Many researchers have studied the impact of carbon dioxide and heat on crop growth inside greenhouses. But what happens in the real world? One team has just done this and the results are surprising.

For the second year in a row global greenhouse emissions from fossil fuels have risen, putting 2018 on course to set a new record, according to an annual audit from the Global Carbon Project.
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.
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.
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.

New research has suggested a fresh way to account for greenhouse gases with different lifetimes in the atmosphere.

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.
Until now, the international shipping industry has been excluded from the Paris Agreement and the Kyoto Protocol, despite its major contribution to global emissions.
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.
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’s not all bad news at Bonn – with low carbon precincts, living infrastructure and urban networks, cities are leading the charge against climate change.
