Klimaskift, or climate change, refers to long-term alterations in statistical distribution of weather patterns over multiple decades or longer. It encompasses both global warming, the long-term rise in global temperatures, and the impacts of this warming on weather patterns worldwide. The primary cause of current climate change is human activity, specifically the emission of greenhouse gases such as carbon dioxide and methane, which trap heat in the Earth's atmosphere.

The scientific consensus is that climate change is primarily driven by human activities, particularly the burning of fossil fuels, deforestation, and industrial processes. These activities increase the concentration of greenhouse gases in the atmosphere, leading to a greenhouse effect that warms the planet. The Intergovernmental Panel on Climate Change (IPCC) has documented that the global average temperature has increased by about 1 degree Celsius since the pre-industrial era, with most of the warming occurring in the past few decades.

The impacts of climate change are widespread and include rising sea levels, more frequent and severe heatwaves, changes in precipitation patterns, and increased frequency of extreme weather events such as hurricanes and droughts. These changes pose significant risks to ecosystems, human health, and economies. For instance, rising sea levels threaten coastal communities and low-lying island nations, while heatwaves can lead to heat-related illnesses and deaths.

Mitigating climate change requires reducing greenhouse gas emissions and transitioning to renewable energy sources. Adaptation measures, such as improving infrastructure to withstand extreme weather events and developing early warning systems, are also crucial. International cooperation is essential for addressing climate change, as it is a global issue that requires collective action and shared responsibility.
