"Climate change has already altered the extreme weather we experience in Australia and will continue to do so over the coming years."

"We have already committed the planet to a certain amount of warming due to past carbon emissions. But efforts to reduce emissions now and over the next few decades will critically affect the degree of future warming."

"A carbon budget is like a household budget. You only have so much money to spend. How you choose to spend and invest your money will determine the available budget for your retirement and the legacy you provide for future generations."

"If we want a greater chance than 66% of limiting warming to two degrees, we would need to emit even less carbon dioxide. Conversely, if we accepted a lower probability of limiting the warming to two degrees, the budget would be higher."
