According to this article on Science Daily, a new study suggests that hotter nights may wield more influence than previously thought over the planet's atmosphere as global temperatures rise.
They say this could eventually lead to more carbon flooding the atmosphere. During the past 50 years, the land-based carbon sink's "interannual variability" has grown by 50 to 100 percent! William Anderegg says that "Nighttime temperatures have been increasing faster than daytime temperatures and will continue to rise faster. This suggests that tropical ecosystems might be more vulnerable to climate change than previously thought, risking crossing the threshold from a carbon sink to a carbon source. But there's certainly potential for plants to acclimate their respiration rates and that's an area that needs future study."
This usually occurs in the tropics and can be seen with data from places such as Manaus, Brazil. (see image)
