CALL’s purpose is to learn together, support one another and advocate for solutions that make the world a safer, more affordable and healthier place to live.

Learning about climate change and biodiversity loss turns curiosity and concern into knowledge and action.  CALL’s mission is to unite individuals, nurture mutual support, and champion solutions that make our overheating planet safer, healthier and more affordable for our families, communities and future generations.

We believe collective learning, advocacy and a commitment to practical solutions can drive meaningful change.  We recognize the urgent need to transition from fossil fuels to clean, renewable energy and to accelerate climate action.   Delay is not an option – later is too late.
