UN warns of record-breaking global temperatures and irreversible climate change.

The World Meteorological Organization has warned that the planet is on track to have its hottest year ever for at least one of the next five years, and that the planet will likely surpass a major climate change threshold. There is a 66% chance that global temperatures will exceed 1.5 degrees Celsius during the coming five years, and a 98% likelihood that at least one of the next five years will be the warmest on record. The Arctic is expected to see temperatures three times the global average, which will have significant impacts on ecosystems. The UN has warned that at this level of global warming, precipitation and droughts will both be more frequent and intense, and there will be far greater risks related to energy, food and water.
