Flowers in a meadow The next state of equilibrium during which humans will live in balance with the Earth’s ecosystems depends on the choices we make today. In turn, those choices are influenced by the way we view Earth. Daily, we each make decisions that impact our environment; collectively our actions affect the health and well being of Earth. Individually and collectively, we have the power to influence our environment and therein resides our hope for future generations.

Small Image of scientists attempting to launch a weather balloonIt has become clear in recent years that human beings need to be much more careful in how we develop the Earth’s resources if that development is to be sustainable for future generations. To support sustainable development, in turn, we need to know the present state of the Earth and the impact of our activities. Measuring that impact and sharing the results with decision makers around the world is the goal of a major international scientific effort, the Global Earth Observation System of Systems (GEOSS).

Mahlman chaired the Earth System Science and Applications Advisory Committee for NASA’s Mission to Planet Earth program in the 1990s and was involved in the founding of the IPCC; He created the so-called betting odds scheme used by IPCC to evaluate uncertainty and was a reviewer of the Working Group I report for IPCC’s 2007 assessment.
