Patricia Adams is an economist and the executive director of Probe International, a Toronto based NGO that has been involved in the Chinese environmental movement since its beginnings in the mid-1980s.
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 δ18O 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.
A study by the University of Leeds has examined measurements from more than 1600 locations in China and found that more than 50 per cent of the locations showed a significant decrease in concentrations of sulphur dioxide and fine particulates that make up a large portion of air pollution.
The team used datasets from 2015 to 2017 consisting of hourly assessments of concentrations of Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Ozone (O3), and fine particles measuring less than 2.5 μm (PM2.5).

We have to face it: The West has done our planet no favor by moving industrial production and manufacturing to China. Trump is right, many of factories and industries are better back home, even if it means paying a bit more for products.
Not only does the China use the oceans as a global dump for much of its plastic trash, the country now is gearing up to turn parts of the planet into a toxic solar panel waste dump.
According to French science magazine Futura here, we are looking at a “solar panel time bomb”.
Futura describes how China is installing “gigantic” solar panel farms in remote places like Tibet and how 30 years from now the country will have “mountains of solar panels reaching their end of their lives and that nothing is planned for their collection and recycling.”

A prominent feature of all climate model projections is their prediction that temperatures should be rising in response to ever-increasing concentrations of greenhouse gases. However, for the past two decades global surface air temperatures have not warmed to the degree predicted by the models, which lack of warming has been a conundrum to the climate alarmist movement.
China National Petroleum Corp. (CNPC), the largest state-owned producer of oil and natural gas in the country, reportedly plans to nearly double natural gas production from shale sources this year and wants a five-fold increase in such production by 2020.
CNPC said it plans to produce 5.6 billion cubic meters (bcm) (197.8 Bcf) of natural gas from unconventional sources in southwestern Sichuan province in 2018, according to a report Tuesday by Caixin Media Co. Ltd., a Beijing-based news service. The company reportedly plans to drill more than 330 new wells targeting the Sichuan Basin in 2018, and wants to have more than 820 shale gas wells in operation by 2020, with total annual production of 15 bcm (529.7 Bcf). …

China’s carbon emissions growth has accelerated since the beginning of the year, leading to warnings that the country could be headed for its largest annual increase in climate pollution since 2011.
Led by increased demand for coal, oil and gas, China’s CO2 emissions for the first three months of 2018 were 4% higher than they were for the same period in 2017, according to an Unearthed analysis of new government figures.
Analysts have suggested the country’s carbon emissions could rise this year by 5% — the largest annual increase in seven years, back when the airpocalypse was at its peak (…)
Most estimates of Chinese regional Surface Air Temperatures since the late-19th century have identified two relatively warm periods – 1920s–40s and 1990s–present. However, there is considerable debate over how the two periods compare to each other. Some argue the current warm period is much warmer than the earlier warm period. Others argue the earlier warm period was comparable to the present. In this collaborative paper, including authors from both camps, the reasons for this ongoing debate are discussed. Several different estimates of Chinese temperature trends, both new and previously published, are considered. A study of the effects of urbanization bias on Chinese temperature trends was carried out using the new updated version of the Global Historical Climatology Network (GHCN) – version 4 (currently in beta production)

In discussing the characteristics of their three-century temperature proxy, the authors report the existence of two prominent decadal-scale cold periods (1801-1833 and 1961-2003) and two prominent decadal-scale warm periods (1730-1800 and 1928-1960). They also note that “fifteen extreme cold years (< -1.5σ) were identified and most occurred within 1-2 years after major volcanic eruptions,” contrasting with the finding that the two decadal-scale warm periods both occurred during “gaps in volcanic activities.”
Perhaps the most significant observation made by the authors, however, is that “none of the extreme warm years [< 1.5σ] or decades occurred in the most recent 30 years,” which fact runs counter to anthropogenic global warming claims that temperatures of the past few decades have been the warmest of the past thousand years (…)

Coral bleaching is becoming a serious issue for coral reefs under the stress of global warming. However, whether it has occurred in the past in times of thermal stress remains unclear. Moreover, an understanding of historic coral bleaching events would greatly improve our insight into the adaptive capabilities of corals under such stresses. It is known that Porites corals, a massive coral, have relatively high levels of symbiotic zooxanthellae and a strong thermal tolerance when compared with most other corals (and particularly branched corals). Thus, growth hiatuses and/or mortality surfaces of fossil Porites may be used to indicate past ecological or environmental stress events, such as severe bleaching. In this study, monthly geochemical and isotopic environmental proxies of four fossil Porites corals with well‐preserved growth hiatuses and mortality surfaces (aged 3,800–4,200 years before 2013 A.D.), collected from Wenchang fringing reef, Hainan Island, Northern South China Sea were analyzed. Specifically, the Sr/Ca, δ18O, and δ13C were measured with a monthly resolution for each sample.
Scientists at the Chinese Academy of Sciences have put together the first global carbon dioxide maps based on data from the Chinese satellite TanSat. The satellite also measures what lead researcher Yang Dongxu calls “carbon dioxide flux,” changes in its behavior on Earth and in the Earth’s atmosphere.
Beijing has undergone several important urbanization development stages since late 1978. Linked with urbanization, the so-called “urban heat island effect” is a key problem caused by urban land expansion. Such changes in air temperature in Beijing inevitably have an impact on the daily lives of its inhabitants, and is therefore of considerable interest to scientists and the wider public alike.
Dr. Xiaojuan LIU and Associate Professor Guangjin TIAN from the School of Environment, Beijing Normal University, used the mesoscale Weather Research and Forecasting model coupled with a single urban canopy model and high-resolution land cover data to analyze the spatial and temporal patterns of summertime urban warming influenced by three stages of urban land expansion during 1990-2010 across Beijing. They found that urban-induced warming increased with urban land expansion, but the speed of warming declined slightly during 2000-10.

A joint report by Greenpeace, the Sierra Club and CoalSwarm indicates that Southeast Asia will be the new epicentre of coal production. Asia accounts for 85 per cent of new coal power development in the world’s top 20 coal producing countries, with China as the leader of the pack. However, while tighter restrictions on domestic coal plants have been imposed by the central government to curb pollution, Beijing has pushed the development of high-efficiency, low-emission coal plants across Southeast Asia as part of the “Belt and Road Initiative”.
As China is expanding its influence, Beijing’s foremost strategic competitor in Asia, Japan, is being forced to step up efforts to combat its shrinking influence in the region. The booming energy sector of Southeast Asia, especially coal, is proving to be the new front line in the geopolitical rivalry between Asia’s two industrial giants.
Experts say one annual increase doesn’t indicate China is returning to an era when its emissions grew by leaps and bounds. But the increase illustrates the challenges and compromises Beijing must juggle if it wants to stoke its economy and at the same time keep its environmental promises. […]

High-resolution surface temperature records over the last two millennia are crucial to understanding the forcing and response mechanism of Earth’s climate. Here we report a bidecadal-resolution sea surface temperature (SST) record based on long-chain alkenones in a gravity sediment core retrieved from the northern South China Sea. SST values varied between 26.7 and 27.5 °C, with a total variability ∼1 °C over the last 2000 years.
