Atlantic Ocean circulation at weakest in a millennium, say scientists

Fiona Harvey  – Environment correspondent – the Guardian – Fri 26 Feb 2021

 

Further weakening of the Atlantic Meridional Overturning Circulation (AMOC) could result in more storms battering the UK, more intense winters and an increase in damaging heatwaves and droughts across Europe. A weakened Gulf Stream would also raise sea levels on the Atlantic coast of the US. Read more here.

Atmospheric CO2 now hitting 50% higher than pre-industrial levels

the Carbon Brief – GUEST POSTS , 16 March 2021  

…Records derived from ice core measurements show that the average global CO2 concentration in the atmosphere for 1750 to 1800 was around 278ppm. This is the value that the Intergovernmental Panel on Climate Change (IPCC) used as the pre-industrial baseline for CO2 in its fifth assessment report (pdf), published in 2013-14. 

Atmospheric CO2 has been rising ever since – driving ongoing warming of the global climate. Now, in March 2021, levels have reached around 417ppm – a 50% increase over the 1750-1800 average.
