The threshold for dangerous global warming will likely be crossed between 2027 and 2042 – a much narrower window than the Intergovernmental Panel on Climate Change’s estimate of between now and 2052. Scientists have been making projections of future global warming using climate models for decades. These models play an important role in understanding the Earth’s climate and how it will likely change. In analyzing the results, the researchers found that the threshold for dangerous warming (+1.5oC) will likely be crossed between 2027 and 2042. They also found, however, that the “very likely warming ranges” of the SCRF were within those of the GCMs, giving the latter support.
