Renewable energy is changing more than the way electricity is generated. It is reshaping how homes, businesses, communities and entire countries think about energy security, cost, resilience and environmental sustainability. The essentials at a glance: In simple terms: renewable energy turns resources that nature continually replenishes — sunlight, wind, water, biological material and heat from…
Climate change does not mean that every flood, heatwave, hurricane or unusually cold day can simply be blamed on global warming. The relationship is more nuanced — and considerably more interesting. Human-caused climate change is altering the background conditions in which weather develops. A warmer atmosphere can hold more moisture, oceans are accumulating heat, sea…
Sea levels are rising primarily because human-caused climate change is warming the planet. A warmer ocean expands, while glaciers and the Greenland and Antarctic ice sheets lose land-based ice that ultimately adds water to the ocean. Scientists track these changes using tide gauges, satellites and other observations. However, global mean sea level and the sea…
Rising temperatures are doing far more than making summer afternoons feel hotter. As the climate warms, the consequences spread through weather systems, human health, agriculture, wildlife, water supplies, infrastructure and the oceans. In the UK, hotter summers and more frequent periods of extreme heat sit alongside other climate risks, including drought, heavy rainfall and flooding.…
Greenhouse gases are naturally present in Earth’s atmosphere and play an essential role in keeping the planet warm enough for life. The problem arises when human activities — particularly burning fossil fuels, deforestation, agriculture and industrial processes — increase their atmospheric concentrations. Carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) are among the most…
Forests are one of the planet’s natural climate regulators. Trees absorb carbon dioxide (CO₂) from the atmosphere, store carbon in their trunks, branches, roots and surrounding soils, and influence rainfall and local temperatures. Deforestation interferes with all of these processes at once. Clearing or burning forests can release stored carbon while removing trees that would…
Human activity has become a major influence on Earth’s climate system. The biggest driver is the release of greenhouse gases from burning fossil fuels such as coal, oil and natural gas. Energy generation, transport, manufacturing, agriculture, food production, deforestation, buildings and waste all contribute in different ways. The basic chain is relatively straightforward: Human activities…
Upcycling takes materials, products and by-products that might otherwise be discarded and finds ways to preserve — or increase — their usefulness and value. Unlike conventional recycling, which often breaks materials down before turning them into something new, upcycling can extend product life through creative reuse, repair, redesign and transformation. Its potential stretches far beyond…
Minimalism and sustainability meet at a surprisingly simple idea: consume with intention. Buying fewer things, choosing durable products, reusing what already exists and resisting unnecessary purchases can reduce waste and demand for natural resources. A minimalist lifestyle isn’t about owning almost nothing. It’s about deciding what genuinely adds value to your life—and becoming more conscious…
Sustainable consumption is about getting more value and wellbeing from the resources we use while reducing waste, pollution and unnecessary demand for new materials. It can mean buying less, choosing durable products, repairing rather than replacing, reusing what already exists, reducing food waste and considering how goods were produced. Individual choices alone won’t solve climate…
