Climate change and global warming

摘要

Climate change and its directly significant effect, i.e., global warming, have recently become more and more remarkable global problems. Global atmospheric concentrations of CO2, CH4 and N2O have increased markedly as a result of human activities since 1750, thus the Earth's climate must change somehow to restore the balance between incoming and outgoing radiation. Under the effect of global warming, sea level will rise, which will cause potential impacts on human life. People must find new styles to develop the economy by using clean energy, making new emission standards, increase producer responsibility for pollution, etc. Natural events and human activities are believed to be contributing to an increase in average global temperatures. In this issue, some important websites were concentrated on to provide the readers with more convenient, comprehensive and informative resources related to climate change and global warming.
