The world’s leading scientists have projected that in the coming decades climate changes will increase in all regions, and there would be increasing heat waves, longer warm seasons and shorter cold seasons.
“We now have a much clearer picture of the past, present and future climate, which is essential for understanding where we are headed, what can be done, and how we can prepare,” the scientist said
The report, titled “Climate Change 2021: the Physical Science Basis,” was drafted by IPCC Working Group I and got approved on Aug. 6 by 195 members of the IPCC through a virtual approval session that was held over two weeks starting on July 26.
The UK is calling for urgent global action in response to a UN report.
This latest report published is a stark warning from scientists around the world that human activity is damaging the planet at an alarming rate.
The report warns that climate change is already affecting every region across the globe and that without urgent action to limit warming, heatwaves, heavy precipitation, droughts, and loss of Arctic Sea ice, snow cover and permafrost, will all increase while carbon sinks will become less effective at slowing the growth of carbon dioxide in the atmosphere.
The report highlights that cutting global emissions, starting immediately, to net zero by mid-century would give a good chance of limiting global warming to 1.5C in the long-term and help to avoid the worst effects of climate change.
The Prime Minister Boris Johnson said: “Today’s report makes for sobering reading, and it is clear that the next decade is going to be pivotal to securing the future of our planet. We know what must be done to limit global warming – consign coal to history and shift to clean energy sources, protect nature and provide climate finance for countries on the frontline.
“The UK is leading the way, decarbonising our economy faster than any country in the G20 over the last two decades. I hope today’s IPCC report will be a wake-up call for the world to take action now, before we meet in Glasgow in November for the critical COP26 summit.”
As extreme events are felt across the globe, from wildfires in North America to floods in China, across Europe, India and parts of Africa, and heatwaves in Siberia, COP President Alok Sharma has been negotiating with governments and businesses to increase global climate ambition and take immediate action to help halve global emissions in the next decade and reach net zero emissions by mid-century in order to keep the 1.5C goal set out in the Paris Agreement within reach.
The UK is already showing leadership with clear plans to reduce its emissions by 68% by 2030 and 78% by 2035, leading to net zero by 2050. Today, more than 70% of the world’s economy is now covered by a net zero target – up from 30% when the UK took over as incoming COP Presidency. May saw the establishment of the first net zero G7, with all countries coming forward with 2030 emission reduction targets that put them on a pathway to reaching this goal by 2050. However, today’s report shows that more action is urgently needed.
In a meeting with scientists, Alok Sharma encouraged countries that have not already done so, to urgently submit new or updated NDCs with their plans for ambitious climate action ahead of the vital COP26 summit later this year in Glasgow, particularly all major economies of the G20 who are responsible for over 80% of global emissions.
In response to the report, Mr Sharma said: “The science is clear, the impacts of the climate crisis can be seen around the world and if we don’t act now, we will continue to see the worst effects impact lives, livelihoods and natural habitats.
“Our message to every country, government, business and part of society is simple. The next decade is decisive, follow the science and embrace your responsibility to keep the goal of 1.5C alive.
UK International Champion on Adaptation and Resilience for the COP26 Presidency Anne-Marie Trevelyan said: “The impacts of climate change are already affecting lives and livelihoods around the world, with increasing frequency and severity. Alongside the need to drive down emissions, this report rings the alarm to urgently help vulnerable communities adapt and build resilience – in developed and developing countries alike.
