President Trump gave Obama all the incentive he may have needed when Bloomberg reported Monday that the Trump administration is disbanding an interagency panel created by Obama to help cities deal with the effects of climate change.
"We sought to set ambitious climate targets globally", the former president told the summit.
The news release that announced the meeting was issued by Chicago Mayor Rahm Emanuel in September and specifically cited the Trump administration's announcement to pull out of the Paris Agreement on climate change. Or, in other words, much like with Sanctuary Cities, an effort to circumvent the US government under Trump to advance the liberal agenda.
Former President Obama is in Chicago addressing mayors on climate change, after President Trump chose to withdraw the USA from the agreement.
Other mayors attending include Valerie Plante of Montreal and Miguel Angel Mancera of Mexico City. "We lead respectively where there is no consensus or directive out of our national governments".
Trump further argued if the Paris agreement were completely implemented by all countries, "14 days of carbon emissions from China alone would wipe out the gains from America".
Earlier, Obama also discussed climate issues with Paris Mayor Anne Hidalgo. He says mayors will sign a charter and discuss solutions including expanding access to public transportation.
Chicago officials said the idea is to fill the void left by the actions of Trump, who has worked to reverse much of Obama's approach to foreign policy.
