Global heating will make it much harder for tropical plants to germinate, study finds

Temperatures will be too hot for the seeds of one in five plants by the year 2070, Australian researcher says

Global heating will make it much harder for tropical plants around the world to germinate, with temperatures becoming too hot for the seeds of one in five plants by the year 2070, according to a new study.

Global heating will impact the ability of more than half of all tropical plants to germinate if emissions of greenhouse gases remain high.
