Climate change negotiations seem to crawl along interminably at the pace of the glaciers they are meant to protect, with little perceptible progress as meeting follows meeting and conference follows lackluster conference. But this year we are seeing remarkable momentum building toward a historic conference in Paris in the closing days of 2015, by the end of which we will either have a new international agreement on cutting greenhouse gas emissions, or we will have seen the last of truly global efforts to strike a deal on saving our planet.

You could say the people living along the banks of the Thondwe River in southern Malawi were lucky. At least they’d been warned of the flash flood in early January that would burst through an earthen dike, wash away their homes and crops, and leave more than 4,000 of them homeless.

Rice is a thirsty crop. Yet for the past three years, Alberto Mejia has been trying to reduce the amount of water he uses for irrigation on his 1,100-acre farm near Ibague in the tropical, central range of the Colombian Andes.

It is no longer news that Nigeria is a peculiar country, a nation with huge human and natural resources, and whose diversity of peoples and internal geographies is a blessing.

The potential security challenges linked with climate change can make for great headlines. While sensationalist claims about water wars, states collapsing in chaos, or the forced migration of hundreds of millions cannot be completely discounted for the long term, intelligent mitigation and adaptation efforts can help avoid the worst of these – and manage the rest.

Imagine an overgrown perennial garden. Impenetrable, shrubby bushes knit themselves together in long rows. Grasses reach chest high. Native hardwood trees hog the perimeter.

New York City Mayor Bill de Blasio has called for “urgent, daring action” to help deliver on his pledge to reduce New York City’s greenhouse gas emissions by 80 percent by 2050. The Mayor asked us all to think about “the reckless way in which we live.”
