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. In order to limit global warming to 1.5°C, “rapid and far-reaching” transitions in land, energy, industry, buildings, transport, and cities are deemed necessary. CO2 emissions would need to fall by about 45% from 2010 levels by 2030, reaching ‘net zero’ around 2050. The contribution of nuclear power increases significantly under all IPCC scenarios which aim to keep global warming under 1.5°C.
This report is beautifully presented with a Summary for Policymakers and then the following chapters:
Chapter 1: Understanding the impacts of 1.5°C global warming above pre-industrial levels and related global emission pathways in the context of strengthening the response to the threat of climate change, sustainable development and efforts to eradicate poverty.
Chapter 2: Showing how emissions can be brought to zero by mid-century stay within the small remaining carbon budget for limiting global warming to 1.5°C.
Chapter 3: Why is it necessary and even vital to maintain the global temperature increase below 1.5°C versus higher levels? Adaptation will be less difficult. Our world will suffer less negative impacts on intensity and frequency of extreme events, on resources, ecosystems, biodiversity, food security, cities, tourism, and carbon removal.
Chapter 4: The global response to warming of 1.5°C comprises transitions in land and ecosystem, energy, urban and infrastructure, and industrial systems. The feasibility of mitigation and adaptation options, and the enabling conditions for strengthening and implementing the systemic changes, are assessed in this chapter.
Chapter 5: The interactions of climate change and climate responses with sustainable development including sustainable development impacts at 1.5°C and 2°C, the synergies and tradeoffs of mitigation and adaptation with the Sustainable Development Goals/SDGs, and the possibilities for sustainable and equitable low carbon, climate-resilient development pathways.
In the report, the IPCC confirms need for low-carbon nuclear to tackle climate change. Nuclear power is essential if the world is to keep global warming to below 1.5 degrees, according to the latest report by the Intergovernmental Panel on Climate Change (IPPC). Indeed, for electricity generation, the share of nuclear will need to increase significantly in order to meet global targets.
