Climate change is one of the biggest challenges we currently face, with an almost infinite complexity affecting all aspects of our lives. Explaining the science and importance of climate change is not easy. Targeted communication with maps and graphics makes it easier to grasp what it's all about. Many of us now have the power to work closely with data, but we also need to know how to use that data to reach policymakers and the public. Communicating effectively without getting lost in the complexity of the topic is also essential. In our role as environmental communications experts, we have joined forces to establish a training program to build capacity in using maps and graphics to explain climate change. The training is scheduled as a full-day workshop just before the international COP15 climate meeting. We invite you to attend the workshop, on December 4th 2009 in a central location in Copenhagen, Denmark. The workshop is designed for anyone involved in communicating climate change issues: scientists, journalists, communicators and many more.
