US president-elect Donald Trump's expected climate rollbacks will likely have a "small" impact on global warming, as long as other countries resist the temptation to slacken their own carbon-cutting efforts, new research found Thursday.
Trump, who will return to the White House in January, has pledged to reverse the green policies of President Joe Biden and could pull the United States out of international efforts to limit global warming to 1.5 degrees Celsius above preindustrial times.
