Supermarkets and farms have acted to ensure they discard fewer "ugly" and "wonky" fruit and vegetables. However, the bulk of the problem lies with households.
Weather-related catastrophic events have cost Canadians more than $17 billion in the past decade. That only stands to grow, unless building codes change to make homes more resilient.
With heatwaves, droughts and fires all on the rise, the federal government is urged to merge its separate strategies on disaster resilience and climate readiness.
New and stronger evidence confirms global warming will mean more intense and frequent floods, heatwaves and droughts.
Marine heatwaves, like their land counterparts, are growing hotter and longer. Sea species in southeastern Australia, southeast Asia, northwestern Africa, Europe and eastern Canada are most at risk.
Natural gas supplies are growing, but so are other markets for it besides power generation.
Australian wheat growers need to boost yields to stay competitive in the face of climate change. They could do this by sowing earlier, but need new varieties of wheat to help them do it.
What do the recent Townsville floods and Tasmanian heatwave have in common? Both were caused by weather systems that stayed put for days or weeks on end. And global warming could worsen that trend.
The bacteria that causes melioidosis usually lives 30cm underground in clay soil but is dredged to the surface during heavy rains and floods, and can enter the body through small breaks in the skin.
We can't make it rain. But you are already helping if you don't use more water than you need. And you can talk to your parents about the planet getting warmer, because the heat makes drought worse.
A new report predicts that one-third of the ice in the Himalayas will melt, even if we contain global warming to 1.5C. So what does that mean for the flood-prone valleys below?
Everyone knows the Great Barrier Reef is in peril. But a continent away, Western Australia's Shark Bay is also threatened by marine heatwaves that could alter this World Heritage ecosystem forever.
Black Saturday in 2009 was Australia's worst bushfire tragedy. But climate projections predict more bushfire danger in the future, threatening our water supplies as well as homes.
The flood zone around Townsville extends for hundreds of kilometres, making monitoring difficult even from the air. But scientists are testing a new satellite method that can peer through the clouds.
Mass wildlife die-offs, such as those wrought by Australia's recent heatwaves, make for grim headlines. But the wider effects of extreme weather are more complex, and can be remarkably long-lasting.
Making electric grids better able to withstand extreme weather events will require teamwork from engineers, researchers and the government.
Life-threatening cold temperatures in the central US are caused by changes in wind circulation in the Arctic that bring cold air south. Climate change could make these events more frequent.
As global warming intensifies violent weather events, the most vulnerable countries affected need help to respond more effectively.
Haiti is extremely vulnerable to climate change. It is also very poor. International donors have stepped in to help the country fund climate mitigation, but is the money going where it's most needed?
Hazardous professions including agriculture and heavy engineering are already having to find ways to adapt.
