Global Climate Change – The Technology
Challenge

Abstract
Anthropogenic emissions of greenhouse gases, such as carbon dioxide, have led
to increasing atmospheric concentrations which are at least partly responsible for
the roughly 0.7oC global warming earth has experienced since the industrial
revolution. With industrial activity and population expected to increase for the
rest of the century, large increases in greenhouse gas emissions are projected,
with additional and potentially substantial subsequent global warming predicted.
The paper provides a brief overview of the factors driving CO2 emissions for the
world and for selected countries, an examination of key technologies that would
be required for an aggressive mitigation program, and a concise sector-by-sector
summary of mitigation options, along with R&D priorities.
1 Introduction
The Intergovernmental Panel on Climate Change [1] concluded in 2001 that
anthropogenic emissions of greenhouse gases, such as carbon dioxide (CO2),
have led to increasing atmospheric concentrations which are to be at least partly
responsible for the roughly 0.6oC global warming earth has experienced since the
industrial revolution. Since 2001, warming has now increased to an estimated
0.7oC (NCAR [2])
In Figure 1, IPCC [1] has summarized historical and projected trends for
atmospheric concentrations of CO2. In order to make these projections, the Panel
evaluated a range of scenarios, including alternative business-as-usual cases and
various mitigation scenarios. As Figure 1 shows, the projected concentrations
can be as high as 1000 ppm compared to a pre-industrial level of 280 ppm and a
