Climate impacts: why global warming is bad for your health. The costliest impact of climate change in Europe this century is likely to be on human health â and in particular heat-related deaths â according to a new economic assessment by the EU Joint Research Centre, the European Commissionâs in-house science service.
Global warming is caused by a phenomenon known as the greenhouse effect. A greenhouse (or glasshouse) is good for growing things because it traps heat inside and stays hotter than the atmosphere around it.t's not really warming up noticeablyâat least not in the short term. In fact, since 1900, the whole planet has warmed up only by around 0.8 degrees Celsius. By the end of the 21st century, however, global warming is likely to cause an increase in Earth's temperature of around 2â5 degrees Celsius.
