This paper addresses the Solar Activity cause and effect of climate change and their various impacts. Earth’s climate is determined by complex interactions among the Sun, oceans, atmosphere, cryosphere, land surface and biosphere. The Sun is the principal driving force for Earth’s weather and climate. The Sun’s energy is distributed unevenly on Earth’s surface due to the tilt of Earth’s axis of rotation. Over the course of a year, the angle of rotation results in equatorial areas receiving more solar energy than those near the poles. As a result, the tropical oceans and land masses absorb a great deal more heat than the other regions of Earth. The atmosphere and oceans act together to redistribute this heat. As the equatorial waters warm air near the ocean surface, it expands, rises and drifts towards the poles; cooler denser air from the subtropics and the poles moves toward the equator to take its place. This continual redistribution of heat is modified by the planet’s west to east rotation and the Coriolis force associated with the planet’s spherical shape, giving rise to the high jet streams and the prevailing westerly trade winds. The winds, in turn, along with Earth’s rotation, drive large ocean currents such as the Gulf Stream in the North Atlantic, the Humboldt Current in the South Pacific, and the North and South Equatorial Currents. Ocean currents redistribute warmers waters away from the tropics towards the poles. The ocean and atmosphere exchange heat and water, carbon dioxide and other gases. By its mass and high heat capacity, the ocean moderates climate change from season to season and year to year. These complex, changing atmospheric and oceanic patterns help determine Earth’s weather and climate. Scientists all over the world are making predictions about the ill effects of Global warming and connecting events. The effect of global warming is increasing the average temperature of the Earth. A rise in Earth’s temperatures can in turn root to other alterations in the ecology, including an increasing sea level and modifying the quantity and pattern of rainfall. These modifications may boost the occurrence and concentration of severe climate events, such as floods, famines, heat waves, tornados, and twisters. Other consequences may comprise of higher or lower agricultural outputs, glacier melting, lesser summer stream flows, genus extinctions and rise in the ranges of disease vectors. As an effect of global warming species like golden toad, harlequin frog of Costa Rica has already become extinct. There are number of species that have a threat of disappearing soon as an effect of global warming. As an effect of global warming various new diseases have emerged lately. These diseases are occurring frequently due to the increase in Earths average temperature since the bacteria can survive better in elevated temperatures and even multiply faster when the conditions are favorable. The global warming is extending the distribution of mosquitoes due to the increase in humidity levels and their frequent growth in warmer atmosphere. Various diseases due to ebola, hanta and machupo virus are expected due to warmer climates. The marine life is also very sensitive to the increase in temperatures. The effect of global warming will definitely be seen on some species in the water. A survey was made in which the marine life reacted significantly to the changes in water temperatures. It is expected that many species will die off or become extinct due to the increase in the temperatures of the water, whereas various other species, which prefer warmer waters, will increase tremendously. Perhaps the most disturbing changes are expected in the coral reefs that are expected to die off as an effect of global warming. The global warming is expected to cause irreversible changes in the ecosystem and the behavior of animals

This paper addresses the cause and effect of climate change and their various impacts. Earth's climate is determined by complex interactions among the Sun, oceans, atmosphere, cryosphere, land surface and biosphere. The Sun is the principal driving force for Earth's weather and climate. The Sun's energy is distributed unevenly on Earth's surface due to the tilt of Earth's axis of rotation.

As a result, the tropical oceans and land masses absorb a great deal more heat than the other regions of Earth. The atmosphere and oceans act together to redistribute this heat.

The effects of global climate warming on plant-pollinator networks have attracted extensive attention at present. In this paper, we attempt to introduce several major advances and some new interests in this area. Furthermore, we discussed the future research trends of plant-pollinator networks based on continuously rising temperature. (1) Climate warming makes phenology shift of plants and pollinators by affecting flowering time of plants and activity time of pollinators, which leads to a temporal decoupling of plants and pollinators. (2) Climate warming may cause changes in community structure of plants and pollinators and thus make them distribute to areas in higher latitude and altitude. These changes may result in spatial mismatch of plants and pollinators. (3) Plants and pollinators response to climate warming by increase or decrease its abundance, which may cause changes in structure of pollination networks. (4) The structure and rapid evolution of pollination networks can adapt to the changes or even collapse of interaction between plants and pollinators that result from the phenological and geographical distribution mismatch caused by climate warming. The following contents should be studied in the further research: (1) The effects of climate warming on plant-pollinator networks at large spatiotemporal scales; (2) The effects of multi-factorial synergy on plant-pollinator networks; (3) The mechanism of phenological matching caused by global warming. 参考文献 相似文献 引证文献

