To achieve goals for climate and economic growth," negative emissions
technologies"(NETs) that remove and sequester carbon dioxide from the air will need to play …

A hidden carbon cycle exists inside Earth. Every year, megatons of carbon disappear into
subduction zones, affecting atmospheric carbon dioxide and oxygen over Earth's history …

The Perseverance rover landed in Jezero crater, Mars, to investigate ancient lake and river
deposits. We report observations of the crater floor, below the crater's sedimentary delta …

Carbon fluxes in subduction zones can be better constrained by including new estimates of
carbon concentration in subducting mantle peridotites, consideration of carbonate solubility …

Since the Industrial Revolution, anthropogenic carbon dioxide (CO2) emissions have grown
exponentially, accumulating in the atmosphere and leading to global warming. According to …

Maintaining global warming well below 2° C, as stipulated in the Paris Agreement, will
require a complete overhaul of the world energy system. Hydrogen is considered to be a key …

To avoid dangerous climate change, new technologies must remove billions of tonnes of
CO2 from the atmosphere every year by mid-century. Here we detail a land-based …

Chemical weathering is an integral part of both the rock and carbon cycles and is being
affected by changes in land use, particularly as a result of agricultural practices such as …

The signals are everywhere that our planet is experiencing significant climate change. It is
clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases …

Beyond its role as an energy vector, a growing number of natural hydrogen sources and
reservoirs are being discovered all over the globe, which could represent a clean energy …
