Air pollution is the second-largest risk factor for early death globally. Traditionally, our response has focused on reducing the levels of pollution people breathe, but this is only part of the story.
We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.
"A more decentralized energy system, with a growing share of renewables and more market players, is structurally more resilient. Countries that invested in the energy transition are weathering this crisis with less economic damage, as they boost energy security, resilience and competitiveness."
Checking your equipment once a month helps catch small issues before they turn into expensive repairs. A routine keeps everything running smoothly and extends the life of the hardware. Managers should create a simple checklist for their maintenance staff to follow.
Heritage is usually catalogued by what can be drawn, not by what changed temperature. In heat, buildings are learned first through skin, only later through sight. Generations learn, through their bodies, what works. Shade reduces glare and radiant heat. Air movement shifts perception by several degrees. Thick walls slow temperature swings.
"So whenever people think about hot weather, they always talk about the temperature," he says. "There's two issues with that. First of all, most people don't realise that the temperature is measured in the shade. So if you're in direct solar radiation, the amount of heat stress you're exposed to is much greater as it will stress your body out a lot more."
In Indra's Net of pearls and jewels, every gem reflects every other, a shimmering image of interdependence. This ancient Vedic metaphor for connection across the cosmos also illuminates what the environmental philosopher Glenn Albrecht first proposed in 2014as 'theSymbiocene': the era after the Anthropocene, in which human technologies take their cues from living systems and work in partnership rather than through dominance.
Photovoltaic (PV) solar energy represents a modular technology that can be manufactured in large-scale facilities, generating economies of scale, while also being adaptable to small-scale applications. From residential rooftop systems to large-scale power generation installations, photovoltaic solar energy has established itself as a cost-effective option for electricity production in many countries around the world.
Spaces of light and darkness are conceived to enhance circulation and spatial directionality, as well as to highlight the colors, textures, and forms of specific architectural elements. That said, the impact of natural light on building facades reveals the need to develop strategies that support energy savings, improve the thermal and visual comfort of interior spaces, and promote the reduction of carbon emissions.
From the large industrial roofs and galleries of the 19th century to the contemporary atriums of museums and public buildings, glass has been a recurring material in shaping large and monumental interior spaces. More than a technological or engineering solution, these horizontal glazed planes introduce a distinct luminous quality: light that comes from above. Unlike lateral daylight entering through façades, zenithal light is more evenly distributed, reduces harsh shadows, and lends spaces a sense of continuity and openness that is difficult to achieve otherwise.
Subzero temperatures don't pose a problem for heat pumps. The refrigerants used in the heat exchanger, which transfers heat from outside a building to inside, have an extremely low boiling point below minus 40 C. That means even when it's very cold, a heat pump can absorb ambient heat from the outside air and use it to warm a building.
When the category-5 storm Hurricane Melissa struck Jamaica in October, its path crossed communities that had varying levels of preparedness. Many with maintained coastal protections, upgraded drainage and reliable early-warning systems had power and water restored in days. Others were immobilized for weeks.
