The battle between weather skepticism and climate reality shapes global policy debates
7 days ago
0
Why does climate science focus on long-term averages rather than daily weather?
Because daily weather data is too difficult to collect accurately.
Because climate and weather are the same, so long-term averages are just a simplified approach.
Because climate reflects patterns over decades, revealing trends that daily weather cannot show.

Why are CISN ShakeMaps critical for emergency response after an earthquake?
Because they provide rapid, detailed maps of shaking intensity to prioritize aid and resources.
Because they predict earthquakes days before they happen.
Because they only record the earthquake magnitude without location details.

What distinguishes climate research from weather studies in terms of the time period analyzed?
Climate research focuses only on ocean temperatures, whereas weather studies focus on atmospheric conditions.
Climate research studies atmospheric conditions averaged over at least 30 years, while weather studies focus on short-term atmospheric conditions.
Climate research studies daily weather patterns, while weather studies analyze yearly averages.
