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.

The report, produced by the U.N. Office for Disaster Risk Reduction, estimates that an investment of $6 billion annually in measures to reduce the risk of disasters would save the world from losses of $360 billion over the next 15 years. ...

“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. ...

Ocean acidification may cause dramatic changes to phytoplankton

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. ...

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.

He told the Security Council that "strains on water access are already rising in all regions," noting that three- quarters of the 193 UN member states share rivers or lake basins with their neighbors.

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.

The company said that the results of the study indicate that Vaisala's values for global horizontal irradiance (GHI) — the key variable for PV projects — have a standard deviation of bias error, or uncertainty, of 4.4-4.9 percent, depending on the version of the dataset. ...
