Climate explained: how much of the world’s energy comes from fossil fuels and could we replace it all with renewables?
How are fossil fuels formed, why do they release carbon dioxide and how much of the world’s energy do they provide? And what are the renewable energy sources that could replace fossil fuels?
Fossil fuels were formed over millions of years from the remains of plants and animals trapped in ...
Is the Weather Actually Becoming More Extreme?
From 2016 to 2019, the world saw record-breaking heat waves, rampant wildfires, and the longest run of category 5 tropical cyclones on record. The number of extreme weather events has been increasing for the last 40 years, and current predictions suggest that trend will continue. So, is the increase...
We found methane-eating bacteria living in a common Australian tree. It could be a game changer for curbing greenhouse gases

Trees are the Earth’s lungs – it’s well understood they drawdown and lock up vast amounts of carbon dioxide from the atmosphere. But emerging research is showing trees can also emit methane, and it’s currently unknown just how much.
This could be a major problem, given met...
Cows fed small amount of seaweed burp 86 per cent less methane in trial
Feeding cattle a small amount of a seaweed species found in Australia has been shown to reduce their methane emissions by up to 86 per cent.
Key points:
Red seaweed contains a compound that can reduce the production of methane
Proponents say it could be the equivalent of rem...
Climate change pushed ocean temperatures to record high in 2020, study finds
The world's oceans absorbed 20 sextillion joules of heat due to climate change in 2020 and warmed to record levels, a study has found.
Key points:
Last year the world's oceans absorbed 20 zettajoules of heat
Higher ocean temperatures can lead to an increase in extreme weather
Seas are w...
ABC News: Our latest climate report card is here, and it’s not like we didn’t see it coming

Aussie invention could save old coal stations by running them on zero-emissions ‘Lego’ blocks
As climate change worsens, the future of fossil fuel jobs and infrastructure is uncertain. But a new energy storage technology invented in Australia could enable coal-fired power stations to run entirely emissions-free.
The novel material, called miscibility gap alloy (MGA), stores energy in the fo...
Just how hot will it get this century? Latest climate models suggest it could be worse than we thought
Climate scientists use mathematical models to project the Earth’s future under a warming world, but a group of the latest models have included unexpectedly high values for a measure called “climate sensitivity”.
Climate sensitivity refers to the relationship between changes in carbon dioxide ...