American fall webworm in China: A new case of global biological invasions

The purpose of this study was to investigate the mechanism of adsorption reaction between heterocyclic organic compounds with different number of ring atoms and different atoms replacing carbon atoms and carbon nanotubes with different surface functional groups. Based on the current situation of research on adsorption of carbon nanomaterials adsorbing organic pollutants, the existing problems and limitations were analyzed by studying the properties and characterization of single-walled carbon nanotubes, oxidized single-walled carbon nanotubes and non-porous graphite powder, such as elemental analysis, transmission electron micrograph, zero charge point, etc. The three adsorption materials were investigated by batch experiment. Six compounds of thiophene, pyrimidine, benzene, aniline, 2-aminopyrimidine and 4,6-diaminopyrimidine were selected as the adsorbate for detecting adsorption capacity. The results showed that the affinity of different adsorbents on different adsorbents varied greatly. The adsorption capacity of heterocyclic compounds containing N and S was greatly enhanced by non-hydrophobic action. And the degree of oxidation of the adsorbent and the ph of the solution determined the adsorption capacity of the adsorbent for nitrogen-containing heterocyclic compounds. Therefore, in the ecological environment, the migration of hydrophilic organic pollutants in the environment can be reduced by the preparation of appropriate carbon nanotubes.

The objective of the research was to identify recent studies which have shown that previous climate changes are not comparable to the current global warming. The magnitude of these changes we all feel nowadays, and the effects most of the time with significant damage to both people and the environment, have reached a significant increase. It is well known that the rural environment is the area where food is produced, and that is why it is necessary not to postpone at all, the protective measures against the effects of global warming. Protecting air, water and soil resources against pollution and degradation must be the number one priority for sustainable rural development. The study area, namely Aghiresu area, is located in Cluj County, Transylvania, Romania, and it is known for its preponderant activity in agriculture and mining. It brings into attention, the situation of several limestone fields where the groundwater is strongly affected by the underground galleries. The principles of sustainable development especially of the rural environment, now more than ever, must take into account the quality of life, which depends on the protection of the environment and the existing resources.

Effects of meteorological factors and global warming on rice insect pests in Korea

Coral reefs have been threatened for ≥35 years, primarily by global warming, disease, and unwanted inter-oceanic species introductions. Here we discuss differences between the evolution of corals and other organisms in the Atlantic vs. the Pacific Oceans through natural selection caused by oceanic cooling in the Atlantic and the resultant differential extinctions. We will also consider the implications of differential Pacific vs. Atlantic adaptations for invasive species and how it makes the former formidable predators and competitors. The effects of climate change and global warming on corals will also be considered, including the poleward movement of our current climatic zones at the expense of the polar and sub-polar zones. We also predict the creation of a new “Hyper-Tropical Zone” in the center of the Equatorial Zone, characterized by mass mortalities of zooxanthellate organisms, causing both local endemic and global pandemic extinctions. The effects of global warming on the coral-zooxanthellar symbiotic relationship examines how zooxanthellae may be the “weak” link in the system, explaining why they are having difficulty keeping up with the pace of global warming. We also consider the possibility of a replacement symbiont arising. In this context, we examine the evolution of coral immunity as it affects the host, symbiont replacement, and disease. Such studies will help us to better understand the evolution of innate and adaptive immune systems, and ultimately better understand vertebrate model systems for human health studies.

Lyngby, Denmark 2Danish Meteorological Institute, 2100 Copenhagen Ø, Denmark *Corresponding author: mard@dtu.dk ABSTRACT: In this Climate Research (CR) Special, the Centre for Regional Change in the Earth System (CRES) brings together scientific expertise (ranging from climate to social sciences) with practitioners and stakeholders to present thematic research addressing gaps in (1) our understanding of climate-system behaviour at a regional scale and in particular at the upper fringes of current climate scenarios; (2) what the effects of such changes might be; and (3) potential adaptations. CRES has developed a broad set of tools related to climate adaptation; this includes improved regional climate and hydrological models, impact models, integrated assessment models, economic models, decision support tools and spatial planning tools. Through a coordinated research effort these tools were applied to provide new information on climate, hydrology, nutrient dynamics, ecosystem responses and economic risks. The studies in this CR Special highlight potential effects of extreme global warming with a focus on Denmark and northern Europe.
