Living in a warming world

June 13, 2025 By EarthWise Leave a Comment

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 analyzes climate risks across the United States, highlight just how significant these shifts could be. In Sacramento County, California, rising flood risks, declining air quality, and soaring insurance costs could lead to a population decline of up to 28% by 2055. The risk assessment also projects that Monmouth and Ocean counties in New Jersey could each lose more than 30% of their populations. And Fresno County, California, could see nearly half of its residents relocate due to mounting climate-related pressures.

Urban areas like cities, towns, and suburbs are particularly vulnerable to the impacts of climate change. Cities become significantly hotter due to the abundance of heat-absorbing surfaces and lack of green spaces, which intensifies heatwaves, worsens conditions for vulnerable populations, and may ultimately force some people to move.

Addressing these challenges requires a combination of climate solutions focused on both mitigation and adaptation. Solutions like expanding green infrastructure with urban parks and green roofs, and promoting sustainable development through energy-efficient buildings and transit-friendly design could all play a vital role in strengthening climate resilience.

As the planet warms, where we live – and how we live there – is rapidly being redefined.

Natural solutions for disappearing islands

June 12, 2025 By EarthWise Leave a Comment

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 to a diversity of human cultures and are important refuges for a quarter of the world’s seabirds as well as numerous nesting sea turtles and tropical plants.

Rising sea levels – the rate of which has more than doubled over the past 30 years – are a mounting challenge for atoll islands. And by the end of this century, sea level is projected to rise between 11 and 40 inches, depending on the world’s actions with regard to greenhouse gas emissions.

The ability of atoll islands to persist depends on the health of their ecosystems and the extent to which their natural processes have been disrupted by human activity. To protect the most vulnerable islands, some researchers now propose using nature-based solutions – like restoring and protecting coral reefs and native forests.

Reclaiming seabird habitat can help reefs persist and restore the resilience of atoll islands. Seabird guano washes off islands and into reefs, providing nutrients that boost coral growth and fish populations.

Nature-based solutions cannot help the most urbanized atoll islands. These islands have already irreversibly lost their natural adaptive capacity. For those places, engineered approaches such as concrete seawalls are needed.

Five amazing renewable energy projects

June 11, 2025 By EarthWise Leave a Comment

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 power for more than a million Moroccans. The facility stores some of the heat generated by the sun in molten salt so it can continue to produce power after sunset.

The Three Gorges Dam in China is the world’s largest power plant by installed capacity. The 32 turbines generate enough electricity to power millions of homes.

The Alta Wind Energy Center in California is one of the largest onshore wind farms in the world. The 600 turbines at the facility provide clean electricity for up to 450,000 homes.

The Yamakura Dam Floating Solar Project in Japan has more than 50,000 solar panels that provide electricity for about 5,000 households. The plant is located atop the surface of the Yamakura Dam reservoir and is one of the largest floating solar installations in the world.

The Hellisheiði Power Station in Iceland is one of the world’s most technologically advanced geothermal energy plants. It taps into Iceland’s volcanic geology and draws both high-pressure steam and hot water to provide both electricity and heat to thousands of local homes and businesses.

These five projects are just a sampling of the renewable energy development going on all over the world.

Nature: An important climate ally

June 10, 2025 By EarthWise Leave a Comment

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 atmosphere, but they also regulate temperatures and provide buffers against extreme weather.

One of the most effective strategies for mitigating climate change is simply protecting and restoring these natural areas. For example, mangrove forests – those coastal wetlands filled with tangled, salt-tolerant trees – sequester carbon at high rates and help protect coastal communities from storm surges and rising seas. Peatlands – another type of wetland – store more carbon than all the world’s forests combined – despite only covering 3% of Earth’s land surface. Global restoration efforts are underway, from replanting mangroves in Southeast Asia to rewetting degraded peatlands in Europe.

Creating urban green spaces like parks and community gardens, restoring forests through native tree plantings, and adopting sustainable agricultural practices like cover cropping and agroforestry are all proven to be low-cost, high-impact climate solutions.

While nature-based solutions are gaining recognition, they remain critically underfunded, according to a recent United Nations report. Closing this gap is essential to unlocking nature’s full climate potential.

Investing in nature isn’t just about preserving Earth’s natural beauty. It’s a practical strategy for building a more resilient and sustainable future.

Feeding the future

June 9, 2025 By EarthWise Leave a Comment

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, and consume food. To kick off Climate Solutions Week, we wanted to examine some solutions that could make food systems more resilient, sustainable, and adaptable to our rapidly changing environment.

One solution is Climate-Smart Agriculture, which blends traditional practices with modern techniques to boost productivity while reducing greenhouse gas emissions. Methods like zero tillage, intercropping, and crop diversification could improve soil health, conserve water, and help farms withstand climate extremes.

Expanding the production of highly nutritious and climate resilient food crops – like millet, sorghum, teff, quinoa, chickpeas, and tepary beans – will also have an important role to play. At the same time, reducing food waste through better storage, labeling, and surplus food re-use could help meet demand without increasing production pressure.

Agriculture is the largest user of freshwater globally, and climate change is intensifying water shortages. Farmers will need to transition to water-efficient farming practices, including drip irrigation, rainwater harvesting, and the reuse of treated wastewater.

Together, these solutions could help revolutionize the global food system to both feed a growing population and help protect the planet.
