"This study demonstrates that climate has undergone large changes long before humans started releasing large amounts of greenhouse gases into the atmosphere, indicating that natural forcings should be taken into account when trying to understand the climate of the future."

tuohon juttuun nuo käppyrät, jotka kertovat mitä ovat esim ns. "expected natural drivers" tai "forcings per square meter"?
Ovatko ne mitattuja arvoja?
tuhatta vuotta siitä keskiajan lämpimästä kaudesta on? Montakos tuhatta vuotta siitä oli ns. pikku jääkauteen.
