© Crown copyright Met Office Why do I discuss climate science online? Try to better inform a controversial debate… Be visible as a climate scientist discussing science For many people, the only impression they have of discussions between climate scientists is the Climategate s Find out what other people think about the science and its implications, and why Includes both sceptics and activists Try to address misunderstandings / misrepresentations before they propagate further Again, includes both sceptics and activists

© Crown copyright Met Office Who are the contributors to climate sceptic blogs? Very wide range of understanding and opinions: Some appear to be incurably cynical* of the entire concept of man-made global warming Some accept that warming is happening and there is a human contribution, but are unconvinced that it is a significant problem Some have little in-depth knowledge of the science Some are well-informed, & read (& occasionally find errors in!) scientific papers. Some are scientists themselves * The label “denier” tends to offend & close off discussion

© Crown copyright Met Office What are the attitudes towards climate scientists on sceptic blogs? Undercurrent of mistrust towards climate scientists, eg: Perceptions / accusations of malpractice / incompetence, esp. through Climategate / Hockey stick affairs Perceived political motivations – climate science seen as closely tied to Green or left-wing politics, or as part of government control & taxation Seen as scaremongering in order to gain funding Feelings of marginalisation – excluded from discussion Welcome discussion with scientists (sceptics often stonewalled) Often have genuine questions about the science and like to hear the answers Arrogant, impatient attitudes tend to send the discussion of the rails A civil attitude generally promotes a response in kind

© Crown copyright Met Office Can a productive conversation be had? Yes! Don’t underestimate audience Stay calm, polite and respectful even when responding to criticism, and especially when correcting inaccuracies / misconceptions Exert your right to insist that others do likewise! Be open about scientific uncertainties – don’t worry about things being “misused”. This is science, not law. Remember a potentially large audience of “lurkers” (people who read without responding). Often this is the main audience you are reaching, not the people who are replying to you.

© Crown copyright Met Office Is there room for doubt? Scientists are here to find the truth. Our job is to ask questions Level of certainty varies widely for different aspects of climate science Uncertainty cuts both ways in informing decisions Over-simplified messaging in “Climate communication” sometimes seen as brushing uncertainties under the carpet, and can close down scientific discussion “Doubt is not to be feared, but welcomed and discussed” – Richard Feynmann

© Crown copyright Met Office Not communicating climate change but communicating climate science I do not aim to convince people to take action to mitigate climate change Plenty of others trying to do that already Instead, my aim is to help people understand & trust the science so they can make their own decisions Reputation of climate science is tarnished. Need to rebuild trust Climate science is an active, evolving science, with big questions still to be answered Pretending we have all the answers is seen through and simply maintains the loss of trust Sitting round agreeing with each other is boring
