WARSAW, Poland (AP) -- A spate of bad news hangs over U.N. climate talks as they head into a tense final week.
The two-decade-old negotiations have so far failed to achieve their goal of slashing emissions of CO2 and other greenhouse gases that scientists say are warming the planet.
Setbacks last week included Japan's decision to ditch its voluntary emissions target and legislation introduced by Australia's government to scrap its carbon tax on industry.
No major carbon polluters raised their pledges to cut emissions.
And Brazil reported that annual destruction of its Amazon rainforest jumped by 28 percent after four straight years of declines.
Though no major decisions are on the agenda in Warsaw, Poland, the talks are meant to pave the way for a bigger global climate treaty in 2015. Environmental groups watching the first week of talks are discouraged.
