Cloze.Climate change poses threats to resources both domestically and internationally. These threats could have significant, but uncertain, socioeconomic c______ . Changes in temperature, precipitation and sea level driven by climate change can a______ to existing stresses on resources caused by other f______ such as population growth, land-use changes and pollution. Developing countries are more v______ than developed countries to climate change because of their socio-economic conditions. Overall, variable strategies for coping with climate change can be i______ for "intensively managed" systems (such as agriculture, water resources and developed coastlines). For these systems, technological and management options exist to some extent today, a______ they may be costly to implement. With time, more e______ responses can be developed for these sectors. By comparison, fewer options can be identified for natural systems (such as wetlands and wilderness areas). Natural ecosystems will be degraded because the composition, geographic distribution and productivity of many ecosystems will change as individual species r______ to changed climate. This will likely l______ to reductions in biological diversity and in the goods and services ecosystems can p______ for society. Temperature changes expected from the enhanced g______ effect have occurred in the past, but the previous changes took place over centuries or millennia instead of d______ . Rates of natural migration and adaptation of species and communities appear to be much faster than the p______ rate of climate change. One of the consequences of global climate change may be increases in the frequency of some e______ weather events, particularly droughts and floods. Of course, we cannot absolutely r______ climate change to specific events. However, these events, when they do occur, can be costly.
