Two business professors spent five years studying Walmart's ambition project to bring sustainability to its millions of budget-conscious customers – a plan that began with the birth of a granddaughter.
'Hothouse Earth' is not a sure thing – yet. Here's what you can do about it.

Heatwave deaths this summer make it clear: climate change is a severe public health threat, and those who live alone are at greatest risk.
Firefighters and volunteers battle a blaze near Loutraki in southern Greece.
From Greece, to the UK, to Japan and even Sweden, a slew of places in the Northern Hemisphere are suffering extreme heat. And the chances of extreme heat records tumbling are growing all the time.
Some fish fared better than others amid the extreme temperatures of the 2016 heatwave.

The 2016 heatwave that caused mass bleaching on the Great Barrier Reef didn't just kill corals - it also significantly changed the makeup of fish communities that call these reefs home.
As the world prevaricates over climate action, Antarctica’s future is shrouded in uncertainty.

What will Antarctica look like in 2070? Will the icy wilderness we know today survive, or will it succumb to climate change and human pressure? Our choices over the coming decade will seal its fate.
Without floating sea ice, climate-weakened ice shelves are wide open to attack by waves.

Since 1995, several ice shelves off the Antarctic Peninsula have abruptly disintegrated. A new analysis suggests that these events are triggered when ice shelves lose their buffer of floating ice.
It would be in Africa’s best interests to limit a rise in global temperature.
Keeping global warming to 1.5°C could significantly decrease the frequency of extreme climate events across Africa.
Protesting in Berlin.
Not the sort of amount you'd want to lose down the back of the sofa.
Children will be responsible for the future protection of our fragile planet. Their knowledge and engagement are critical.
Marine heatwaves can kill off species and alter ecosystems.
Marine heatwaves have had little attention until recently, but they're already having large effects.
Poor tropical nations are likely to feel the effects of climate change most acutely.
Global warming will be most noticeable where the weather doesn't normally vary much, such as the tropics. But these places are also home to many of the world's poorest and least culpable nations.
Scientists on Arctic sea ice in the Chukchi Sea, surrounded by melt ponds, July 4, 2010.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
Staghorn and tabular corals suffered mass die-offs, robbing many individual reefs of their characteristic shapes.

The 2016 bleaching event resulted in 30% mortality on the Great Barrier Reef, with many corals dying of the heat before they bleached and the loss of branching corals creating less complex reef structure.
Tesla is installing one of the world’s largest solar arrays at its Gigafactory 1 in Nevada.
Will the renewable energy transition end up creating yet more greenhouse emissions, as we ramp up the manufacture of wind turbines and solar cells? Not if their manufacture is itself powered by renewables.
Despite the climate crisis, humans have continued emitting and intensively using fossil fuels.
The climate crisis is a complex scientific problem. New systems have to be developed through democratic systemic reforms.
The increasingly bleached coral at Black Point on the Cobourg Peninsula is a worrying sign of what’s to come for other coral reefs in Australia.
Coral bleaching has struck the Northern Territory, adding urgency to the need for better national management strategies for our warming oceans.
The tale of the snow crab bears witness to the how the complexities of climate change and fights over fishing rights play out.
A heritage landscape researcher used the work of a Victorian aerial photographer to map a century of glacial loss in the Alps – and the results are staggering.
