Szélsőségek és klímaváltozás

The document explains how 'attribution' studies determine if global warming increased the likelihood or intensity of a specific extreme weather event. It warns journalists against three common errors: ignoring climate change, claiming it caused an event without evidence, or treating it as the sole cause. The guide provides specific findings for heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires, noting that while heatwaves are globally linked to warming, other phenomena like droughts and floods vary significantly by region.

• Attribution studies use climate models to compare the current warmed climate with a simulated world without human-induced greenhouse gas emissions and aerosols to determine how much climate change increased the probability or intensity of an event.
• Heatwaves globally have become more frequent and intense due to human-induced climate change; for example, heatwaves that occurred once every ten years before the industrial era now occur 2.8 times in ten years and are 1.2°C warmer.
• Extreme rainfall has become more frequent and intense globally, particularly in Europe, much of Asia, central and eastern North America, parts of South America, Africa, and Australia, partly because warmer air holds more moisture (approximately 7% more per 1°C increase).
• While the overall annual number of tropical cyclones has not changed, climate change has increased the frequency of the strongest and most destructive storms, as well as the amount of extreme precipitation they produce.
• Extreme cold events are becoming rarer and milder globally, although heavy snowfall may have increased in intensity in specific regions such as North America, East and North Asia, and parts of Greenland.
• Droughts have become more frequent and severe in specific regions, including the Mediterranean, South Africa, Central and East Asia, Southern Australia, and the Western US, driven by increased evaporation and uneven precipitation.
• Fire-prone weather conditions have increased in frequency and duration on every continent in certain regions, most clearly in Southern Europe, North Eurasia, the United States, and Australia.
