The scientists got the ball rolling with regard to climate change awareness, and their research continues to lay the groundwork for the world's understanding of climate change. Without the dedicated work of researchers, the world wouldn't know about the effects that our actions have on the planet.
People around the world, who value courage in telling the truth, despite extraordinary pressure and threats, applauded James Hansen, scientist and advocate for urgent solutions to climate change, for speaking up when the U.S. federal government tried to censor his work with NASA on climate change. This censorship is the subject of Mark Bowen's book Censoring Science: Inside the Political Attack on Dr. James Hansen and the Truth of Global Warming (Dutton).
Although Hansen works as a physicist on major climate change modeling, his work outside the office has had the greatest impact on the fight against global warming. He has made it a personal mission to communicate climate change to the public in the most clear-cut way possible.
Pachauri is the current chair of the IPCC, the volunteer-based group that shared the 2007 Nobel Peace Prize with Al Gore for work on climate change. The pressure has been on Pachauri since 2002 because his position as chair has never been more important.
Pachauri, along with many other leading IPCC scientists, attends all the UN Climate Change Conferences and delivers presentations explaining the latest science to negotiating bureaucrats. He also writes IPCC reports about the science of climate change for politicians and the public.
