lisäälämpeneminen

Lisäälämpeneminen is a Finnish term that translates to "additional warming" or "further warming." It generally refers to the ongoing increase in Earth's average temperature beyond the baseline warming observed due to anthropogenic climate change. While the primary focus in climate discussions is often on the overall warming trend, lisäälämpeneminen can specifically address scenarios where warming continues or accelerates due to feedback loops or exceeding certain climate thresholds.

This concept is relevant in understanding potential future climate impacts. For instance, if certain feedback mechanisms, such as the melting of permafrost releasing greenhouse gases or reduced ice albedo, significantly amplify the initial warming caused by human emissions, this amplified effect would be considered lisäälämpeneminen. It highlights the non-linear nature of climate change and the possibility of self-reinforcing warming processes.

Scientists use climate models to project different future warming scenarios, some of which incorporate these additional warming potentials. Understanding lisäälämpeneminen is crucial for setting ambitious climate mitigation targets and preparing for the most severe potential consequences of climate change. It emphasizes the urgency of reducing greenhouse gas emissions to prevent crossing tipping points that could lead to irreversible and accelerated warming.
