Walker Swamp: The mission to restore an Australian wetland

# data[].attributes.attachment_link.readable_text
In the shadow of Australia's Grampians National Park lies Walker Swamp, a once-thriving wetland that was artificially drained and farmed for over a century.

But it is now welcoming new life once more, after a huge restoration project.

Its revival is one "message of hope" amid so much grim environmental news, ecologists tell the BBC.

We ask experts to imagine a world where we have halved global emissions by 2030

# data[].attributes.attachment_link.readable_text
Ahead of the crucial COP26 climate conference in November, experts chart the route to halving global GHG emissions by 2030.

The COP26 conference in Glasgow in November is going to be a very important moment in tackling climate change. We are currently not on track to meet the goal of limiting global temperature rise to between 1.5 and 2 degrees above pre-industrial levels. According to the UN Intergovernmental Panel on Climate Change, we need to halve total emissions by the end of 2030 if we're to be on track to hit the 1.5 degree target and avoid the worst effects of a changing climate. To close the gap between pledges and action, countries need to sign up to policies and strategies that start to reduce emissions now. This is the challenge for the summit in Glasgow.

Tom Heap is joined in the studio by Nigel Topping, the High Level Climate Action Champion for COP26, to discuss the ambition of the summit and the momentum that is building not just among governments but cities, investors and businesses to deliver net zero by mid-century. They hear from three experts who will give us real world practical solutions to achieve far-reaching carbon cuts by 2030: Dr Rhian-Mari Thomas, Chief Exec of the Green Finance Institute; Dr Stephen Cornelius, Chief advisor on Climate Change at WWF UK; and Dr Angela Wilkinson, CEO of the World Energy Council. Can we really halve emissions by 2030?
