Описание слайда:

Introduction Climate change is the change in our weather patterns that are occurring because of an increase in the earth's average temperature. It is also known as global warming. Climate change may result from both natural and human causes though the human causes appear to be increasingly responsible for climate change over the past few decades

Conclusions Based on the results we got about our carbon footprints, we discussed different ways to reduce it without losing quality of life. We found out it’s quite hard, as new technologies aren’t always available in the market and are usually really expensive. In our country we can see many direct consequences of climate change: we’ve recently suffered from floods, droughts, we have hotter summers and colder winters (others even had snowfall in their cities, which is really unusual!).
