Piers Forster, director of the Priestley International Centre for Climate at the University of Leeds, called the decision to withdraw « a sad day for evidence-based policy » and expressed hope that some Americans, businesses and states would choose to decarbonize. Climate scientist Dave Reay, from the University of Edinburgh, said, « The United States is coming to the streets today. » The University Corporation for Atmospheric Research (UCAR) said in a statement by its president Antonio Busalacchi Jr. that the decision to withdraw « does not mean that climate change will disappear » and warned that « the increased potential for greenhouse gas emissions poses a significant threat to our communities, our businesses and the military. » The Foundation for Information Technology and Innovation called the decision to withdraw « very disheartening » and said it would reduce confidence in international efforts to combat climate change; The technology think tank called for federal efforts on « smart grid, energy storage, carbon capture and sequestration, as well as advanced nuclear and solar energy, » and warned, « Without a smart and aggressive clean energy innovation strategy, the world will not avoid the worst consequences of climate change. »  Trump`s exit from the Paris agreement will affect other countries by cutting financial assistance to the Green Climate Fund.  The end of US funding of $3 billion will have a final impact on climate change research and will reduce society`s chances of meeting the Paris Agreement goals and omit U.S. contributions to future IPCC reports.   Trump`s decision will also affect CO2 emission space and carbon prices.  The withdrawal of the United States will also mean that the place where the global climate regime can be adopted will be accessible to China and the EU.  On August 4, 2017, in an official statement addressed to the United Nations as a custodian, the Trump administration officially announced its intention to revoke the withdrawal.  In a separate statement, the Ministry of Foreign Affairs said it would continue to participate in international climate change negotiations, including discussions on the implementation of the climate agreement.
  Several environmental groups such as the Sierra Club and the Natural Resources Defense Council have condemned Trump`s decision.   American environmentalist and writer Bill McKibben, founder of the 350.org Climate Change Action Group, called it « a stupid and ruthless decision – our nation`s stupidest act since the start of the Iraq war. » McKibben wrote that Trump`s decision to step down « is a complete rejection of two civilizing forces on our planet: diplomacy and science. » He asked the United States:
