Global Warming
Global Warming Impacts: Deadly Weather



The IPCC projects that more frequent and more severe heat waves will be one lethal effect of global warming. Deadly stretches of hot days, where nighttime temperatures remain high, will become more common. One such event killed over Chicago during the summer of 700 people in 1995. Based indicates on past heat wave events, research that by the year 2020, global warming could cause up to a 145% rise in mortality in New York City. Other major cities could suffer similar problems.

Regional climate stress on agriculture may mean up to 300 million additional victims of malnutrition world-wide each year. Extreme floods and droughts are projected to become more severe as global warming worsens. These extremes may threaten the availability and supply of safe drinking water. Diseases associated with flooding, such as cryptosporidiosis, could affect millions more people every year.

Extreme weather events, like the abnormal storms and flooding that have devastated many communities across America in recent years, may also become more common. As the number and severity of these events increase they will pose not only an immediate threat to human health and well being, but also bring dangerous long-term consequences.
