Common Questions

What is climate change?

The climate is changing because increased radiative forcing has disrupted the energy balance of our planet. This has large impacts on all our ecosystems. During the last decades the global temperature has increased, oceans have become warmer, snow and ice have melted and the sea level has risen. These observed changes have not occurred in earlier decades or millennia.

What causes climate change?

Electromagnetic radiation from the sun passes through the atmosphere to the Earth’s surface, where it is absorbed and  reflected back in the form of infrared heat waves. The incoming radiation and the outgoing energy should be in balance. This energy balance is what is called radiative forcing.

If the composition of the atmosphere is changed by increased greenhouse gases (GHGs), like carbon dioxide (CO2), methane (CH4) or nitrous oxide (N2O), this energy balance is disrupted. GHGs in the atmosphere are then blocking the outgoing heat from escaping the Earth, and therefore causing  global warming and the different consequences of climate change. 

Over millions of years energy from the sun has been stored in geological reserves as oil, gas and coal. Since the industrial era, people have found means to use this energy, but during the combustion process large amounts of carbon dioxide is released to the atmosphere. 

GHGs can be measured from ice cores and directly from the atmosphere. These measurements indicate that historical anthropogenic GHG emissions have been rapidly increasing since the prehistoric era. Due to economic and population growth atmospheric concentrations of GHGs have increased to levels that are unprecedented in the last 800,000 years (IPCC Climate Change 2014 Synthesis Report).
