Global sea surface temperatures reached record-high levels over the summer of 2023. The warmer waters were fueled by decades of human-caused climate warming and a recent boost from the natural climate phenomenon El Niño. All the added heat stressed coral reefs around Florida, Cuba, and the Bahamas, triggering bleaching watches and alerts for the area.
Corals thrive within a small range of temperatures and become stressed when water is too hot or cold. Bleaching occurs when stressed corals expel the algae that live inside them, stirpping corals of their color. Extreme bleaching can leave a reef susceptible to starvation, disease, and even death.
@nasa and other satellites help track stress on corals. Data for the animation are compiled by @noaa’s Coral Reef Watch, which blends observations from polar orbiting satellites such as the NASA-NOAA Suomi NPP, and from geostationary satellites such as GOES, with computer models.
Image Description:
This animation shows ocean waters transitioning from blue to deep red as heat built up over the summer around Florida, Cuba, and the Bahamas. The colors show accumulated heat stress, where blue means no heat stress and deep red means greater than 12 degrees Celsius of added heat over the weeks of July 1 through September 30, 2023. The landmasses are white.

The UK Government’s Carbon Budget and Growth Delivery Plan has intensified debate around sustainable construction and the need for measurable carbon reduction. The framework aims to align national industry output with carbon budget commitments and accelerate the shift toward net zero carbon buildings. Critics highlight a shortfall in immediate structural change and caution that the policy risks depending too heavily on future technology. Analysts suggest that without robust whole life carbon assessment and life cycle cost evaluation, the plan may fail to capture the full environmental impact of construction and building lifecycle performance across the sector.
Major construction firms are evaluating the implications for embodied carbon and whole life carbon calculations, particularly in infrastructure projects that dominate the UK’s emissions profile. Industry bodies continue to press for legislation mandating lifecycle assessment as part of project approvals to ensure that embodied carbon in materials and low carbon construction materials are central to delivery. Integrating circular economy principles and whole life carbon assessment into procurement processes is viewed as crucial for achieving truly sustainable construction outcomes, especially under increasing investor and public scrutiny.
The inclusion of electrification incentives within the government’s plan was welcomed by many sustainable building design specialists and contractors seeking to enhance eco-friendly construction operations. Financial support for low carbon building and energy-efficient buildings offers opportunities to apply low carbon design strategies directly on-site. Greater use of renewable building materials, green building products and low embodied carbon materials could reinforce both BREEAM and the forthcoming BREEAM v7 standards, reinforcing environmental sustainability in construction through measurable improvements in resource efficiency in construction and life cycle thinking in construction.
Policy contrasts across devolved administrations continue to shape the sector’s outlook. Scotland’s decision to defer its landfill ban underscores the need for a more coherent circular economy in construction and wider circular construction strategies. The renewal of the Just Transition Commission demonstrates continued commitment to sustainable building practices that combine decarbonising the built environment with social equity. The move highlights the relevance of environmental product declarations (EPDs) and sustainable material specification in accelerating progress toward net zero whole life carbon performance on major developments.
Research from University College London showing that wind power has saved the UK £104 billion since 2010 strengthens the industrial case for investment in green infrastructure and renewable integration. This evidence suggests that sustainable design and eco-design for buildings not only drive carbon footprint reduction but also deliver long-term life cycle cost savings. For developers seeking to achieve carbon neutral construction targets, these findings bolster arguments for end-of-life reuse in construction and scalable green construction practices. The broader message emerging from both policy direction and academic analysis is clear: the path to sustainable urban development demands precision in measurement, transparency in carbon footprint of construction data and commitment to turning sustainability strategies into quantifiable action.
