Several global leaders gathered for a couple of meetings in Germany pledged to act on climate change, and craft a new climate treaty.

World leaders at the G-7 summit in Bavaria urged that some urgent and concrete actions need to be taken on climate change.

US President Barack Obama said he has observed that there has been progress towards a global treaty to replace the Kyoto Protocol, the agreement that expired in 2012.

Obama said, “We continue to make steps towards strong global climate agreement this year in Paris. All G-7 countries have put forward our post 2020 targets for reducing carbon emissions and will continue to urge other significant emitters to do so as well”.

World leaders said that the goal is to keep global temperatures from rising more than 2 degrees Celsius from pre-industrial times.

Experts said that the goal would avoid the most catastrophic impacts of climate change, like sea-level rise and more severe droughts and storms.

German Chancellor Angela Merkel said in a statement that binding rules for emissions reductions must be at the heart of any new climate agreement.

She said that the world does not have any binding rules at the moment, therefore it must be made a major goal in Paris.

The G-7 leaders also renewed a commitment to provide $100 billion annually, beginning in 2020, to help poorer nations adapt to climate change.

Merkel said it is very important to set these goals before the December climate conference which is scheduled to be held in Paris.

Developing countries and small island nations would otherwise face difficultly in accepting the agreement, she added.
