Climate Change and Global Warming

However, the levels of these contaminants in the environment, especially that of COj and methane emissions from hnman activity, have steadily increased by about 40%, from 280 ppm, at the time of industrial revolution, to about 337 ppm today (see Eig. 1.11). Higher levels of CO have not been seen in Earth s atmosphere for nearly

Because of the concern about climate change and global warming, it is important to have reliable data on the trends in various areas of the planet. Weather stations monitor the following variables over the noted typical ranges (for the errors in these measurements, refer to Table 3.179) ... 

Carbon Dioxide Removal (CDR) Geoengineering techniques and technologies that remove carbon dioxide from the atmosphere in an attempt to combat climate change and global warming. 

It is important to keep paying attention to climate change and global warming, consumption of natural resources, and the method of energy generation and consumption all of these issues are directly connected with the future environment. As polymer scientists, we are very much required to conduct green polymer chemistry to preserve the environment as well as we can. 

The major debate on environmental threats provides an excellent illustration of this new shift. The exhaustion of oil reserves, the change in biological and climatic factors and global warming are all themes associated with huge risks (since they entail the end of our societies) but in which the scientific knowledge that does exist is dominated by contradictory theories and uncertainties. 

In addition, global warming is characterized by other important features that imply some difficulties in the implementation of the instruments provided by the standard economic theory of policy choice. First, we cannot determine with certainty both the dimension and the timing of climate change and the costs of the abatement of emissions. Second, the effects of GHG concentration in the atmosphere on climate are intergenerational and persistent across...
