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.

One-third of boys in the developing world don’t face the risk of marriage and pregnancy before age 18. There are no laws preventing men from owning land or property. Men don’t bear the brunt of increasingly frequent and severe disasters. And men don’t hold fewer than 25 percent of parliamentary seats worldwide.

Mass displacement has become a significant feature of recent conflicts, as the number of people forced to flee their homes has passed 50 million worldwide, a level not seen since World War II. This is one of the reasons why the UN Security Council will focus on women refugees and internally displaced persons (IDPs) during its annual open debate on women, peace, and security on October 28, according to Elizabeth Cafferty, senior advocacy officer at the Women’s Refugee Commission.

In August, armed men stormed an Ebola clinic in Monrovia, Liberia, releasing infected patients and stealing contaminated bedding. The following month, eight health workers were attacked and killed in a Guinean village as they tried to educate residents about the deadly disease; their bodies were found in a village latrine. Days later, Red Cross workers in western Guinea were assaulted as they tried to collect and bury Ebola victims.

Motivated in part by mounting public pressure to cut down on the smog created by more than 600 coal-fired power plants, China’s nuclear energy capacity is growing faster than any other country in the world.

Much of the time, discussion about climate change is focused on the future – How bad will it be? Will it lead to more conflict? Who will be most vulnerable? But it is in fact a current phenomenon. The climate system is already, for all intents and purposes, irrevocably changed and millions of lives have been changed along with it.
