Rivers & Oceans 'A completely new reality': Bolder measures are needed to prevent extreme water shortages in cities like Phoenix and Las Vegas that depend on the Colorado River Climate change ...

As humans burn fossil fuels and pump carbon dioxide into the atmosphere, we are heating up the planet. But there is another alarming impact of this climate pollution: it may be changing the chemistry ...

Bubbles in a 3-million-year-old ice core have allowed researchers to measure gases in the atmosphere during the late Pliocene for the first time. This epoch, when global temperatures are thought to ...

Climate change is one of the most pressing global challenges in the present times. Increasing carbon dioxide (CO 2) concentrations in the atmosphere are a major factor contributing to this phenomenon.

Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue.

Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring ...

There is widespread recognition that efforts to meet global climate targets cannot be met by curbing new carbon dioxide emissions alone and will also require removing carbon from the atmosphere at ...

PCWorld explains how to create an affordable CO2 air quality monitor using a Raspberry Pi and MH-Z19C sensor for under $40. This DIY project helps monitor indoor air quality since high CO2 levels ...

Natural biological systems cannot efficiently convert waste CO₂ or its derivatives into useful building-block chemicals at a scale that can keep pace with rising atmospheric carbon. Engineer a fully ...

China has launched the world’s first carbon dioxide–based power generator, using supercritical CO2 instead of steam to produce electricity with over 50% efficiency. The system harnesses industrial ...

When two people book the same flight, they can get wildly different carbon footprints from online calculators. Many carbon calculators leave out big chunks of climate impact or rely on oversimplified ...
