- What is Climate change for you?
Climate change is any significant long-term change in the expected patterns of average weather of a region or the whole Earth over a significant period of time. Climate change is about abnormal variations to the climate, and the effects of these variations on other parts of the Earth. Many people do not know what it really amounts to, either due to unreliable sources or deliberate misinformation, which has led to a series of myths about climate change. In these pages, we tackle the subject from an objective, scientific viewpoint, discussing the causes and consequences of climate change and how it should be tackled. First, we need to clarify two concepts often mistaken for synonyms: climate change and global warming. There is an important difference between them, however, given that it is global warming that causes climate change. As the planet’s temperature rises more than it would naturally, the climate varies.Although it is certain that Earth has naturally warmed up and got colder during other eras, such cycles have always been much slower, taking millions of years, whereas now, within a period of just 200 years, we are reaching levels that in the past brought about extinctions.Before going over the causes and effects of climate change, let’s explain why you don’t care about climate change:
2.How do we know the Climate is changing?
Climate change refers to significant, long-term changes in the global climate.The global climate is the connected system of sun, earth and oceans, wind, rain and snow, forests, deserts and savannas, and everything people do, too. The climate of a place, say New York, can be described as its rainfall, changing temperatures during the year and so on.But the global climate is more than the “average” of the climates of specific places. A description of the global climate includes how, for example, the rising temperature of the Pacific feeds typhoons which blow harder, drop more rain and cause more damage, but also shifts global ocean currents that melt Antarctica ice which slowly makes sea level rise until New York will be under water.It is this systemic connectedness that makes global climate change so important and so complicated.
