Climate change has become part of our daily lexicon. Rarely does a week pass when a hurricane, drought, wildfire, or some other climate disruption is not front page news. These headlines often offer dire predictions of mass migration as well—a bracing vision of hordes of people moving to greener pastures, often found further inland and further north, where some political leaders leverage the narrative to push their own agendas.

The Population Institute’s recent report, Invisible Threads: Addressing the root causes of migration from Guatemala by investing in women and girls, has brought attention to the numerous factors that drive migration in Guatemala. One of the key factors addressed in the report is climate change, which is linked closely to issues concerning land in that country. To this day, multiple generations of indigenous women endure the effects of land displacement and inequities in access to land—as well as related social and economic pressures. In concert with other political, social, and economic problems, this particular challenge has resulted in large outflows of migrants from the region.

Just in the last minute, 169 more people were born on planet Earth, and everyday more than a quarter of a million are added to that total. John Milewski, Moderator of Wilson Center NOW, laid out these astonishing facts at the beginning of a Wilson Center NOW conversation on the implications of global population growth with Wilson Center Fellow Jennifer Sciubba on November 14— the eve of the historic day when the number of people on the planet officially surpassed 8 billion. 

As the world’s attention has turned in November 2022 to the UN COP 27 climate change conference, another important global milestone is also drawing attention. Today, November 15, 2022, the global population is predicted to reach 8 billion. By 2050, it will be 9.7 billion.

Often cast into the backwaters of U.S. foreign policy, sub-Saharan Africa now looms large as the Biden Administration grapples with a wide range of global challenges. President Biden will soon host the upcoming Africa Leaders’ Summit in Washington, that acknowledges the U.S. government must do much more in Africa in order to advance U.S. interests and global prosperity.

In recent years, a growing proportion of migrants at the US southern border have come from Guatemala, El Salvador, and Honduras. This surge of migrants from Central America has prompted the U.S. government to seek to better understand and address the root causes of migration from the region. One substantive response came in July 2021, under Executive Order 14010, when the Biden-Harris Administration released what has become known as the Root Causes Strategy. The White House pledged to commit $4 billion over four years on efforts to address drivers of irregular migration from these three countries.

On November 15, the world population is projected to reach 8 billion people. As we approach that milestone, there’s no denying that our rapidly growing human population also places extraordinary pressure on the environment. The human population has doubled in the last 50 years, while wildlife populations have been cut in half.
