A better tomorrow?
Brexit may be an unexpected boon for the UK's climate leadership. Here's how the UK can seize the initiative.

Replanting the world's great forests should be a central demand at COP24.
The Giant Sea Bass at the California Academy of Sciences. Fishes'sense of smell is highly affected by high level of carbon dioxide in the ocean.
Increase of carbon dioxide in the ocean affects the way fish detect predators, mates or food and could threaten not only individual fish but entire populations.
Over 99 percent of today’s plastics come from oil, but new bio-based options are becoming available.

One big problem with plastics is that they're largely made of petroleum. Sourcing bio-polymers from plants and bacteria has some big benefits – and the technology is starting to take off.
The renewable energy industry can also create jobs.

The idea of a renewable energy transition is exciting. It opens up space to think about enhancing democracy and decolonization.

Urban trees are literally made with the help of human breath – they turn the carbon dioxide we breathe out into the building blocks of plant growth. So your local trees have a piece of you inside them.
Technology exists to capture carbon dioxide from the atmosphere but it has a big cost.
Livestock is a significant source of methane, a potent but short-lived greenhouse gas.
New research has suggested a fresh way to account for greenhouse gases with different lifetimes in the atmosphere.
For a megacity, Tokyo is rich in trees.
In an increasingly urban world, trees can make a major difference. One study found that, for every dollar invested in planting, megacities saw a $2.50 return on their investment.
New research finds more CO₂ can actually make most plants smaller in the long-term - but the story for crops isn't so simple.
Australia will have to regulate its considerable shipping industry.
Until now, the international shipping industry has been excluded from the Paris Agreement and the Kyoto Protocol, despite its major contribution to global emissions.
The Loy Yang station will be the site of a new hydrogen fuel project.

AGL has announced plans to use coal to make hydrogen fuel at its Loy Yang A station in Victoria's Latrobe Valley. Wait, isn't coal made of carbon, not hydrogen? Yes, but here's how the process works.
In the future, traps for mosquito that spread the dengue and chikungunya virus could be made from the carbon dioxide in human breathe as well as body odour.
Researchers studied reef sands at Heron Island, Hawaii, Bermuda and Tetiaroa. In this photo, white areas show the predominance of sand on reefs.

Ocean acidification poses an increasing threat to the sediments that form the framework of coral reefs - within around 30 years, these carbonate sands may no longer be able to form.

It may be just as well the UK government scrapped its previous carbon capture competition.

It's not all bad news at Bonn – with low carbon precincts, living infrastructure and urban networks, cities are leading the charge against climate change.
Children march at the welcoming ceremony of the Conference of the Parties (COP23) in Bonn, Germany.
As delegates meet in Bonn for the latest rounds of climate talks, civil society, NGOs, cities, regional governments and businesses, are stepping up to work together toward climate goals.
The CO2 we produce when we put up buildings is large and virtually unregulated.
