A recent increase in the abundance of particles high in the atmosphere has offset about a third of the current climate warming influence of carbon dioxide (CO2) change during the past decade, according to a new study led by NOAA and published today in the online edition of Science

In the stratosphere, miles above Earth’s surface, small, airborne particles reflect sunlight back into space, which leads to a cooling influence at the ground. These particles are also called “aerosols," and the new paper explores their recent climate effects -- the reasons behind their increase remain the subject of ongoing research.

Story

(Based on the article entitled “A general source-sink model with inoperability constraints for robust energy sector planning.” Applied Energy vol. 88: pp. 759-3,764.)

The role played by low-carbon energy sources in the global struggle to mitigate anthropogenic climate change is already well understood. The International Energy Agency envisions the integrated adoption of multiple “technology wedges” consisting of renewables, energy efficiency, carbon dioxide capture and storage (CCS) and even nuclear energy in order to reduce the total global release of greenhouse gases to manageable levels.

Story

Abilio da Fonseca is a driven man. The PhD candidate and Timor-Leste citizen wants one thing above anything else, and that is to contribute to helping the island nation and its one million- plus population to prosper. But prosperity will never come unless the world’s youngest democracy can repel the newest threat to its shores.

Raised in a fishing village where lives depend on the resources of the sea, Abilio is a young man fighting a new peril that is snapping at his nation – climate change.
