± 2.7 Tg CH4 in 2015. The observed trend is consistent with pre-2010 trends and is largely attributable to coal mining. These results indicate that China’s CMM regulations have had no discernible impact on the continued increase in Chinese methane emissions.

China has the world’s largest reserves of natural gas but current mining technology makes most of it inaccessible
China is planning to apply the same technology used to detonate a nuclear bomb over Hiroshima during the second world war to access its massive shale gas reserves in Sichuan province. While success would mean a giant leap forward not only for the industry but also Beijing’s energy self-sufficiency ambitions, some observers are concerned about the potential risk of widespread drilling for the fuel in a region known for its devastating earthquakes.
Despite being home to the largest reserves of shale gas on the planet – about 31.6 trillion cubic metres according to 2015 figures from the US Energy Information Administration, or twice as much as the United States and Australia combined – China is the world’s biggest importer of natural gas, with about 40 per cent of its annual requirement coming from overseas.

BEIJING (Reuters) – China’s December coal output climbed 2.1 percent from the year before, government data showed, hitting the highest level in over three years as major miners ramped up production amid robust winter demand and after the country started up new mines.

For all its green talk, China is sticking to fossil fuels
London, 12 December – While leaders of western countries fret about their greenhouse gas emissions in Katowice, China is forging ahead with new projects and investments in coal and gas. According to a new paper from the Global Warming Foundation (GWPF), the Communist Party’s survival depends on delivering economic growth and cleaner air.

China has said it will not approve wind and solar power projects unless they can compete with coal power prices.
Beijing pulled the plug on support for large solar projects, which had been receiving a per kWh payment, in late May. That news came immediately after the country’s largest solar industry event and caught everyone by surprise.
Officials are understood to have been frustrated at seeing Chinese suppliers and engineering firms building solar projects overseas that delivered electricity at prices far below what was available back home.

Trois jours après la clôture de la COP24, l’Agence internationale de l’énergie (AIE) a publié le 18 décembre son rapport annuel consacré au charbon. Elle y souligne le rôle central de cette énergie au niveau mondial et estime que sa consommation globale devrait rester stable dans les 5 prochaines années. Explications.
La consommation de charbon encore appelée à augmenter en Inde et en Asie du Sud-Est
Après deux années de baisse, la consommation mondiale de charbon a augmenté de près de 1% en 2017 et cette hausse devrait se poursuivre en 2018 selon les dernières estimations de l’AIE. Principalement consommé à des fins de production électrique(1), le charbon a encore compté pour 38% de la production mondiale d’électricité en 2017.
Dans son rapport Coal 2018, l’AIE estime que la consommation mondiale de charbon pourrait rester stable d’ici à 2023 : la baisse de la demande envisagée en Europe et en Amérique du Nord serait plus que compensée par une forte croissance de la consommation en Inde et en Asie du Sud-Est selon les prévisions de l’Agence.

- • Japan has strong quasi-20 and quasi-60 years low frequencies sea level fluctuations.
- • These periodicities translate in specific length requirements of tide gauge records.
- • 1894/1906 to present, there is no sea level acceleration in the 5 long-term stations.
- • Those not affected by crustal movement (4 of 5) do not even show a rising trend.
- •Proper consideration of the natural oscillations should inform coastal planning.

Despite being lauded by President Obama for signing the Paris UN Climate Change Accords, China is still rapidly expanding greenhouse gas emissions.
President Obama and China’s President Xi Jinping issued a ‘U.S.-China Joint Presidential Statement on Climate Change’on March 31, 2016 stating that both nations were signing the Paris Accords and would take further “concrete steps” to “use public resources to finance and encourage the transition toward low carbon technologies as a priority.”

Scientists have described a fossil plant species that suggests flowers bloomed in the Early Jurassic, more than 174 million years ago, according to new research in the open-access journal eLife.
Before now, angiosperms (flowering plants) were thought to have a history of no more than 130 million years. The discovery of the novel flower species, which the study authors named Nanjinganthus dendrostyla, throws widely accepted theories of plant evolution into question, by suggesting that they existed around 50 million years earlier. Nanjinganthus also has a variety of ‘unexpected’ characteristics according to almost all of these theories.

She is confirming much of what I have said in recent years. The only thing I would take issue with his her description of there being a U-Turn. In my view, China never had the slightest intention of being serious about cutting emissions.

While there’s little cobalt mining in China itself (1 percent of the world’s total output in 2017), Chinese companies have snapped up cobalt mines abroad in recent years, particularly in the Democratic Republic of Congo, the largest source of the metal.

China produces about two thirds of the whole world’s supply of lithium ion batteries, the most common battery type used in electric vehicles. Furthermore, these highly valuable batteries make up a staggering 40 percent of the cars’ value. As it stands, Europe is far from being able to compete with China when it comes to the production of lithium ion batteries. In fact, currently the entire continent is estimated to hold just 1 percent of the market.

China’s power statistics have now been published for Q3, and continue to show thermal generation rising quickly. (Thermal includes coal, gas and biomass).
The rise in thermal generation since last year is more than from all other sources put together.
Biomass is virtually irrelevant in the overall view of things, having only accounted for 1.2% of generation last year.
Once again, we see that China’s unstoppable demand for energy cannot be supplied from wind and solar alone. Indeed. these two sources have only contributed 18% of the extra year-on-year demand.
In overall terms, wind and solar have only supplied 4.6% and 1.3% respectively of China’s generation so far this year.

The large-scale syntheses of global mean temperatures in IPCC fourth report suggested that the Northern Hemisphere temperature in the second half of the 20th century was likely the highest in at least the past 1,300 years and the 1990s was likely the warmest decade. However, this remains debated and the controversy is centered on whether temperatures during the recent half century were higher than those during the Medieval Climate Anomaly (MCA, AD 800–1300) and the Roman Warm Period (RWP, BC 200–AD 400), the most recent two natural warm periods of the late Holocene. Here the high resolution sea surface temperatures (SSTs) of two time windows around AD 990 (±40) and AD 50 (±40), which located in the MCA and RWP respectively, were reconstructed by the Sr/Ca ratio and δ 18O of Tradacna gigas shells from the northern South China Sea. The results suggested that the mean SSTs around AD 990 (±40) and AD 50 (±40) were 28.1 °C and 28.7 °C, 0.8 °C and 1.4 °C higher than that during AD 1994–2005, respectively. These records, together with the tree ring, lake sediment and literature records from the eastern China and northwest China, imply that the temperatures in recent decades do not seem to exceed the natural changes in MCA, at least in eastern Asia from northwest China to northern SCS.
