A new study in Nature [Ed-Abstract only for non-subscribers, but see below.] predicts that climate warming will be 15% greater than previous high estimates have predicted. This new study suggests that humans need to reduce greenhouse gas emissions more than previously expected and more than the Paris Agreement calls for. This study was based on analyzing the earth's "energy budget" (absorption and re-emission of radiation) and inputting that into a number of different climate models.
Also covered in more detail in Phys.org and in the Guardian.
The researchers focused on comparing model projections and observations of the spatial and seasonal patterns of how energy flows from Earth to space. Interestingly, the models that best simulate the recent past of these energy exchanges between the planet and its surroundings tend to project greater-than-average warming in the future.
"Our results suggest that it doesn't make sense to dismiss the most-severe global warming projections based on the fact that climate models are imperfect in their simulation of the current climate," Brown said. "On the contrary, if anything, we are showing that model shortcomings can be used to dismiss the least-severe projections."

But we are in an Ice Age right now... More specifically we are in the inter-glacial period of an Ice Age, which is likely to last few million years. Though there could be circumstances which cause the Ice Age to break prematurely. But if that does not happen, we are likely to suffer another glacial period like the one during what was historically referred to as "Ice Age", though it was largely incorrect use of the term but "Glacial Period" is less catchy.
Current Ice Age is actually quite remarkable due to 3 contributors: a large isolated land mass in the Southern Polar Region, an isolated body of water in Northern Polar Region, and the formation of the Himalayan Plateau which caused increased atmospheric precipitation (which causes reduction in atmospheric Carbon Dioxide).
