Earth’s magnetic field protects us from the solar wind, guiding the solar particles to the polar regions. SOHO (ESA & NASA) Climate Explained is a collaboration between The Conversation, Stuff and the New Zealand Science Media Centre to answer your questions about climate change. If you have a question you’d like […]

Yet, despite genuine achievements […]

The study is the first to measure vegetation changes across the Arctic tundra, from Alaska and Canada to Siberia, using satellite data from Landsat, a joint mission of NASA and the U.S. Geological Survey.

A research team from Caltech and the UCLA Samueli School of Engineering has demonstrated a promising way to efficiently convert carbon dioxide into ethylene — an important chemical used to produce plastics, solvents, cosmetics and other important products globally. The scientists developed nanoscale copper wires with specially shaped surfaces to […]

For that reason, monitoring […]
