This document discusses the impacts of climate change and actions that can be taken to address it. It provides graphs showing rising global temperatures and impacts like coral bleaching. It emphasizes the need to urgently reduce emissions through solutions like renewable energy and energy efficiency. Individual actions are suggested like reducing flights and increasing tree planting, but it also stresses the importance of collective action through institutions and elected leaders enacting climate policy.

18. GLOBAL WARMING OF 1.5 °C
an IPCC special report on the impacts of global
warming of 1.5 °C above pre-industrial levels and
related global greenhouse gas emission pathways,
in the context of strengthening the global response
to the threat of climate change, sustainable
development, and efforts to eradicate poverty
We must urgently and aggressively reduce emissions,
while preparing for our climate of now.
low-carbon energy & energy efficiency
increase natural uptake of CO2
social & cultural change
new partnerships & planning for resilience

19. If we want to hold warming to less
than 2°C (4F), then we need to get
to NET zero emissions by 2040.

20. The good news: we only have to reduce our
emissions by 50%

21. And halting tropical deforestation would save
10% of our annual emissions

if we start now, and work together, we
