Light pollution has obscured the night sky for nearly 3 billion people, but it’s possible to bring back the Milky Way by making smarter lighting choices. Shielding streetlights, using warm-colored lighting, and dimming unnecessary lights can reduce light pollution by up to 30%, as shown in cities like Canberra. These measures help save energy and restore our connection to the stars, making the Milky Way visible from major cities once again.

Canada’s June 2024 heat wave broke temperature records across the country, with new findings confirming its link to human-caused climate change. The ECCC’s rapid attribution analysis revealed that climate change made this extreme heat event significantly more likely. Understanding these connections is vital for improving adaptation efforts and preparing for more frequent extreme weather events, especially as the impacts on vulnerable populations, including the elderly, grow more severe.

An extreme heatwave in India and Pakistan has left more than a billion people in one of the most densely populated parts of the world facing temperatures well above 40?. Although this has not broken all-time records for the regions, the hottest part of the year is yet to come.

Sometimes realisation comes in a blinding flash. Blurred outlines snap into shape and suddenly it all makes sense. Underneath such revelations is typically a much slower-dawning process.

A “super full moon” is coming, and coastal cities like Miami know that means one thing: a heightened risk of tidal flooding.

The world loves coffee. More precisely, it loves arabica coffee. From the smell of its freshly ground beans through to the very last sip, arabica is a sensory delight.

As a species, humans are wired to collaborate. That’s why lockdowns and remote work have felt difficult for many of us during the COVID-19 pandemic.

Wood is an ancient material humans have been using for millions of years, for the construction of housing, ships and as a source of fuel for burning. It’s also a renewable source, and one way to capture excess carbon dioxide from the Earth’s atmosphere.

As the climate changes, floods and extreme rainfall events will become more intense. In many cases, the most disadvantaged people are at highest risk from floods and least able to bounce back when their homes and businesses are inundated.

The bleak history of whaling pushed many species to the brink of extinction, even in the remote waters of the north and south poles. Over 1.3 million whales were killed in just 70 years around Antarctica alone.

Producers and retailers of everything from toilet paper to homes want you to believe that their product is “green”. More are “greenwashing” their products. Greenwashing is the misleading claims of environmental benefits...

Creative destruction “is the essential fact about capitalism”, wrote the great Austrian economist Joseph Schumpeter in 1942. 

Global emissions are expected to decline by about 7% in 2020 (or 2.4 billion tonnes of carbon dioxide) compared to 2019 — an unprecedented drop due to the slowdown in economic activity associated with the COVID-19 pandemic.

Climate change is now climate crisis and a climate sceptic now a climate denier, according to the recently updated style guide of The Guardian news organisation.

With global travel curtailed during the COVID-19 pandemic, many people are finding comfort in planning future trips.

The gold standard of research in science is the randomised controlled trial. The COVID-19 restrictions may at times seem random and most certainly feel like a trial. But are they controlled enough to learn from?

Australia doesn’t yet export renewable energy. But the writing is on the wall: demand for Australia’s fossil fuel exports is likely to dwindle soon, and we must replace it at massive scale.

As California contends with its worst wildfire season in history, it’s more evident than ever that land management practices in the state’s forested mountains need major changes.

I am wondering about the climate impact of vegan meat versus beef. How does a highly processed patty compare to butchered beef? How does agriculture of soy (if this is the ingredient) compare to grazing of beef?

Demand for fossil fuels collapsed during the COVID-19 pandemic as lockdown measures were introduced. In the second quarter of 2020,

Summer temperatures in Chicago normally peak in the low 80s, but in mid-July 1995 they topped 100 F with excessive humidity for three days straight.

It’s an uncomfortable but inescapable historic fact that great pandemics often bring about social reform.

How do you respond to a crisis? It’s obvious that the response to the COVID-19 pandemic has been dramatically different to anything provoked by repeated scientific warnings about climate change.
