Today the World Meteorological Office (WMO) based in Geneva, Switzerland, issued a document named The State of the Global Climate in 2019. It contains the draft figures that making the last year the second warmest year of all time on record.

The document starts with a disappointing, perhaps even frightening, statement that had been presented by Antonio Guterres, the United Nations Secretary-General “we are currently way off track to meeting either the 1.5 degrees Celsius (2.7F) or 2C (3.6F) targets that the Paris Agreement calls for.”

Ocean warming delivers widespread impacts on the climate system and contributes more than 30 per cent of sea-level rise simply through thermal expansion of seawater.

Together with ocean acidification and deoxygenation, ocean warming can lead to dramatic changes in marine ecosystems, the experts say.

Sea level has risen throughout the satellite altimeter record (since 1993), but the rate has increased over that time, mainly due to the melting of ice sheets on Greenland and Antarctica. In 2019, the global mean sea level reached its highest value on the record.
