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.
The energy that then radiates out from the surface, longwave radiation, is trapped by the same greenhouse gases, warming the air, oceans, and land. This process, appropriately dubbed âthe greenhouse effect,â is how global warming occurs. Black carbon, a particle rather than a gas, also has a very large warming impact. The greenhouse effect itself isnât a bad thing. In fact, Earth could never have become warm enough to sustain life without it.
