Blue Nile state has experienced significant impacts from climate change, being one of Sudan's fastest-warming regions. Since the 1970s, temperatures have risen by 1 °C (1.8 °F) each year. Moreover, there has been a 30 years decline in rainfall, which is becoming more irregular. Groundwater depletion has been observed Wad el-Mahi. Seasonal floods from the Blue Nile river and other streams have also worsened environmental conditions. Environmental degradation has been exacerbated by the excessive cutting of trees for charcoal production and improper handling of liquid and solid waste.[8]

Medium-range estimates of Arctic carbon emissions could result from moderate climate emission mitigation policies that keep global warming below 3°C (e.g., RCP4.5). This global warming level most closely matches country emissions reduction pledges made for the Paris Climate Agreement...

"The IPCC doesn't make projections about which of these scenarios is more likely, but other researchers and modellers can. The Australian Academy of Science, for instance, released a report last year stating that our current emissions trajectory had us headed for a 3°C warmer world, roughly in line with the middle scenario. Climate Action Tracker predicts 2.5 to 2.9°C of warming based on current policies and action, with pledges and government agreements taking this to 2.1°C.
