The 1.5°C limit means we can avoid the worst of the climate crisis

The IPCC Special Reports SR1.5 and SR Land are clear: limiting warming to 1.5°C can avoid the worst impacts of climate change. Compared to 2°C of warming, 1.5°C would see much less severe extreme events, for example mid-latitude heat waves would be 1°C colder on average. There would also be fewer disruptions to human and ecological systems – crop yield change would affect 158 million fewer people. Limiting warming to 1.5°C means substantially fewer people would be impacted by water scarcity, lack of food security and extreme poverty. The 1.5°C warming limit is still within reach limiting warming to below 1.5°C is still possible but requires very urgent and rapid action now. Stringent emission reductions need to take place in the very near-term to halve current projects for 2030 CO2 emissions. 1.5C pathways require CO2 emissions to peak now and reach net zero by mid-century, with total greenhouse gases quickly following suit in the second half of this century.

No further discussion needed. The agreed global goal is to limit temperature rise to 1.5°C

The agreed global goal is to limit temperature rise to 1.5°C. Now countries must act to make this happen. This briefing explains the scientific and political process which led to countries committing explicitly to limit temperature rise to 1.5°C. Instrumental to these decisions was a process called: the Periodic Review of the long-term global goal under the Convention and of overall progress towards achieving it (PR2). The briefing also gives an overview how the Kyoto Protocol was implemented and which greenhouse gas reductions were achieved.
