Developing Countries to Become Major Climate Change Contributors by 2030—Later Than Previous Estimates

Developed nations have dominated global surface temperature change historically, and according to a new study, they will continue to do so until 2030, when developing nations, particularly the two population giants—China and India—will overtake them. 

“This is significant,” said lead author Daniel Ward, a postdoctoral researcher from Cornell University, because most human-induced “climate change will come from developed countries until about the year 2030, whereas previous estimates put this ‘crossover’ year at 2020 or earlier.”

Only a Fraction of Cauliflower Coral Larvae May Tolerate Ocean Conditions in 2100

Coral reefs are undoubtedly the treasures of our oceans. Every month during the new moon, cauliflower corals found thriving in the shallow waters of the Indian and Pacific oceans, release larvae that migrate through currents and swim to faraway locations for settlement. Swimming requires large amounts of energy reflected in high metabolic rates among larvae. But few survive this journey fraught with danger; they are at risk of predation and vulnerable to dynamic ocean environments. Adding to their woes, climate change may render our oceans warmer and more acidic by the of the century. How will cauliflower coral larvae respond to these environmental changes? A study suggests that only a fraction may possess the ability to adapt and persist.
