Uneven heating of the Earth’s surface—what it means. Regional variations of climate change is a subject that is gaining much attention, with new findings that provide unexpected worries and requirements for mitigation. For example, “The global budget to keep within 2 degrees mean warming level is cumulative emissions of about 850 gigatonnes (GT) of carbon, the paper said. To prevent the Mediterranean region warming by that amount, however, the budget is about 600GT.” In such places the future is almost or already here.
