Plants are the original carbon capture and storage solution: as atmospheric carbon dioxide levels rise, plants absorb more of the gas to fuel photosynthesis, and more carbon is stored in the soil.

«Human influence is so dominant now,» Baker asserts, «that whatever is going to go on in the tropics has much less to do with sea surface temperatures and the earth's orbital parameters and much more to do with deforestation, increasing atmospheric carbon dioxide and global warming.»

Earth's average temperature has remained more or less steady since 2001, despite rising levels of atmospheric carbon dioxide and other greenhouse gases — a trend that has perplexed most climate scientists.

As emissions from human activities increase atmospheric carbon dioxide, they, in turn, are modifying the chemical structure of global waters, making them more acidic.

As atmospheric CO2 levels increase from burning fossil fuels, this carbon dioxide is soaked up by seawater and makes the oceans more acidic.

New research by University of Delaware oceanographer Wei - Jun Cai and colleagues at Université Libre de Bruxelles, Texas A&M University - Corpus Christi, University of Hawaii at Manoa and ETH Zurich, now reveals that the water over the continental shelves is shouldering a larger portion of the load, taking up more and more of this atmospheric carbon dioxide.

By analyzing global water vapor and temperature satellite data for the lower atmosphere, Texas A&M University atmospheric scientist Andrew Dessler and his colleagues found that warming driven by carbon dioxide and other gases allowed the air to hold more moisture, increasing the amount of water vapor in the atmosphere.
