Monitoring Global Climate Change

Greenland Ice Sheet

Sateellite imageries can be useful for monitoring Global Warming. On the basis of satellite data Climate scientists  issued a warning on global warming, prompting a UN demand for politicians to tackle the global warming crisis. Global average surface temperatures could rise by between 1.1 °C (1.98 °F) and 6.4 °C (11.52 °F) compared to 1980-99 levels. Sea levels will rise by at least 18 centimeters (7.2 inches). Heat waves, rainstorms, tropical cyclones and surges in sea level are among the events expected to become more frequent, more widespread or more intense this century.

The extent of these changes has prompted concern about the possible effects on the global physical, chemical and biological systems. Large-scale changes in land use at rates unprecedented in human history are provoking considerable concern. Land use change is frequently accompanied by alterations or changes in land cover, which may possibly contribute to subsequent environmental change. Evaluation of static attributes (types, amount and arrangement) and the dynamic attributes (types and rates of change) on satellite images may allow the types of change to be regionalized and the proximate sources of change to be identified or inferred. This information, combined with results of case studies or surveys, can provide helpful input to informed evaluations of interactions among the various driving forces.

In these Imageries the shrinking of Greenland Ice Sheet is visible.

    The magic word here is “could”. Temperatures could also drop by this amount. After all, there’s been no increase in the past 10 years. Antarctic ice has increased. There’s a lot of reports coming out using “if” and “could”. These are not predictions – just “what if” situations that keep scientists busy. We need to keep them in perspective.
