Sea levels are rising and ocean warming is responsible for the bulk of that rise.  As water heats up, it expands, which drives up sea levels.  But on top of that, global warming is melting the polar ice sheets, and that is leading to about a quarter of the world’s sea level rise. So far, […]

Not long ago, electric cars were a rarity.  Ten years ago, annual global sales of EVs were only a few hundred thousand.  As of today, globally, still less than one percent of all the cars on the road are electric.  But that is changing rapidly. In fact, electric vehicles are expected to capture nearly 20% […]

Greenhouse gases continue to rise

Greenhouse Gases Continue To Rise | Earth Wise

Reducing the amount of carbon dioxide entering the atmosphere means either shutting down emission sources (primarily curbing the use of fossil fuels) or capturing the CO2 as it is emitted.  Capturing carbon dioxide from smokestacks and other point sources with high concentrations is relatively efficient and can make economic sense.  Removing it from the air, […]
