“…The decreases in CPM concentrations could be caused mainly by hydrophilic effect related to relative humidity and the changes in dry and wet depositions related to cloud cover, precipitation, and wind. The simulated results show that changes in column concentrations of smaller particles are less sensitive to climate feedback and more dependent on their source emissions, whereas larger particles are more susceptible to climate feedback (Yang et al ., 2019).…”

In order to quantify air pollution effects on climate change, we investigated the climate response associated with anthropogenic particulate matters (PMs) by dividing fine PM (PM 2.5 , particle size ≤2.5 μm) and coarse particulate matter (CPM, particle size >2.5 μm) in great detail in this work, with an aerosol-climate coupled model. We find that the changes in PM 2.5 and CPM are very different and thus result in different, even opposite effects on climate, especially on a regional scale.The column burden of PM 2.5 increases globally from 1850 to the present, especially over Asia's southern and eastern parts, whereas the column concentration of CPM increases over high-latitude regions and decreases over South Asia. The resulted global annual mean effective radiative forcing (ERF) values due to PM 2.5 and CPM changes are −1.21 WÁm −2 and −0.24 WÁm −2 , respectively. Increases in PM 2.5 result in significant cooling effects on the climate, whereas changes in CPM produce small and even opposite effects. The global annual mean surface air temperature (SAT) decreases by 0.94 K due to PM 2.5 increase. Coolings caused by increased PM 2.5 are more apparent over Northern Hemisphere (NH) terrain and ocean at mid-and high latitudes. Increases in SATs caused by increased CPM are identified over high latitudes in the NH, whereas decreases are identified over mid-latitude regions. Strong cooling due to increased PM 2.5 causes a southward shift of the Intertropical Convergence Zone (ITCZ), whereas the Hadley circulation associated with CPM is enhanced slightly over both hemispheres, along with the weak movement of corresponding ITCZ. The global annual mean precipitation decreases by approximately 0.11 mm day −1 due to the increased PM 2.5 . Generally, PM 2.5 concentration changes contribute more than 80% of the variation caused by all anthropogenic aerosols in ERF, SAT, cloud fraction, and precipitation.

“…PM 2.5 and CO 2 are the primary substances that cause global warming. PM 2.5 changes the net photosynthetic rate by affecting plant photosynthesis, thereby affecting ecosystem NPP [ 15 , 16 , 17 , 18 ]. NPP is an essential variable to characterize plant activities and a crucial factor in determining ecosystem carbon sinks and regulating ecological processes [ 19 ].…”

With global warming, the concentrations of fine particulate matter (PM2.5) and greenhouse gases, such as CO2, are increasing. However, it is still unknown whether these increases will affect vegetation productivity. Exploring the impacts of global warming on net primary productivity (NPP) will help us understand how ecosystem function responds to climate change in China. Using the Carnegie-Ames-Stanford Approach (CASA) ecosystem model based on remote sensing, we investigated the spatiotemporal changes in NPP across 1137 sites in China from 2001 to 2017. Our results revealed that: (1) Mean Annual Temperature (MAT) and Mean Annual Precipitation (MAP) were significantly positively correlated with NPP (p < 0.01), while PM2.5 concentration and CO2 emissions were significantly negatively correlated with NPP (p < 0.01). (2) The positive correlation between temperature, rainfall and NPP gradually weakened over time, while the negative correlation between PM2.5 concentration, CO2 emissions and NPP gradually strengthened over time. (3) High levels of PM2.5 concentration and CO2 emissions had negative effects on NPP, while high levels of MAT and MAP had positive effects on NPP.

“…The concentrations of three greenhouse gases, carbon dioxide, methane, and nitrous oxide (N 2 O), were in the last decade higher than those recorded for at least 800,000 years [8]. The continuous rise of these greenhouse gases creates a potential risk of breaching climate tipping points with devasting consequences, such as the collapse of ice sheets, abrupt changes in ocean circulation [9], complex extreme weather events [10], and far greater global warming than projected [11]. The long-term storage of carbon dioxide, which is the most-produced greenhouse gas (about 80%) emitted into the atmosphere by human activities [12], could be the solution for these effects.…”

Review of the Monitoring Applications Involved in the Underground Storage of Natural Gas and CO2

Natural gas is an indispensable resource not evenly distributed in the world. The gas supply chain is characterized by large imbalances between supply and demand, where the underground gas storage (UGS) application plays a key role for creating strategic reserves, taking advantage of geological structures. On the contrary, human activities will require clean energy with near-zero greenhouse gas emissions to be environmentally viable. A key element of this strategy is the carbon capture and storage (CCS) application useful for confining CO2 into the geosphere to reduce anthropogenic emissions. The development of appropriate injection methods and long-term monitoring systems for leak detection of the underground storage of natural gas and CO2 is important to prevent negative effects, such as ground deformations and micro seismic events. In this work, a variety of monitoring applications were gathered and critically analyzed for a total of 60 scientific contributions spanning the world. This bibliographic work shows an analytical and statistical overview of the most common use of UGS and CCS, representing the different goals of these two applications and analyzing the main monitoring techniques used in the gathered contributions. Currently, UGS monitoring requires further development, especially through multidisciplinary approaches useful for identifying possible effects on the surface and gas leaks at depth; meanwhile, CCS solutions are still at the experimental stage, also because of the high costs for large-scale applications that still need specific research. The state of the art of these two very different practices can improve the further development of new monitoring approaches or additional methods.
