Scientists were frustrated by a piece in the Guardian earlier this week that seemed to call into question the science on microplastics in the body.
I wrote about why researchers are certain microplastics are in the human body -- and what we still don't know:

A scientist questioned new microplastics findings. Then other researchers fired back.
A prominent scientist criticized microplastics research methods. Others are defending the work.

A new study by GEOMAR and Plymouth Marine Laboratory shows that the exchange of gases between air and sea is not symmetric, and that the global ocean has taken up around 15 per cent more CO2 than suggested by conventional estimates.
