Explaining environmentalism to a taxi driver, in three miles or less

I'm in a taxi, and after the obligatory nod to the weather and the state of Dublin’s one-way systems, the driver is telling me what he thinks about my choice of career. “Environmentalists: you’re just like the taxman, making everyone’s lives awkward.” He has a point. Environmentalists are often accused of being anti-progress or anti-development,

Sometimes it’s not good to be green

The good news is global and local. Keeping inland lakes from turning green means less greenhouse gases entering the atmosphere and contributing to climate change. Healthy drinking water, fishing and recreation opportunities are also increased when waters are not green. What's wrong with being green? Toxins released by algal blooms can ruin drinking water. When

National service for the environment could be the key to fighting climate change

The school climate strikes show that young people want to fight climate change, but their enthusiasm for collective action is largely untapped. A volunteer conservation army could mobilise their talent and passion by channelling it into work to restore ecosystems. The Green New Deal – endorsed by US Congresswoman Alexandria Ocasio-Cortez and numerous presidential candidates

Turn off a light, save a life

We all know that turning off lights and buying energy-efficient appliances affects our financial bottom line. Now, according to a new study by University of Wisconsin-Madison researchers, we know that saving energy also saves lives and even more money for consumers by alleviating the costs of adverse health effects attributed to air pollution. Writing this

India pushes for greater uptake of electric mobility

In the gold rush for global domination of the electric mobility market, India has thrown its hat into the ring. The Modi-led government announced last month that it would offer US$1.4 billion in subsidies for both buyers and manufacturers of electric vehicles and impose higher import tariffs to spur domestic companies to build vehicles.

Wales: ‘Radical’ plan could deliver 100 per cent renewable power by 2035

Wales could shift to 100 per cent renewable electricity by 2035, creating over 20,000 jobs and delivering a £7.4bn economic boost for the country's economy. That is the headline conclusion from a new report released last week by the Institute of Welsh Affairs (IWA) as part of the think tank's Re-Energising Wales project, which argues

The answer to the UK’s renewable energy future is blowing in the wind

Auctions for new capacity held in 2017 resulted in deals at half the price of those signed just two years prior, while we are seeing a steady drumbeat of new records relating to clean power production. Just last month, the world’s largest offshore wind farm began generating power. Anchored to the seabed 75 miles off

Rainfall changes for key crops predicted

Even if humans radically reduce greenhouse gas emissions soon, important crop-growing regions of the world can expect changes to rainfall patterns by 2040. In fact, some regions are already experiencing new climatic regimes compared with just a generation ago.

Tectonics in the tropics trigger Earth’s ice ages

Over the last 540 million years, the Earth has weathered three major ice ages -- periods during which global temperatures plummeted, producing extensive ice sheets and glaciers that have stretched beyond the polar caps. Now scientists at MIT, the University of California at Santa Barbara, and the University of California at Berkeley have identified the
