Communities around the world are feeling the impacts of climate change. The coming summer heat is a stark reminder that our planet is in peril, urging us to invest in mitigation to curb climate change’s relentless advance and adaptation to safeguard our communities against its inevitable impacts.

My recent conversations with communities across the globe from the Pan-African Peacemakers Alliance (PAPA) to the University of Alaska Fairbanks Climate Scholars program have underscored the haunting reality: climate change is already here and threatening peoples’ very ways of life. The US must do more at home and abroad to tackle it and help people adapt to impacts in ways that protect them and their identities.

South Sudan

Recent years have brought South Sudan both droughts and floods leading to hunger crises, displacement, and conflict. Climate change has increased tensions between smallholder farmers relying on rain-fed production and nomadic pastoralists because droughts make it harder for both groups to find enough land and water. In rural communities, flooding has caused the loss of homes, cattle, crops, and longstanding customs. Communities that have relied on farming to feed themselves are now under extraordinary strain, forcing many to move to cities that do not have the support capacity to receive them. Additionally, the impacts of floods and associated violence have hit the most vulnerable the hardest, especially women and children.

PAPA and its founder/director, Yoal Gatkuoth, do important work with communities in South Sudan to reduce tensions between different groups. The underlying problem? Climate change is worsening, and the country does not have the resources to adapt to it. They are not alone. While developing countries have done the least to cause climate change, they are experiencing its worst effects and often lack the financial resources to adapt.

Fairbanks, Alaska

Climate change is not just an international challenge. As the students from the University of Alaska, Fairbanks pointed out, Alaskan communities are facing flooding, coastal erosion, severe winter storms, and wildfires. The thawing of permafrost soil can damage pipelines, buildings, roads, and water supplies. Experts estimate the cost of maintaining public infrastructure may increase by 10-20% over the next 20 years.

As the hot summer months begin in earnest, it’s time to recognize the role the US must play in advancing effective climate solutions around the world.

Like in South Sudan, climate change is affecting the availability of food in Alaska and is decimating traditional cultures. The increasing acidity of the ocean is affecting the fishing industry, which is the state’s third largest economic driver and a vital food source for many in the state. Alaska Natives are particularly vulnerable, since loss of sea ice limits hunting grounds and reduces habitat for traditional food sources, impacting groups such as the Yup’ik, Iñupiat, and Inuit. For many of these Indigenous communities, the impacts of climate change aren’t simply about the reduction of economic wellbeing — it is about a loss of their culture and their very ways of life.

Climate Change Knows No Borders 

Leadership in international climate assistance is essential for addressing the urgent challenges posed by climate change. Helping developing countries reduce greenhouse gas emissions, protect critical ecosystems, and transition to renewable energy helps us reach global goals to mitigate climate change. Initiatives like USAID’s Adaptation Fund helps communities in developing countries build resilience and respond to the challenges posed by the climate crisis. It is also financially responsible, as every dollar spent on resilience saves $3 that would have been spent on humanitarian assistance. By proactively engaging in climate assistance efforts, the US can mitigate these risks and promote global stability.

Domestically, the US took decisive climate action through the Inflation Reduction Act, the largest investment to address climate change, support sustainable agriculture practices, and conserve natural resources. The federal government needs to do more to help communities already experiencing climate impacts, increase resiliency across the country, and create a more efficient disaster planning response. This would be a smart financial investment as, according to FEMA (Federal Emergency Management Agency), each dollar invested in resilience saves $6 when there is a disaster, not to mention the human cost and the financial costs for individuals.

As the hot summer months begin in earnest, it’s time to recognize the role the US must play in advancing effective climate solutions around the world. From Fairbanks to South Sudan and every community in between, more can be done to effectively steward this amazing world upon which we live. Investing in proactive measures and resilience-building strategies will secure a sustainable future for generations, ensuring global environmental justice that respects every community and culture on our planet.
