Clean energy and jobs

Earth Wise ·

2025/10/30

America’s clean energy industry is unquestionably under attack by the Trump administration. The administration is blocking renewable energy projects on federal lands, slashing clean tech tax credits, and putting in place new regulatory hurdles for solar and wind power and electric vehicles. During the first half of the year, businesses cancelled $22 billion worth of […]

Insect declines in remote regions

Earth Wise ·

2025/10/29

Insects play a crucial role in sustaining life on Earth. They pollinate plants, recycle nutrients, and form the foundation of food webs in both terrestrial and freshwater ecosystems. Without insects, the rich biodiversity that supports our planet would not exist. However, global studies show a widespread decline in both insect abundance and diversity. According to […]

Fossil fuel producing nations ignoring climate goals

Earth Wise ·

2025/10/28

The Paris Climate Agreement has the primary goal of limiting global average temperature rise to well below 2 degrees Celsius and preferably 1.5 degrees above pre-industrial levels. Meeting this goal involves reaching global net-zero greenhouse gas emissions in the second half of the century. Doing so requires the substantial adoption of renewable energy sources to […]

Celebrity chefs and forever chemicals

Earth Wise ·

2025/10/22

Per- and Polyfluoroalkyl Substances – better known as PFAS – are a type of human-made chemicals that are found in a wide range of consumer and industrial products. They don’t break down in the environment or in the human body, so they are often called forever chemicals. They can contaminate drinking water sources and can […]

AI and the appetite for natural gas

Earth Wise ·

2025/10/20

A recent survey of the plans of U.S. electricity utilities for meeting projected future demand indicates that they are looking to build twice as much natural gas capacity as they had anticipated just 18 months earlier. The reason? Data centers. These warehouses full of computers that form the backbone of the internet are multiplying rapidly […]

2025/10/15

A company called Eco Wave Power has launched the first U.S. wave energy project in the Port of Los Angeles. The system captures the motion of ocean waves to generate renewable electricity. The Eco Wave Power system harnesses hydraulic energy with floaters installed near the shore on existing structures like breakwaters, piers, and jetties. The […]

Biosphere integrity

Earth Wise ·

2025/10/14

Civilization has an enormous need to utilize the biosphere, that is, the regions of the surface, atmosphere, and bodies of water of the earth occupied by living organisms. The biosphere supplies us with food, raw materials, and increasingly, climate protection. A study by two European universities looked at functional biosphere integrity, which is essentially the […]

The U.N. meets about geoengineering

Earth Wise ·

2025/10/09

Geoengineering refers to a wide range of mechanical or chemical methods aimed at deliberately changing the global climate system. It includes a number of unproven concepts, one of which is intentionally polluting the upper atmosphere with thousands of tons of artificial particles such as chemical sprays or mineral dust. This is referred to as solar […]

Tree plantings and climate impact

Earth Wise ·

2025/10/01

Planting trees is a key strategy in the fight against climate change. Trees absorb carbon dioxide, regulate temperature, support biodiversity, and improve air and water quality, offering benefits that extend well beyond their boundaries. But according to a new study by researchers from University of California – Riverside, where those trees are planted makes a […]

Migratory bison in Yellowstone

Earth Wise ·

2025/09/30

Tens of millions of bison once migrated across the United States in enormous herds; tribal oral histories speak of it taking days for an entire herd to pass by. These herds shaped the landscape and performed many ecosystem functions. By the 1890s, the bison population had plummeted to fewer than 1,000 individuals. Since then, dedicated […]

Ocean acidification and sharks

Earth Wise ·

2025/09/26

Carbon dioxide emissions from human activities are altering the chemistry of oceans. As more CO2 is released into the atmosphere, a significant portion of it is absorbed by seawater. This reduces the ocean’s pH, driving greater acidity, and disrupts marine ecosystems – a process known as ocean acidification. The acidifying oceans pose problems for many […]

Trying to replace neonics

Earth Wise ·

2025/09/18

Neonicotinoids – often called neonics – are a class of insecticides that are among the most widely used in agriculture. They are neuro-active, meaning that they affect the central nervous system of insects, killing or harming a wide variety of both target and non-target insects. They are often applied to seeds before planting as a […]

Supermarket bargains and food waste

Earth Wise ·

2025/09/03

Food waste is a major global problem. The UN estimates that one third of all food goes to waste. Apart from the fact that this is happening in a world where many people don’t have enough to eat, food waste is both an economic and a climate problem. Researchers from the University of Copenhagen and […]

Recycling solar panels

Earth Wise ·

2025/09/02

The use of solar energy has been growing by leaps and bounds in recent years. It is the fastest growing source of energy in the U.S. Solar panels have a useful life of about 25 to 30 years and there are growing numbers that have been around that long. They contain valuable materials, including silver, […]

Air pollution and human health

Earth Wise ·

2025/09/01

Climate change is making air quality worse in many parts of the world. Rising temperatures increase ground-level ozone, and more frequent wildfires release harmful smoke and particulates into the air. These changes, combined with ongoing pollution from sources like vehicle exhaust and industrial emissions, lead to longer and more intense episodes of unhealthy air. A […]

Reducing emissions from ocean shipping

Earth Wise ·

2025/08/13

Ocean shipping is a significant contributor to global carbon emissions, accounting for about 3% of the total. It is a key part of international trade, moving goods like electronics, automobiles, and oil. It relies on fossil fuels, and, without significant changes, shipping’s emissions could more than double by 2050. Ocean shipping is one of the […]

2025/08/12

Honeybees are a critical resource for American agriculture. The western honeybee, Apis mellifera, pollinates more than 130 types of nuts, fruits, and vegetables, adding up to $15 billion worth of crops every year. Honeybee health has been harmed by a combination of factors: weather extremes, habitat loss, pesticides, and disease. One of the biggest problems […]

2025/08/11

Hotter and drier conditions driven by climate change are leading to an increasing number of wildfires in North America and around the world. The damage wildfires cause – to forests, homes, and communities – is well-known. But long after the flames are gone, the effects can linger, especially in rivers and streams, where water quality […]

Shrinking coal and the gas trap

Earth Wise ·

2025/08/08

An important part of the 2015 Paris Climate Agreement is reducing the use of coal to produce electricity. Coal is the dirtiest fuel in common use and not burning it is a way to greatly reduce emissions. Ten years later, coal consumption around the world has decreased dramatically. The most convenient alternative to coal is […]
