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.
Who will emerge as the leader on climate change following the U.S. withdrawal from the Paris agreement?

Canada ratified the Paris agreement on climate change, but it hasn't yet filled the leadership void left by the United States. Time is running out.
Human activity, along with a strong El Nino, drove 2016 greenhouse gas levels to new heights.

Global greenhouse gas levels have hit their highest point in at least 3 million years, according to new figures from the World Meteorological Organisation.
Carbon dioxide flux over China, measured by NASA’s Orbiting Carbon Observatory-2 satellite.
New data from a NASA satellite show in unprecedented detail the flow of carbon dioxide into the atmosphere. Future satellites should even be able to detect the signatures of individual power stations.
The window for staving off the worst of climate change is wider than we thought, but still pretty narrow.
It's still possible to hit the more ambitious of the two Paris global warming goals, according to a new estimate of the global carbon budget. But it sure won't be easy, and we need to start now.
Sea ice trapped atmospheric carbon dioxide in the last ice age.
The last ice age locked atmospheric carbon dioxide into oceans, which has major implications for how the oceans and carbon dioxide may be linked in the future.
