05 April 2022 - IPCC Sixth Assessment Report on Climate Change
Climate Change 2022: Mitigation of Climate Change
(IPCC, April 2022)
The Working Group III report provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.
UN climate report: It’s ‘now or never’ to limit global warming to 1.5 degrees
(UN, 04/05/2022)
Reacting to the latest findings of the Intergovernmental Panel on Climate Change (IPCC), the UN Secretary-General insisted that unless governments everywhere reassess their energy policies, the world will be uninhabitable.
His comments reflected the IPCC’s insistence that all countries must reduce their fossil fuel use substantially, extend access to electricity, improve energy efficiency and increase the use of alternative fuels, such as hydrogen.
Revolutionary changes in transportation, from electric vehicles to ride sharing, could slow global warming – if they’re done right, IPCC says
Alan Jen (The Conversation, 04/05/2022)
Around the world, revolutionary changes are under way in transportation. More electric vehicles are on the road, people are taking advantage of sharing mobility services such as Uber and Lyft, and the rise in telework during the COVID-19 pandemic has shifted the way people think about commuting.
Transportation is a growing source of the global greenhouse gas emissions that are driving climate change, accounting for 23% of energy-related carbon dioxide emissions worldwide in 2019 and 29% of all greenhouse gas emissions in the U.S.
The systemic changes under way in the transportation sector could begin lowering that emissions footprint. But will they reduce emissions enough?
We urgently need to cut emissions – the good news is we can do it quickly and relatively cheaply
Frank Jotzo (The Guardian, 04/05/2022)
Enormous opportunities to cut emissions deeply are there, the time to act is now, and it can be done at affordable cost.
That would be the shortest possible summary of the thousands of pages of careful assessment in the world’s definitive stocktake of how to limit future climate change.
The assessment report released by the Intergovernmental Panel on Climate Change implies that while limiting global warming to 1.5C is practically out of reach, staying below 2C is possible in practice. And it is no longer just a theoretical possibility as it used to be not too long ago.
We are not on track to limit warming to 1.5 degrees
Peter Thorne (The Irish Times, 05/05/2022)
Monday marked the publication of the third and final working group report from the current report cycle of the Intergovernmental Panel on Climate Change (IPCC). These happen every seven to eight years and have huge importance in guiding international policy decisions.
They represent a comprehensive assessment of the underlying scientific literature by hundreds of international experts in the field. Their summaries are approved line-by-line by all governments. They therefore represent the most comprehensive and rigorous snapshots of the scientific knowledge base arguably in any branch of science.
