<p>Cities can reduce environmental pressures when designed effectively. Dense urban areas generally require less land, reduce transport distances, and can support more efficient public infrastructure. A well-designed city can often have a lower per-capita environmental footprint than sprawling suburban development. The challenge lies in how cities grow. <span class="contextmenu emphasis CaptionCredit">Picture: iStock</span>

Couple goals: Can economic growth finally go green?

Researchers have found that many urban economies are continuing to grow while fossil-fuel pollution declines, meaning some cities are beginning to 'consciously uncouple' economic growth from fossil-fuel dependence

Place names on maps are not fixed truths. They are human decisions, shaped by language, power and, quite often, misunderstanding

A monopoly win isn't always good — what happens when one species takes over

Snake Island, Christmas Island, and Ireland's Saltee Islands, all show what happens when ecological balance tips and a single organism becomes just a little too successful

Why are Irish communities seeing more flooding and several 'one-in-100-year' floods?

Why are Irish communities seeing more flooding and several 'one-in-100-year' floods?

A one-in-100-year flood does not mean a flood that happens once a century. It means a flood with a 1% chance of occurring in any given year. Two such floods can occur in back-to-back years, or several can occur in a single decade

Written on the walls: what lichens tell us about our environment

Written on the walls: what lichens tell us about our environment

Lichens have no roots, no waxy leaves and no way to filter what they absorb. Everything they take in comes directly from the atmosphere so they are extraordinarily sensitive to air quality. For more than a century, scientists have used lichens to track pollution

The invisible carbon in Ireland’s waters

Dissolved organic carbon may be one of the most underestimated pressures on Irish waters. About 20% of our land area is covered by peat and peaty soils, which are among the most carbon-rich ecosystems on Earth. That makes Ireland uniquely vulnerable to large losses of carbon from land to water

Cold enough to remember

Cold enough to remember

Ireland has lived through colder climates than this, and what stands out in hindsight is not collapse, but continuity. During the Little Ice Age (from roughly the 14th century to the mid-19th century) people adapted to altered seasons and unreliable weather without knowing they were living through a climatic shift

Christmas pre-tinsel: when plants — and robins — ran the show

Strip Christmas of its baubles, batteries and Amazon deliveries, and what you’re left with is, at heart, a festival of plants. Trees dragged indoors. Mistletoe hung from the ceiling. Berries admired but (wisely) not eaten.

Curious hedgehog in the grass

A pest or a prince — is it all down to postcodes?

The conservation–invasion paradox is when a species is endangered where it evolved but causes havoc where humans introduced it. So why can't we just bring unwanted animals to where they're wanted?

Michelle McKeown: The weather tug-of-war that shapes our winters

Understanding the North Atlantic Oscillation won’t stop Irish winters being chaotic, but it helps explain why they sometimes fall into familiar rhythms. And it reminds us that, while climate change is gradually reshaping global systems, natural variability still has plenty to say

Why early-warning systems matter more than ever

Long before sensors and satellites, people used whatever tools they had to read the world around them. In fact, the earliest warning systems were rooted in observation, culture and instinct — but sensors, algorithms and automated texts are now being employed in places such as Midleton in Cork

Phosphate: the world’s most under-appreciated resource

I am almost done!

Rake expectations: should we be picking up leaves at all?

Leaves aren't litter — they’re the forest’s own recycling system, a slow-release nutrient pack designed to feed soil life and shelter small creatures through the colder months. When they decompose, they release essential nutrients, improve soil structure, and even help lock away a little carbon

Drowning nations: Kiribati and the South Pacific’s fight for survival

If we fail to meet our own 2030 climate targets, if we continue to expand high-emission sectors, then our solidarity with Kiribati is nothing more than rhetoric.
