The last chapter of Lakes and Ponds deals with how human activities affect the natural ecosystems and their function through eutrophication, contamination, acidification, brownification and increases in UV radiation, and how such anthropogenic disturbances may affect biodiversity and the ability of organisms to utilize a specific habitat. In addition, the chapter addresses novel environmental threats, such as global climate change and effects from our everyday chemicals, such as contraceptives, nanoparticles and antidepressant drugs. However, also possibilities and signs of improvement are discussed, providing hope for coming generations.

This review paper is based on the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change, in particular on the Working Group I (WG I) ‘The physical science basis’ and on the WG II ‘Impacts adaptation and vulnerability’ reports. The WG I report represents the state of the current scientific understanding of the observed and projected climate changes. The natural and anthropogenic drivers of climate change are addressed, focusing on the physical science understanding of observed records and on model-generated global climate change scenarios. The WG II report concerns the relationship between the observed changes of climate variables and the changes in the natural and human environment, addressing key policy-relevant scientific findings. Projected impacts and findings about vulnerability and adaptation on fresh water, natural ecosystems, food, fiber, coastal areas industry and health are also addressed for all continents. Scientific findings subsequent to the publication of the AR4 are not included in this review paper, whereas the recent decisions by the European Union (EU) and the agreements adopted within the United Nation Framework Convention on Climate Change based on the AR4 are reported.

Global climate change has far-reaching impact on natural ecosystems and the socio –economic system, which has called for attention of governments and scientific community and even the general public now. In the background of global climate change, the study of the effect of climate change on crop potential production has an important theoretical and practical significance. The relationship between wheat productivity and climate change and the response of the wheat productivity to the climate change were studied with Suzhou, China being a study area, aiming to provide a scientific basis for rational development and utilization of climate resources against the global climate change in Suzhou. The results showed that the annual average temperature of Suzhou tended to increase by 0.23°C per 10 years from 1977 to 2007. The annual precipitation has not been increased obviously over the recent 30 years. In the terms of annual change of climatic productivity of wheat, the average wheat productivity on the whole showed a increasing trend the last 50 years. However, the potential climatic productivity of wheat every decade first decrease and then increased. The correlation analysis indicated that there were assume the weak and assumes the strong correlations between the wheat climate productivity and the temperature and the precipitation with their relation coefficients (R) are R=0.04187 and R=0.70051, respectively. the influence of the precipitation to the Suzhou wheat climate productivity is higher than the temperature obviously . But there were the strong correlations between the wheat actual output and the temperature and the precipitation, therefore, the temperature and the precipitation are the important attributes that enhances wheat climate productivity realization rate.
