Is climate change causing a rise in the number of mosquito and tick-borne diseases?

Is our changing climate making regions of the US more suitable for ticks and mosquitoes that spread diseases? Or is the climate changing human physiology making us more vulnerable?

World hunger has risen for three straight years, and climate change is a cause

After declining for nearly a decade, the number of hungry people in the world is growing again. Climate change, which is disrupting weather patterns that farmers rely on, is a major cause.

What is climate-ready infrastructure? Some cities are starting to adapt

Infrastructure systems – roads, water treatment systems, power grid – can't be built the same ways as in the past. What's a better roadmap for the future?

How a game can move people from climate apathy to action

In the 'World Climate' simulation, people play delegates to UN climate negotiations and work to strike an agreement that meets global climate goals. Playing it has made thousands want to take action.

Bioenergy carbon capture: climate snake oil or the 1.5-degree panacea?

Delays on climate action to reduce emissions means that we may have to consider technologies that strip carbon dioxide from the atmosphere. But that will come at a cost.

Why we can’t reverse climate change with ‘negative emissions’ technologies

The UN's panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
