A study led by a UC Riverside atmospheric scientist predicts that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be caused by complex changes in the atmosphere spurred by carbon emissions that influence...

If aliens modified a planet in their solar system to make it warmer, we’d be able to tell. A new UC Riverside study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet. A terraformed planet has been artificially made hospitable for life. The gases described in the study would be detectable...
