The inevitability of changes
occurring to the climate at both global and local scales is now a
well-established reality. Confidence is currently higher than in previous
assessments with regard to projected patterns of warming and other features of
a regional scale, including changes in wind patterns, precipitation and some
aspects of extremes and sea ice. For poor countries in Africa, Asia and Latin
America, climate change adds another layer of complexity to already existing
development challenges, such as high levels of poverty and inequality, rapid
population growth, underdeveloped financial markets and weak governance
systems.
Climate research at the Earth
Institute spans multiple disciplines. While climate scientists study the
effects of increased temperatures and atmospheric carbon dioxide on the world’s
oceans and weather patterns, engineers are seeking ways to produce cleaner
energy and provide steady supplies of fresh water. Social scientists, policy
experts and lawyers are studying human behaviour in the face of change as a way
to improve how we make decisions, and the policy and legal tools we can use to
implement measures that address the climate challenge. The Columbia Climate
centre integrates research from throughout the University and across
disciplines to translate the best climate knowledge into practical solutions
In humankind’s pursuit of
well-being, we both influence and respond to climate. Anthropogenic emissions
of greenhouse gases affect the heat balance of the Earth, and the resulting
changes in precipitation patterns, temperature extremes and rising sea levels
affect how society develops. The dynamic interaction between humans and climate
is not new, but the scale of the interaction has reached unprecedented
proportions.
