Carbon Budget

• Carbon Budget till 2100 for >66% chance– ΔT= 2°C ~ 1,000 Gt of CO2 – ΔT= 1.5°C ~ 600 Gt of CO2

• Carbon content of reserves >> 1000 Gt CO2 • Current emissions ~ 36 Gt/y < 2 decades to use up carbon budget

Ice Mass Loss from the Two Polar Ice Sheets

How fast these two polar ice sheet melt determine how quickly sea level rises. Much uncertainty in timing of major melt such as WAIS

Recent results show fast retreat of the grounding line of important glaciers. There is no hill in the marine based topography left to anchor these glaciers. They have passed the point of no return.Adapted from Wouters et al., 2013

“The Worst Gas Leak in California’s History Isn’t Close to Being Fixed”“Infrared Camera Reveals Huge Cloud of Methane over California’s Aliso Canyon”“Gas Co. Vows to Shut Down Aliso Canyon Natural Gas Well After Leak Is Fixed”

Over 700 households have at least temporarily relocated.The site at Aliso Canyon has a capacity of 86 billion cubic feet.

Solutions:Leave Fossil Fuels in the ground

• Leave all unconventional oil and gas in the ground because existing reserves and resources are incompatible with 2ºC climate policies due:– Quantity available – High carbon content – Probability of methane leaks increases with
