As global temperatures rise due to increased greenhouse gas emissions, communities around the world face more frequent and intense heatwaves, droughts, and extreme weather events. These growing climate pressures not only strain infrastructure and natural resources, but also play a critical role in shaping where people live.  Recent projections from the First Street Foundation, which […]
Atoll islands are made from sediment produced by corals, clams, snails, and varieties of algae that secrete carbonate.  Under the right conditions, over time, fragments of coral skeletons, shells, and other sediments made by marine life are piled up by waves.  Eventually, islands are formed – some large and some small.  Atoll islands are home […]
Worldwide investment in renewable energy topped $2 trillion in 2024.  For Climate Solutions Week, we wanted to highlight some amazing projects around the world that showcase innovative technology, ambitious scale, and the commitment to a cleaner and sustainable future. In Morocco, the Noor Solar Power Station is a huge concentrated solar power facility that generates […]
Nature is often seen as a victim of climate change, but it’s also one of the most powerful tools we have to fight it. Natural ecosystems, such as forests, wetlands, grasslands, oceans, and soils, absorb and store massive amounts of carbon dioxide. These ecosystems not only help reduce the concentration of greenhouse gases in the […]

Feeding the future
Climate change is already affecting the yields of major staple crops around the world, and researchers warn that the impacts will become more severe over time. Rising temperatures, shifting rainfall patterns, and more frequent extreme weather events are disrupting growing seasons and reducing agricultural productivity. Addressing these growing threats requires rethinking how we grow, distribute, […]
The Human Genome Project is one of the greatest scientific feats in history.  It was launched in 1990 and completed in 2003.  The international group of researchers wanted to comprehensively study all of the DNA – the genome – from a select set of organisms, foremost of which being that of human beings.  The results […]
Over the first several months of this year, hundreds of sea lions, dolphins, and seabirds have fallen ill or died after eating sardines or anchovies that had been feeding on an algal bloom along the California coast since winter.  The biotoxin in the algae accumulates in the feeder fish. Two cases of whales dying from […]

Solar on farmland
New studies have found that devoting a small percentage of U.S. farmland to producing solar power would benefit both the country’s energy system and its farmers. Currently, about 46,000 square miles of farmland – about the area of Pennsylvania – is being used to grow corn to make ethanol.  One study looked at the impact […]
Beginning in 2013, a mysterious disease associated with a marine heatwave decimated the population of sunflower sea stars.  Those huge, colorful 24-armed starfish thrived along the Pacific Coast between Alaska and Baja California.  But in fairly short order, nearly six billion of the creatures perished, amounting to 94% of the global population.  California lost 99% […]
According to the American Lung Association’s annual State of the Air report, at least 156 million Americans – 46% of the population – live with unsafe levels of ozone, particulate pollution, or both. The report analyzed ozone and particulate pollution levels between 2021 and 2023, during which the worst wildfire season on record took place […]
