Climate change is not only about melting ice caps and polar bears. Climate change is about people.

Guest blog post (for Blog Action Day: Climate Change) from CARE International's, Simon Owens:
Swinging weather patterns are creating disasters on a scale that human civilization has never before witnessed. For the world’s poorest people – the ones least equipped to deal with its effects – climate change is devastating their crops, livelihoods and communities.

"Climate change is worsening the plight of those hundreds of millions of men, women and children who already live in extreme poverty – and it threatens to push hundreds of millions more people into similar destitution," says CARE International’s Secretary General Robert Glasser. "A concerted international response to this unprecedented challenge is required if we are to avoid catastrophic human suffering."

CARE is working toward a world where poor people can create opportunity out of crises like climate change. But the current reality is that climate change makes poor people even more vulnerable.

For instance, agricultural production will likely decline in the poorest countries, especially in sub-Saharan Africa. Less reliable rainfall will likely affect planting seasons, crop growth and livestock health – and lead to increased malnutrition. In other parts of the developing world, flooding will likely further diminish the quality of already-marginal soil and could cause outbreaks of water-borne diseases such as cholera and dysentery.

Climate change also is hurling many poor families into "Catch-22" situations. For example, they may select crops that are less sensitive to rainfall variation, but also less profitable. As incomes decline and people are not able to eke out a living, children are forced to leave school, assets are sold off to afford essentials, malnutrition rates increase and large-scale migration ensues. The end result? Deepening poverty for tens of millions of people around the world.

What Must Be Done?

At the international level, negotiations to develop a new treaty to guide global efforts to address climate change will take place in Copenhagen, Denmark in just a couple weeks. The United States must help lead those efforts, and forge a strong agreement that caps emissions, stops global warming and responds to the effects already in motion. We must do this for the sake of all of humanity.

What can I do to help?

First, you can make a tax-deductible donation to CARE to help poor families access the tools and education they need to adapt to the effects of climate change, make efficient use of their existing resources and overcome poverty for good.

Second, if you live in the Unites States, you can write your senators and urge them to pass the American Clean Energy and Security Act of 2009, a critical step toward U.S. leadership in tackling climate change. U.S. leadership is critical to making the Copenhagen negotiations a success.

Third, you can join the CARE mailing list to be kept up to date on CARE’s activities and other ways you can take action in the days counting down to Copenhagen.
