A special report on limiting global warming released on Monday by a UN scientific panel, should be heard around the world as an "ear-splitting wake-up call" said UN chief António Guterres. He said the long-awaited findings show that "climate change is running faster than we are - and we are running out of time."
The IPCC, or Intergovernmental Panel on Climate Change (IPCC), issued the report from Incheon, Republic of Korea, where for the past week, hundreds of scientists and government representatives have been poring over thousands of inputs to paint a picture of what could happen to the planet and its population with global warming of 1.5°C (or 2.7 degrees Fahrenheit).
Limiting global warming will require “far-reaching and unprecedented changes” to human behaviour, according to the panel. "We are already seeing the consequences of 1°C of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes,” said Panmao Zhai, Co-Chair of one of the IPCC Working Groups.
The landmark Paris Agreement adopted in December 2015 by 195 nations at the 21st Conference of the Parties to the UN Framework Convention on Climate Change (UNFCCC), included the aim of strengthening the global response to the threat of climate change by “holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels.”
"it is not impossible to limit global warming to 1.5°C, according to the report. "But it will require unprecedented and collective climate action in all areas. There is no time to waste."

- Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate
- Climate-related risks for natural and human systems are higher for global warming of 1.5°C than at present, but lower than at 2°C
- Climate-related risks to health, livelihoods, food security, water supply, human security, and economic growth are projected to increase with global warming of 1.5°C and increase further with 2°C
