Peatlands worldwide are running short of water, and the amount of greenhouse gases this could set loose would be devastating for our efforts to curb climate change.
Research shows people don't take politicians seriously on climate change if they don't seem fully committed.
Climate change science dominated by knowledge produced in the global North cannot address the particular challenges faced by those living in the global South.
If the G7 is serious about stopping global warming, it could start by acknowledging who and what is causing it.
A complete switch to biofuels is neither feasible nor desirable, but they could replace some fossil fuels in transport and heating. If biofuels are produced from waste products, that's even better.
For phascogales, tree hollows are getting harder to find. I venture into forests and study how well artificial hollows made with chainsaws can replace them.
Scientists studied charcoal layers in the sediment of lake beds across the Rockies to track fires over time. They found increasing fire activity as the climate warmed.
Heat pumps are the technology of choice for heating and cooling buildings more efficiently and with fewer carbon emissions than furnaces and air conditioning.
Scott Morrison may have found the meeting of the leaders of the world's liberal democracies that aligning himself so closely with former US President Donald Trump was not the most prudent course.
One cold winter doesn't negate more than a century of global warming. We need the political leadership to set the world on a safer path. Ill-informed tweets by government senators won't help.
Ancient climate change doomed the monk seals that lived in Australian waters millions of years ago.
Renewables form an ever-greater share of the electricity mix. But elsewhere in the energy sector – in transport, industry and buildings – emissions reduction is very slow.
Governments must ensure that transport infrastructure is developed with the ability to cope with current and future climatic shifts.
Rhetoric is hardening, but government policies still honour the special relationship with fossil fuels.
Countries that industrialised early will still have a massive 'carbon debt' to repay.
A recently released schools policy guide has been receiving some criticism. Reports suggest it instructs teachers to not use terms like "boys and girls", for instance. This is not entirely correct.
In Lough Hyne's shallows, animals and plants thrive that would otherwise be found in the ocean's depths.
New research looked at wave conditions over the past 40 years, and found wave power has increased since at least the 1980s, mostly in the Southern Hemisphere.
There are significant gaps in what teachers in Ghana know about ozone depletion and climate change, even though these subjects are in the science curriculum.
Climate migrants don’t fit neatly into the legal definitions of refugee or migrant, and that can leave them in limbo. The Biden administration is debating how to identify and help them.
