The United Nations Intergovernmental Panel on Climate Change We released the third and final article of the latest Climate Assessment Report on Monday. It provided a faint light of hope, but the big picture was dark.
Report, “Climate change 2022: Climate change mitigationIs the global greenhouse effect by 2025 at the latest, as it limits warming to about 1.5 degrees Celsius (2.7 degrees Fahrenheit), which is a threshold at which significant ecological collapse is likely to occur. We conclude that gas emissions have peaked and need to be reduced by 43%. By 2030. Methane also needs to be reduced by about one-third.
Still, world emissions are still rising, though not as much as in the first half of this century.
“This report shows that we haven’t done enough to reduce greenhouse gases,” said Inger Andersen, Under-Secretary-General of the United Nations and Managing Director of the United Nations Environment Program. “Half measures can’t halve greenhouse gas emissions by 2030. To increase action, we must start this year, not next year. This month, not next month. Tomorrow Not today. ”
In short, “it’s now or never,” said Jim Skier, co-chair of the working group that produced the report. (The report was edited by 278 authors from 65 countries who analyzed 18,000 scientific papers.)
As the title of the report suggests, the working group focused on the mitigations needed to achieve emission reduction targets. Recommendations have been made across sectors such as energy, transportation, agriculture, industry, buildings, finance and investment.
“What we did is very clear about what needs to happen,” Skea said.
The energy sector needs a major transition in the first stage, which accounts for one-third of all greenhouse gas emissions. The transition from fossil fuels to renewable energy sources will be important not only from an energy perspective, but also for transportation where the transition to electric vehicles will only win if the power sector is decarbonized, the report said. Lead author.
Urban areas need to invest in green and blue infrastructure. The industry needs to minimize waste. She said the building needs to be remodeled for sustainability and reduced energy consumption. Land use should emphasize the protection and restoration of natural ecosystems (forests, peatlands, grasslands, wetlands, savanna) that remove and store carbon.
According to the panel, governments will invest resources in the economy to initiate post-COVID activities, so these mitigations need to be kept in mind.
For the first time in its history, the evaluation of the panel Chapter on consumer demand and behaviorAccompanied by lifestyle changes among undeveloped mitigations.
These include abandoning cars with priority on walking, cycling and transit. Reduce air travel or choose high-speed rail. I live in a small house or a multi-generational household. Reduction of food waste; migration from meat and dairy products to other protein sources. Regarding the purchase of clothing and electrical appliances, purchase products that last longer. Relax the air conditioning of the house. All of this needs to be supported by broader systematic changes, Urge-Vorsatz added.
Lifestyle changes should not be equated with the recent austerity of COVID-19 restrictions. 2020 is an outlier in terms of witnessing global emission reductions.
The pandemic has shown the usefulness of digital technology, but when it comes to enabling video conferencing between participants around the world and everyone traveling to distant sites, “confining yourself is the net. It’s not a way to reach zero, “Skea said. ..
He said commitments from all sectors of society would be needed to enact the mitigations presented by the working group.
“We know what to do. We know how to do it,” Skea said. “We need to take action now … otherwise 1.5 degrees will slip out of reach.”
The Intergovernmental Panel on Climate Change has three working groups. The basics of the physical sciences of climate changeWorking Group II dealt with impacts, adaptations and vulnerabilities. Working Group III was responsible for mitigating climate change.
