A few amazing FACTS:● The Earth was never so cold● Temperature does not follow CO2● CO2 not the strongest greenhouse gas
A few amazing FACTS:● The Earth was never so cold● Temperature does not follow CO2● CO2 not the strongest greenhouse gas ● From ‘40-’75 and since 2000 no rise
Climate HISTORY = FACT = “EASY” Climate FUTURE = ”FICTION” = COMPLEX
Alpine glaciers Sea ice Continental ice sheet
Glaciers are not simply melting, but disintegrating
Arctic albedo “Arctic death cycle”
The Great Ocean Conveyor Permafrost methane
“Big Five” ExtinctionsEnd-OrdovicianLate DevonianEnd-PermianEnd-TriassicEnd-Cretaceous (“K/T”) Suggesed main causesSea-level falls Flood basalts Impact event Other causes (also of smaller extinctions):Global cooling / warming, “Clathrate Gun”, Anoxic events in oceans,Hydrogen sulphide emissions from oceans, Oceanic overturn, Nearby nova, super-nova or gamma-ray bursts..(Near) future causes: HUMAN ACTIVITY..?

Conclusions:● The climate system is vast, complex and unpredictable
Conclusions:● The climate system is vast, complex and unpredictable ● We’re currently living in a near infinitesimal bandwidth of the ecological spectrum
Conclusions:● The climate system is vast, complex and unpredictable ● We’re currently living in a near infinitesimal bandwidth of the ecological spectrum● Human caused impact is real but should not be the main motivation for (technological) progress
Why care: 3. Global ecosystem
Why care: 2. Current species and civilisation – scarcity, famine, war, mass migrations 3. Global ecosystem
Why care:1. Mentality shift – tackle inequality, poverty, big oil monopoly, etc..2. Current species and civilisation – scarcity, famine, war, mass migrations 3. Global ecosystem
