Abstract Silicate rock weathering maintains a stable and long‐term absorption of CO 2 . However, the magnitude, spatial pattern, evolution characteristics global silicate carbon sink (SCS) remain unclear. To solve this problem, based on high‐precision hydrometeorological data (1996–2017) CMIP5 (2041–2060), using Celine model, we calculated flux (SCSF) magnitude spatio‐temporal distribution for 1996–2017. We also predicted SCSF under two future greenhouse gas emission scenarios (RCP 4.5 RCP...
The accurate determination of the carbon-neutrality capacity (CNC) a region is crucial for developing policies related to emissions and climate change. However, systematic diagnostic method determining CNC that considers rock chemical weathering carbon sink (RCS) lacking. Moreover, it challenging but indispensable establish fast practical index model determine CNC. Here, we selected Guizhou as study area, used methods different types sinks, constructed (CNCI) model. We found that: (1)...
Abstract The Carbonate rock weathering Carbon Sink (CCS) and Silicate (SCS) play a significant role in the carbon cycle global climate change. However, spatial‐temporal patterns trends of CCS SCS from 1950 to 2099 have not been systematically quantified. Thus, Supported by long‐term hydrometeorological data under RCP8.5, we use accepted Suchet Hartmann models determine following. First, found except for difference their rates, covers 37.2 million km 2 more area than CCS. Flux (CCSF) (SCSF)...
Climatic and non-climatic factors affect the chemical weathering of silicate rocks, which in turn affects CO2 concentration atmosphere on a long-term scale. However, coupling effects these prevent us from clearly understanding global carbon sink rocks. Here, using improved first-order model with correlated non-parametric methods, we produced spatiotemporal data sets (0.25° × 0.25°) carbon-sink flux (SCSFα ) under different scenarios (SSPs) present (1950-2014) future (2015-2100) periods based...
Cropland area has long been used as a key indicator of food security. However, grain yield is not solely controlled by the cropland. Therefore, we proposed new to assess Results show that from 1992 2004, global cropland increased 840 200 km2 (99.4%), but only 310 million t (29.1%); and 2004 2015, decreased 39 000 (4.64%), 370 (70.84%). This result showed was linearly correlated with area, delimiting threshold protection may guarantee Combined further correlation analysis, found increase in...
Ferroelectric flux-closures are very promising in high-density storage and other nanoscale electronic devices. To make the data bits addressable, required to be periodic via a controlled growth. Although flux-closure quadrant arrays with 180° domain walls perpendicular interfaces (V-closure) have been observed strained ferroelectric PbTiO3 films, quadrants therein rather asymmetric. In this work, we report not only array of symmetric parallel (H-closure) but also large scale alternative...
In recent decades, China has exhibited the fastest and most remarkable social-economic development in world. As a result of such development, forest cover country undergone radical changes. This paper aims to develop method for analyzing long-term spatial changes based on historical maps remote sensing images. Moreover, we will focus reduction or restoration forests distributed at different altitudes, slopes, soils, lithologic types periods, reveal problems that should be paid attention...
Identifying the impacts of climatic factors on runoff change has become a central topic in climate and hydrology research. This issue, however, received minimal attention karst watersheds worldwide. Multi-resolution analysis (MRA), continuous wavelet transform (CWT), cross (XWT) coherence (WTC) are used to study teleconnection time frequency between hydrological processes typical watershed at different scales. The main results are: (1) All exhibit cycle 12-month scales with changes, but...
Extrapallial fluid (EPF) is located between the shell and mantle, it believed to play key roles in biomineralization Pinctada fucata. However, few studies have been performed on effect of EPF. In this work, CaCO3 crystallization experiments showed that EPF proteins could not only control morphology but also regulate phase transition calcium carbonate through different specific binding calcite or aragonite. crystal growth inhibition experiments, when final concentration CaCl2 NaHCO3 reduced...
Introduction Accurate assessment of the net ecosystem productivity (NEP) is very important for understanding global carbon balance. However, it remains unknown whether climate change (CC) promoted or weakened impact human activities (HA) on NEP from 1983 to 2018. Methods Here, we quantified contribution CC and HA under six different scenarios based a boosted regression tree model sensitivity analysis over last 40 years. Results discussion The results show that (1) total 69% areas showed an...
