A week or so ago we published a list of the Top 50 Women in Climate to Follow on Twitter. This sparked an amazing reaction, as well as a deluge of follow up emails and tweets highlighting yet more amazing women leading the charge on climate science and policy especially.

Building on suggestions from this feedback, and just in time for COP23, we have compiled a list of ladies leading the way in discussions on all things climate and sustainability. This time we have grouped these leading ladies into their sectors of science, policy, writers/journalists, NGOs, and private sector.

They are once again listed in order of the number of followers on Twitter, pick your faves or do yourself a favour and follow them all.
