Lämpötilanousu

Lämpötilanousu refers to the general increase in the average temperature of the Earth's climate system. This phenomenon is primarily driven by human activities, most notably the emission of greenhouse gases into the atmosphere. These gases, such as carbon dioxide and methane, trap heat, leading to a warming effect.

Scientific consensus indicates that the Earth's climate has been warming at an unprecedented rate over the past century. Evidence for this includes rising global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level. The Intergovernmental Panel on Climate Change (IPCC) regularly assesses the scientific, technical, and socio-economic information relevant to understanding climate change.

The consequences of lämpötilanousu are far-reaching and include more frequent and intense heatwaves, changes in precipitation patterns, sea-level rise, and impacts on ecosystems and biodiversity. These changes pose significant challenges to societies worldwide, affecting agriculture, water resources, human health, and infrastructure. Addressing lämpötilanousu involves reducing greenhouse gas emissions and adapting to the changes that are already occurring.
