প্রতিকূল/বিরূপ আবহাওয়া এবং জলবায়ু পরিবর্তন সংক্রান্ত রিপোর্টিং সাংবাদিকদের জন্য নির্দেশিকা

The document serves as a manual for journalists to avoid common errors when linking specific weather events to climate change. It details the methodology of 'event attribution studies'—which use climate models to compare the current world with a pre-industrial one—and provides specific guidance on reporting heatwaves, floods, tropical cyclones, heavy snowfall, droughts, and wildfires. The guide emphasizes that while climate change increases the probability and intensity of many extremes, it is rarely the sole cause, and local factors like land use and water management often play critical roles in turning a weather event into a disaster.

• Journalists frequently make three specific errors when reporting on extreme weather: ignoring climate change as a cause, blaming climate change without evidence, or attributing a single extreme event solely to climate change.
• Event attribution studies use climate models to determine how much human-induced climate change altered the likelihood or intensity of a specific event; for example, research showed that human-induced climate change made the 2003 European summer heatwave at least twice as likely.
• Heatwaves have the strongest and most direct link to global warming; a 1°C increase in global temperature makes heatwaves more than 1°C hotter, and some extreme heatwaves in Canada and the US in 2021 would have been 'impossible' without human-induced climate change.
• Climate change increases rainfall intensity because a warmer atmosphere holds more moisture—approximately 7% more per 1°C of warming—though the link to specific floods is complex due to human factors like poor drainage and land use.
• While the total number of tropical cyclones globally may not be increasing, climate change is increasing the proportion of high-intensity storms (Category 3-5) and increasing the amount of rainfall they carry.
• The relationship between climate change and heavy snowfall is highly uncertain; while some high-latitude regions in Asia and North America may see increased intensity, many individual events are driven by natural variability.
• Drought risk is increasing significantly in specific regions including the Mediterranean, South Africa, Central and East Asia, South Australia, and Western North America due to increased evaporation and shifting rainfall patterns.
• Climate change is extending the duration of 'fire weather' seasons and increasing the probability of wildfires across all continents, with strong evidence in South Europe, North Eurasia, the US, Australia, and South China.
