UNITED NATIONS — The global economic losses from natural disasters like earthquakes, floods, droughts and cyclones and have continued rising to reach an average of $250 billion to $300 billion annually, according to a U.N. report released Wednesday.
“Blue carbon” is a term you might be hearing more often. It refers to marine vegetation that has an inherent ability to sequester carbon and mitigate the consequences of carbon dioxide (CO2) emissions.
Vegetated coastal habitats including seagrass meadows, mangrove forests and tidal marshes were the first to be labeled as blue carbon. These marine photosynthesizers take up CO2 from the surrounding seawater and sequester carbon in the plants and the sediments below them, similar to terrestrial forests, but far more effectively. ...

A small but growing number of entrepreneurs are creating sea-farming operations that cultivate shellfish together with kelp and seaweed, a combination they contend can restore ecosystems and mitigate the impacts of ocean acidification.
Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, so has the acidity of oceans worldwide. Since pre-industrial times, the pH of the oceans has dropped from an average of 8.2 to 8.1 today. Projections of climate change estimate that by the year 2100, this number will drop further, to around 7.8 — significantly lower than any levels seen in open ocean marine communities today. ...

EV's influence on global gasoline and diesel consumption is small but is increasing quickly. This short presentation aims to show BNEF's assessment of the fossil fuel displacement caused directly by EVs sold globally from 2011 to 2016.

UNITED NATIONS: Secretary-General Antonio Guterres warned that by 2050 global demand for fresh water is projected to grow by more than 40 per cent and at least a quarter of the world's population will live in countries with a "chronic or recurrent" lack of clean water.
By 2050, nearly two-thirds of humanity — more than 4 billion people — will live in cities. How should the world’s urban centers brace for impact — and ensure quality of life for the people who call them home?
Finland-based Vaisala last week released a paper that compares observational data from nearly 200 ground stations across six continents with satellite-derived irradiance records from five different versions of the company’s global solar dataset.
