Scientist warning over climate change and global warming - CBBC Newsround

A new United Nations report has warned that unprecedented changes across all aspects of society are needed in order to limit unsafe global warming.

The 48th IPCC session in South Korea's western port city of Incheon brought together about 570 representatives from 135 countries and global organisations, Xinhua news agency reported.

President Donald Trump acknowledged receiving an alarming report on climate change from the United Nations' Intergovernmental Panel on Climate Change Tuesday, at the same time saying "I want to look at who drew it".

"One of the key messages that comes out very strongly from this report is that 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", Co-Chair of one of the IPCC Working Groups Panmao Zhai said.

At the Paris Climate Agreement in 2015, worldwide leaders agreed to keep global warming "well below 2°C above pre-industrial levels" with the hopes to limit this to just 1.5°C.

A stark new report from the global scientific authority on climate change calls on individuals, as well as governments, to take action to avoid disastrous levels of global warming.

Monday's report is three years in the making and is a direct result of the 2015 Paris Climate Agreement.

UN Warns the World has just over a Decade till 2030 to get Climate Change Under Control, reports Novinite.

"E$3 ven with erroneous attribution of extreme weather/climate events and projections using climate models that are running too hot and not fit for objective of projecting 21st century climate change, the IPCC still has not made a strong case for this massive investment to prevent 1.5C warming", she said on her Climate Etc. blog. Essential for pollinating crops, they will be more likely to lose half their habitat at two degrees than 1.5.

If 1.5 degrees of warming does occur, Southeast Asian countries like Indonesia, the Philippines, and Vietnam, including countries like Japan, China, Egypt, and the USA will experience increased flooding by 2040. "What we've done is said what the world needs to do", Imperial College London's Jim Skea, cochair of the IPCC panel, said at a press conference.

There were also 133 contributing authors.

"Though it will be very hard in the current global economic system to limit warming to 1.5°C, but it is not impossible".

Allowing the global temperature to temporarily exceed or "overshoot" 1.5ºC would mean a greater reliance on techniques that remove Carbon dioxide from the air to return global temperature to below 1.5°C by 2100.

"We show it can be done within laws of physics and chemistry".

The report says the rate of warming caused by human activities is speeding up and that global emissions would need to fall by 45% by 2030 - twice as fast as previously envisaged.

The Government and its climate advisers have been waiting for the findings of the report.

President Trump announced in June he would pull out of the Paris accord, saying it would put the US economy at a global disadvantage.

The latest research by the world's leading body on climate change highlighted that the promises countries have made so far to cut their emissions would put the world on track for 3C of warming by the end of the century.
