Levels of Carbon Dioxide in Atmosphere Increase
tmospheric levels of carbon dioxide, the principal heat-trapping gas, are continuing to rise at an accelerating rate, the National Oceanic and Atmospheric Administration reported. And after a decade of stability, levels of an even more potent heat-trapper, methane, rose as well. The agency said atmospheric levels of carbon dioxide reached nearly 385 parts per million last year, up from 280 in 1850 and an increase of 2.6 parts per million from 2006, chiefly from the burning of fossil fuels. The methane situation is less clear. Methane is produced naturally by swamps but also by activities including burning fossil fuels. The issue is important because climate experts have long worried that if Arctic permafrost thaws, the process would release potentially catastrophic amounts of methane into the atmosphere. In a statement, the agency said the most likely causes of the methane increase were economic development in Asia and emissions from Arctic wetlands. It said it was "too soon to tell" if the increase signals an Arctic thaw

The Imapatct of Global Warming to Coastal and Marine Environments
- The sea has an enormous capacity to store heat. Warmer water, combined with anticipated changes in ocean currents, could have a devastating impact on marine ecosystems and biodiversity.
- One potential result could be a reduction in the upwelling of nutrients, which would in turn reduce productivity in key fishing areas.
- Decreased growth may also be seen in coral reefs, with high concentrations of CO2 in the water impairing the deposition of limestone required for coral skeletons (UNEP, 2002).
A significant sea level rise is one of the major anticipated consequences of climate change. This will cause some low-lying coastal areas to become completely submerged, while others will increasingly face short-lived high-water levels. These anticipated changes could have a major impact on the lives of coastal populations. The small island developing states (SIDS) will be especially vulnerable to the effects of sea level rise, and to changes in marine ecosystems, because of their major dependence on marine resources (UNEP, 2002).
The extent of future sea level rise will depend on a multitude of factors, and is therefore extremely difficult to predict. While rising sea levels will be exacerbated by thermal expansion of the warming oceans, and the melting of land ice, they will be partially offset by increased precipitation over Antarctica (Met Office UK, 2001).
