In a Snapshot, “Sea” the Future Today

Cuong Tran and Diana Lopera, , UCS

They say that a picture can speak a thousand words … but what if the picture could paint a future 10, 50, 100 years from now? And not just a future that’ll impact one person, but rather the future that will impact many.

East African Locust Crisis Shows how Climate Change Threatens Food Security

, Policy Director and Lead Economist, Climate & Energy

Huge swarms of desert locusts are advancing across the Horn of Africa, threatening crops that millions of people depend on for food. UN Food and Agricultural Organisation (FAO) Director-General Qu Dongyu has called this “a situation of international dimensions that threatens the food security of the entire subregion.” The unprecedented scale of this infestation has been fueled by climate change, which has contributed to ocean conditions favorable for the unusually high number of cyclones (8 in 2019) and extreme rainfall in the region, creating ideal breeding conditions for locusts.

Bushfire-Ravaged Australia Is Crying for Climate Action

, climate scientist

I’m writing from Australia with a heavy heart and a growing sense of anger.

Uncontrolled bushfires, sparked in September and raging since October, continue to ravage the southern and eastern parts of the continent. So far, 25 people have lost their lives, thousands of houses have been destroyed, and whole towns have been razed to the ground. Countless native animals and livestock have died. Communities are grieving.  And there are months left to go in this fire season.

While the unfolding tragedy that has captured global headlines highlights our vulnerability in a rapidly warming climate, it also exposes a gaping absence of climate leadership both in this country and globally. Communities have been left shattered, exhausted and looking for answers. As a climate scientist who has been working on these issues for decades, I share below some thoughts on how we got here and the urgent new course we need to set. Read more >

, Climate Resilience Analyst

This morning, Pentagon officials will testify during a Senate Armed Services Committee  hearing on “Strategic Threats, Ongoing Challenges, and National Defense Strategy Implementation.” It has been reported that the hearing will likely focus on how the current Pentagon officials are Implementing the National Defense Strategy, a policy document that is a clear departure from previous administrations in many ways, not least in its omission of climate change as a national security threat.
