Collective action in response to climate change does depend on changes in individual choices and actions, then, but not those we tend to find on "how to make a difference" checklists.
It will be one of the main items discussed at a global conference in Poland in December, when governments will review the Paris Agreement (which the USA withdrew from in June 2017).
"One of the key messages that comes out very strongly from this report is that we are already seeing the consequences of 1°C of global warming through more extreme weather, rising sea levels, and diminishing Arctic sea ice, among other changes", said Panmao Zhai, Co-Chair of IPCC Working Group I. The report highlights how minimizing global temperature rise is critical. And carbon dioxide emissions must reach net zero around 2075 - meaning the amount of carbon dioxide entering the atmosphere equals the amount being removed.
More than ninety-one authors and review editors from 40 countries contributed to the findings which were launched in Incheon in South Korea on October 8 in front of all 195 signed on parties of the Paris Agreement.
Society would have to enact "unprecedented" changes to how it consumes energy, travels and builds to meet a lower global warming target or it risks increases in heat waves, flood-causing storms and the chances of drought in some regions, as well as the loss of species, a United Nations report said yesterday.
"It is pretty much impossible to reconcile Canada's commitment - which we agreed to in the Paris climate agreement - to avoiding 2 degrees and hopefully 1.5 degrees of warming, with decisions to expand the LNG industry", said Simon Donner, a climate scientist at the University of British Columbia. But even a 1.5°C rise in temperature will be threatening to India.
The coalition of scientists and policy experts predict the average global temperature will hit the crucial threshold of 1.5C above pre-industrial levels by 2030.
Scientists with the Nobel Prize-winning IPCC said in order to have even a 50-50 chance of staying under the 1.5 degree cap, the world must become "carbon neutral" by 2050. Coral reefs, which risk decline by more than 99% at 2C, would reduce by 70 to 90%.
The report says the world will need an annual average investment of 2.4 trillion dollars between 2016 and 2035 (which is 2.5% of present world GDP) in energy system alone to limit the global warming to 1.5 degree celsius. It would also cut down on species loss and extinction and reduce the impact on various ecosystems. Climate change is moving faster than we are....
What Will We See Once Global Warming Is Limited To 1.5C?
"Such large transitions pose profound challenges for sustainable management of the various demands on land for human settlements, food, livestock feed, fibre, bioenergy, carbon storage, biodiversity and other ecosystem services", the report stated. President Macron's One Planet Summit followed in NY during Climate Week, bringing together leaders of finance who were optimistic that managing climate risk is not only possible, but an exciting challenge that would also be profitable as new industries arise to do the most important work the world has ever demanded.
Hong Kong's climate action plan, published past year, only pledges a 26 to 36 per cent cut by 2030 from 2005 levels.
