For the past two decades, a giant digital display in Manhattan’s Union Square has clocked up the accumulation of days, hours, minutes and seconds for the thousands of New Yorkers who hurry past it each day. Now, for the first time, it’s counting down: Revealing just how little time we have left to tackle the climate crisis before the planet is past a tipping point of irreversible change.

Produced by the UN Environment Programme (UNEP) and partner organization WRAP, the Food Waste Index Report 2021 reveals that between food wasted in homes, restaurants and shops, 17 per cent of all food is just dumped. Some food is also lost on farms and in supply chains, indicating that overall a third of food is never eaten.

Food waste creates more greenhouse gases than the airline industry. But there are several ways to fix that, starting with your shopping habits.

Natural gas utilities face a bleak future in a world increasingly concerned about climate change. An NPR investigation shows how they work to block local climate action and protect their business.

The promise of negative emissions is baked into most “net zero” pledges. But putting that into practice is easier said than done.

The month of December opened with good news and bad news for people concerned about the climate crisis. A climate analysis released by the independent watchdog group Climate Action Tracker said that based on promises made by Paris Climate Agreement participants, the world could limit warming to 2.1 degrees C (3.8 degrees F) by the year 2100.

With the addition of Justice Amy Coney Barrett to the U. S. Supreme Court, it doesn’t seem hyperbolic to predict that the Supreme Court will be the most anti-environmental court in the modern era.

Being a bearer of bad news is never easy. I’ve been writing and talking about climate change for decades now. Constant exposure hardens one to even the most horrific reality, and I’ve coped by acting like a jolly hangman – or at least not giving in publicly to the helplessness I sometimes feel as I relate the latest findings.

Climate deniers and opponents of aggressive climate action have long argued that governments can’t afford comprehensive measures to confront the climate crisis. The Green New Deal, for example, has been ridiculed as a “crazy, expensive mess” by the Republican Policy Committee.

Guardian readers place concern about the environment far above the coronavirus pandemic, which has dominated headlines in 2020. One month out from New Zealand’s general election and the major parties are on the campaign trail, donning high-vis jackets and face masks to visit factories, small businesses and schools around the country.

This celebrated research gives governments a reason to give climate change a low priority, but is based on spurious empirical data.

Gates said to understand the impact climate change will have, we need to "look at COVID-19 and spread the pain out over a much longer period of time."

On the inaugural Earth Day, Americans flooded streets and college campuses to channel their fears, desire, hopes and longings into their vision for a better future. All these years later, we have failed to heed their call.

The Victorian Energy Upgrades (VEU) scheme, which provides access to subsidized, energy-efficient products and services, allows Victorians to reduce their energy and gas emissions. The program also encourages investment, employment, and innovation in the industries which supply these products and services. In order to achieve the annual objective set in the Victorian legislation, large energy retailers are required to acquire and submit Victorian Energy Efficiency Certificates (VEECs).

Victorian Energy Upgrades Program (VEU) by the government of Victoria can save your money on upgrading lighting costs, reduce your energy costs and contribute to the environment. By adding electricity-saving LED light bulbs, you save up to 80 percent on your lighting costs. That's up to 16 dollars annually per globe. A national energy-saving target is set by the program which results in a variety of energy-efficient products and services for households and businesses being provided at a subsidized rate.

It’s likely that BP and other companies wouldn’t be acting to fight climate change if investor and activists weren’t demonstrating they care. As stakeholders in the U.S. public lands, we should ask no less of those who are entrusted with their management.

In today's world, where even basic facts are being distorted and disputed depending on one's partisan lens, misinformation runs rampant on social media. And there's no topic for which that is truer than the most partisan issue of all in the U.S. today: climate change. This week, a false claim about volcanoes posted on Twitter went viral. The tweet claimed that Tuesday's eruption of Mt. Merapi in Indonesia "spewed more CO2 than every car driven in history. Climate change is natural."

Are we on track for a catastrophe, or a meltdown? This somewhat gnat-straining debate has emerged around new modeling, some of which suggests that a much-dreaded “worst case scenario” of five degrees celsius of warming by 2100 is less likely than previously thought, and some of which suggests exactly the opposite.

Ever since visiting Davos for the World Economic Forum last month, Trump has been obsessed with trees. He continued going on about them at the State of the Union on Tuesday night.

Treasury Secretary Steven Mnuchin was criticized by scientists after he claimed that teenage climate activist Greta Thunberg should not criticize American fossil fuel investments until she studies economics in college.
