The first Australian climate court case brought on behalf of First Nations people has heard climate \u201ctipping points\u201d could be reached that would rapidly lead to irreversible changes, such as sea level rise.<\/p>\n
Two Torres Strait community leaders, Uncle Paul Kabai and Uncle Pabai Pabai, have taken the Australian government to the Federal Court, alleging it failed to protect First Nations traditional owners living on the front line of catastrophic climate change.<\/p>\n

That reading is now over 500 parts per million.<\/p>\n Karoly said examples of tipping points include, for instance, the loss of sea ice around Antarctica or the Arctic, which open up additional ocean water: \u201cThe loss of sea ice is an accelerating process that can accelerate global warming.\u201d<\/p>\n Professor Karoly was questioned by the barrister representing the Australian government, Stephen Lloyd, SC, about whether he was a climate \u201cadvocate\u201d.<\/p>\n Karoly said he had been primarily advocating the science of climate change: \u201cIf that makes me a climate change advocate, then yes.\u201d<\/p>\n \u201cWould you accept it\u2019s not possible for Australia by itself to set any greenhouse gas emissions target or take any other action that would hold global temperatures to 1.5 degrees above the baseline?\u201d Lloyd asked.<\/p>\n (Left to right) Uncle Paul Kabai and Uncle Pabai Pabai.<\/span>Credit: <\/span>Joe Armao<\/cite><\/p>\n Karoly said that Australia was an important part of global action to reduce greenhouse gas emissions.<\/p>\n Lloyd asked if Karoly was an advocate of using litigation as a way to cause the government to take further action on climate change, noting he had attended a workshop in 2016 on climate litigation.<\/p>\n Karoly said he had attended a number of climate litigation workshops, including one run by the Australian Academy of Science and the Australian Academy of Law, in his role as an expert on the causal links between greenhouse gas emissions and temperature increases.<\/p>\n This landmark Torres Strait climate action is modelled on one of the most successful global climate cases in history, in which the Urgenda Foundation supported 886 people to bring a case in 2015 against the government of the Netherlands. A Dutch District Court ordered the government to cut its greenhouse gas emissions by at least 25 per cent by the end of 2020 (from 1990 levels).<\/p>\n Specialist law firm Phi Finney McDonald is conducting the litigation on behalf of the two Torres Strait men, with support from Urgenda and Grata Fund, a public-interest organisation that supports marginalised people to advocate for their legal rights.<\/p>\n<\/p>\n
