Evidence continues to build that humans are contributing to a climate change issue that is nothing but bad news for the planet. Hopeful stories from seven countries, including India, Indonesia, and China, show that efforts to combat climate change might finally be working.

A overview of 2014's Fixes columns - connecting the dots between 60 or so ways that people are trying to change the world.

In Colombia, traditional cattle pastures have caused soil degradation, deforestation, and desertification. To reconcile this, several thousand acres of land in Latin America have been transformed into a silvo-pastoral system of grazing and raising cattle with agro-forestry. The Colombia-based Center for Research in Sustainable Systems of Agriculture seeks to reduce pasture land by 26 million acres while increasing cattle numbers by 2019.

New York City black tar roofs cause a number of environmental problems, including air pollution, heat absorption that raises energy consumption, and storm water runoff in the sewer system. Efforts to turn these old roofs into green spaces cool the buildings, enable the containment of more rainfall, reduce sewer discharge, generate energy, and absorb carbon emissions. New York City has a pilot program offering financial help for green roofs.

Soil in Bangladesh is becoming increasingly saline and infertile due to climate change. Bangladeshi farmers have begun using a saline-tolerant rice seed in order to produce an abundant crop despite salty soil.
