Climate change and terrorism are expected to dominate talks as the second day of the G7 summit of economic powers gets under way in Germany. Chancellor Angela Merkel wants the group to reach an agreement on limiting global temperature rises. She also wants G7 members to contribute to a fund for poor countries suffering the worst effects of climate change. There will also be talks on the threat from radical extremism with the leaders of Nigeria, Tunisia and Iraq. The summit is being held at the picturesque Schloss Elmau hotel in Kruen in the Bavarian Alps. It is being attended by US President Barack Obama, UK Prime Minister David Cameron, Japanese Prime Minister Shinzo Abe, French President Francois Hollande, Canadanian PM Stephen Harper and Italian PM Matteo Renzi. The first working session on Monday will focus on climate and energy, with Chancellor Merkel trying to get leaders to agree to keeping temperature rises within 2C of pre-industrial levels. She is hoping to secure commitments from her G7 guests on tackling global warming to build momentum before a major United Nations climate summit in Paris in December. 'Biggest threat' Later, G7 leaders will be joined by Iraqi PM Haider al-Abadi, Nigerian President Muhammadu Buhari and Tunisian President Beji Caid Essebsi to discuss the threat posed by groups like Islamic State (IS) and Boko Haram. On Sunday, Mr Cameron said the UK was sending an extra 125 military trainers to Iraq to help in the battle against IS, describing the militants as "the biggest threat" G7 leaders had to address. IS continues to control large swathes of Iraq and Syria despite being the target of a US-led air campaign against them. In Nigeria, a similar regional battle is being fought against Boko Haram militants who have carried out attacks since 2009 to try to create an Islamic state.
