Population and Climate Change by Brian C. O'Neill download in ePub, pdf, iPad

Fragile states are either already embroiled in violent conflicts, whether internal or cross-border, or are at high risk of so being in the future. Smaller families are more resilient. Almost all medium-term climate change, like almost all medium-term population change, is already baked in the cake. The average miles traveled per capita is increasing rapidly, and the transportation sector now accounts for one-third of all U. The time factor is crucial.

Smaller families are more resilient

More Americans are driving farther to reach bigger homes with higher heating and cooling demands and fewer people per household than ever before. Future growth amplifies the consequences of people's reproductive choices today, the same way that compound interest amplifies a bank balance. But reducing fertility can only affect total population in the long term.

But thinking about population pulls us in the direction of adaptation. Time is short, but it not too late to stop runaway global warming.

Fragile states are either already embroiled

As temperatures heat up, seas begin to rise which ultimately threaten low-lying areas, coastal populations, and ecosystems. Landis MacKellar is an economist and lawyer whose published research has spanned demography, the economics of the social sector, and natural resource and environmental economics.

Large cities are, for historical reasons having to do with transport, usually located on the coast or in floodplains adjacent to major waterways. But while population growth is stagnant or dropping in most developed countries except for the U. All of these trends exacerbate the carbon footprint inherent in the basic energy needs of a burgeoning U.

Their enormous positive effect is a result of their proven effectiveness in reducing family size and population growth. For video of the full conference, visit our YouTube channel. But in the poorest and most vulnerable countries, insurance is either non-existent or too expensive and governments know that if the worst happens, humanitarian outrage will force donors to step in.

These two huge environmental problems are inseparable and to discuss one while ignoring the other is irrational. It points to three areas where interventions will strengthen resilience starting right now, climate change or no climate change. In fact, their research established that it was times more effective than the next most effective measure, living without a car. Moreover, demography underpins a strong ethical argument to support adaptation even at the expense of mitigation. Both climate change mitigation and adaptation are needed.
