Ilmastoarvioinnit, or climate assessments, are systematic evaluations of the current and projected impacts of climate change. These assessments aim to provide policymakers, researchers, and the public with comprehensive and up-to-date information about climate change. They typically synthesize vast amounts of scientific data from various sources, including observations, climate models, and impact studies.

The primary goal of climate assessments is to understand the current state of the climate, identify trends and changes, and project future scenarios. This involves analyzing historical climate data to understand past variability and long-term trends, such as changes in temperature, precipitation, sea level, and extreme weather events. Future projections are based on sophisticated climate models that simulate the Earth's climate system under different greenhouse gas emission pathways.

Ilmastoarvioinnit also assess the potential impacts of these projected changes on various sectors and systems. This can include impacts on natural ecosystems, biodiversity, agriculture, water resources, human health, infrastructure, and the economy. They often highlight vulnerabilities and risks associated with different regions and populations.

Key outputs of climate assessments include reports, data summaries, and policy-relevant information. These outputs are crucial for informing adaptation and mitigation strategies. Adaptation refers to adjusting to actual or expected future climate. Mitigation involves efforts to reduce or prevent the emission of greenhouse gases. By providing a clear picture of the challenges posed by climate change, ilmastoarvioinnit play a vital role in guiding informed decision-making and promoting climate action. International bodies like the Intergovernmental Panel on Climate Change (IPCC) are prominent producers of such assessments.
