The issue focused on technology innovation and climate change. The scientific research literature clearly indicates that technological innovation has played a central role in reducing emissions of greenhouse gases. Technology innovation will continue to make progress towards climate mitigation. However, technologies should not be adopted without sufficient science to determine their environmental impacts. Scientific studies need to be scientifically rigorous and empirical. Scientists must study specific technologies as well as climate change science to assess the scientific uncertainty associated with climate change and technologies. Science research also needs to focus on engineering technologies that would reduce
