greening

Usually, at this time of year in Southern California, “the ground is wet, the grass is greening up, and you don’t have vegetation that is brittle,” said weather service meteorologist Alex Tardy.

Some studies suggest that this “greening of the Earth” could partially offset rising greenhouse gas emissions by storing more carbon in plants.

Citrus greening isn’t the first time Southern California citrus has faced an apocalypse.

You see tiny sprouts inching out of fallen trunks, head-high green shoots overshadowing charred remnants and towering old trees whose branches are greening again, despite jet-black charred bark below.

With house building a priority for the new UK Government, researchers at the University of Surrey are urging city planners not to forget to build "greening areas" such as parks in new communities.
