#IPCC SYR Figure SPM.3 shows how projected impacts indicate rising pressures on ecosystems, human health, crops and fisheries with higher global warming. These projections are without additional adaptation, but underscore the urgency of prevention and preparation. @IPCC_CH 1/5 These examples are some of the multiple lines of evidence used in more comprehensive underlying assessments within WGII chapters on land and ocean ecosystems, health and food. Those chapters also provide info on adaptation options. 2/5

#IPCC SYR Figure SPM.6 visualizes how climate actions (or inaction) can help shift development pathways towards sustainability. 🧵1/5 Climate Resilient Development (CRD) means integrating measures to adapt to climate change with actions to reduce or avoid greenhouse gas emissions to advance sustainable development. Coordinated approaches allow us to build synergies and co-benefits. 2/5

Very proud to have led team developing #IPCC SYR Figure SPM.1, released today, which shows how current and future generations have different experiences with climate change. 1/4 I was born in 1980 and have already experienced more warming than my parents had by this time in their life. My kids’ future could have even steeper warming, and the extent of this change depends largely on climate action (or inaction) now and in next decade. 2/4
