Cooling Earth's climate with commercial aircraft may be possible

A groundbreaking study from University College London finds that commercial aircraft may already be capable of performing climate-cooling aerosol injections over polar regions. While less efficient than tropical, high-altitude deployments, this method could offer a faster and cheaper stopgap in the race to cool Earth—though serious equity and environmental challenges remain.

Sectarian clashes near Damascus leave 13 dead as tensions rise in Druze town

Sectarian violence in Jaramana, near Damascus, has left at least 13 dead after a voice recording allegedly insulting the Prophet Mohammad sparked Sunni-Druze tensions. The clash highlights deep-seated fears among minority groups and growing instability under Syria’s new Islamist-led government.

UNDP launches global sustainable finance office in Dublin with €7.5M Irish support

Why is South Africa rising? The answer lies in a drying Earth

New research reveals that South Africa’s land is rising—not because of deep Earth forces, but due to drought-driven water loss. GNSS data shows that as groundwater disappears, the land rebounds upward. This shift, tracked precisely by satellite and GPS networks, could reshape how we monitor water stress in the climate era.

Nitrous Oxide: The Unseen Climate Threat Lurking in Our Farmlands

The Most Underrated Climate Solution Is Already in Our Streets

Urban flooding, heatwaves, and water pollution are intensifying—but the solution may already be growing at street level. As cities search for ways to build climate resilience, bioswales offer a powerful, often overlooked alternative to conventional stormwater systems. But are we truly using them to their full potential? In this editorial, we explore how bioswales work—not just as green strips in the landscape, but as living infrastructure that filters pollutants, reduces runoff, recharges groundwater, and cools the urban environment. Drawing insights from global case studies and city-level performance data, we uncover why bioswales remain underutilized, and how superficial adoption risks turning a high-impact solution into a decorative gesture. Like green certifications in finance, poorly implemented bioswales can miss the mark when intent outweighs function. We outline what credible bioswale design looks like, why maintenance and monitoring matter, and how these systems can redefine what it means to be a climate-ready city. For urban planners, policy makers, ESG professionals, and sustainability advocates, this article offers a grounded framework to assess green infrastructure—not by appearance, but by impact. Because when it comes to building resilient cities, green must go beyond good intentions. It must work.

Green Isn’t Always Clean: The Dark Side of ESG Certifications

Not all that’s labeled “green” is truly sustainable. As ESG certifications and ratings flood the market, many finance and sustainability professionals are beginning to ask tough questions. Why do some green bonds fund fossil fuel-linked projects? How can a company score high on ESG while harming the environment? In this editorial, we explore how current frameworks and certifications often miss the mark—and how that gap fuels widespread greenwashing. Through global examples—from the EU Taxonomy to MSCI ratings to LEED-certified buildings—we unpack where the system breaks down, and what credible sustainability really looks like. If you’re navigating ESG decisions, this article offers a practical lens to assess labels more critically and avoid being misled by appearances.

Ocean Temperatures Are Rising Faster Than Expected — And Likely to Accelerate

Ocean surface temperatures are now rising four times faster than they were in the late 1980s, driven primarily by a greenhouse gas–induced energy imbalance. This acceleration fuels stronger storms, rising sea levels, and disrupted ecosystems. Long-term satellite data confirms that natural cycles alone can’t explain the trend. Scientists emphasize the urgent need for improved monitoring and global emissions cuts—because the ocean’s heat uptake is no longer just a climate signal, it’s a planetary warning.
