The causes of climate warming and human responsibility

Abstract

It is a fact that our planet’s surface is warming, but why? Many factors influence the Earth’s climate. Firstly, the Sun – the driving force behind the climate system – but also volcanic activity and the greenhouse effect. Certain greenhouse gases are naturally present in the atmosphere and trap heat on the Earth’s surface, keeping the average temperature at +15°C when it would be -18°C without them. Since the Industrial Revolution, human activity (industry, energy, construction, transport, agriculture, deforestation, etc.) linked to very high population growth has also produced greenhouse gases which have joined those already present in the atmosphere. Despite the arguments of those who call themselves ‘climate sceptics’, climatologists are virtually 100% certain that human contribution to the greenhouse effect is responsible for most of the global warming observed since 1950.
