Australia should accelerate its emissions cuts by bringing its target forward by five years, Marshall Islands foreign minister Tony de Brum says, while warning that his tiny Pacific nation was already feeling the effects of climate change. Mr de Brum's comments came during Opposition Leader Bill Shorten's visit to the Marshall Islands. Mr Shorten (pictured) said Labor would embrace more ambitious climate targets for Australia in line with keeping global warming below 2 degrees. The Marshall Islands government has been critical of Australia's climate goal to cut emissions by 26 to 28 per cent from 2005 levels by 2030, describing it as weak. Mr de Brum said he would be happy if Australia kept the same emissions cut but sought to achieve it five years earlier. "I think if they can move their date from 2030 to 2025 with the same figures, that is a very good beginning," he said. Mr Shorten said Labor was visiting the Marshall Islands to see firsthand the impact of climate change as it formulated its policies.
