Global Climate Change Center

Global climate change is a matter of intense concern and public importance. There can be little doubt that human beings influence the world's climate. At the same time, our knowledge of the extent, progress, mechanisms and results of global climate change is still incomplete. New data are becoming available every day - from tree rings to deep sea samples, ice cores, glacial changes and climatological models - while the greatest minds all over the world are working to better understand climate change and its impact on life on earth.

What is weather?

TV weather reporters need all the information they can get in order to predict the weather for just a few days.

Weather is local and temporary.

On our own Earth, we cannot control weather by turning a thermostat up to make it warmer or down to make it cooler. The best we can do is try to predict the weather. Weather scientists, called meteorologists, try to foresee what's going to happen next.

Climate change mitigation

Fossil fuel related CO2 emissions compared to five of IPCC's emissions scenarios. The dips are related to global recessions.

Attribution of recent climate change

This graph is known as the Keeling Curve and shows the long-term increase of atmospheric carbon dioxide (CO2) concentrations from 1958–2015. Monthly CO2 measurements display seasonal oscillations in an upward trend. Each year's maximum occurs during the Northern Hemisphere's late spring, and declines during its growing season as plants remove some atmospheric CO2.

Why Does the Church Care About Global Climate Change

At its core, global climate change is not about economic theory or political platforms, nor about partisan advantage or interest group pressures. It is about the future of God's creation and the one human family. It is about protecting both 'the human environment' and the natural environment. (Global Climate Change: A Plea for Dialogue, Prudence and the Common Good, US Catholic Bishops, 2001)
