Many of the green places and open spaces that need protecting most today are in our own neighborhoods. In too many places, the beauty of local vistas has been degraded by decades of ill-planned and ill-coordinated development.

The crisis is a concrete threatening reality today. It stands to get catastrophically worse unless we take action before the accumulation [of] this global warming pollution reaches such toxic levels that the problem becomes bigger than we can solve.

We're putting 70 million tonnes of pollution into the atmosphere every day, trapping an enormous amount of extra heat from the sun inside the earth's atmosphere. It's threatening to push the planet past a tipping point beyond which climate change would be difficult to stop

We are close to a time when all of humankind will envision a global agenda that encompasses a kind of Global Marshall Plan to address the causes of poverty and suffering and environmental destruction all over the earth.

At some point, a false belief collides with physical reality.

There are many who would much prefer that the word 'climate' never be mentioned and that the issue be eliminated from our national conversation.

Although I have a variety of obligations, the climate crisis is my central concern.
