Trump questions United Nations global warming report

Trump questions United Nations global warming report

The report was prepared in response to an invitation from the United Nations Framework Convention on Climate Change (UNFCCC) when it adopted the Paris Agreement in 2015.

The report issued by the Intergovernmental Panel on Climate Change says global warming is likely to reach 1.5 degrees Celsius above pre-industrial levels as early as 2030.

"This is one of the most important reports ever produced by the IPCC, and certainly one of the most needed", Hoesung Lee, the chair of the body, said at a press conference in South Korea on Monday.

The UN'S top panel IPCC has spent thousands of inputs for the past few weeks to paint a scenario of what could happen to the plants and inhabitants with global warming of 1.5ºC.

Countries in the southern hemisphere will be among the worse off, the report said, "projected to experience the largest impacts on economic growth due to climate change should global warming increase".

If the average global temperature temporarily exceeded 1.5C, additional carbon removal techniques would be required to return warming to below 1.5C by 2100. Even less than a degree increase in the global temperature would risk destroying the coral reefs, the Antarctic ice sheets and crops, as well as make the ocean more acidic.

"This report gives policymakers and practitioners the information they need to make decisions that tackle climate change while considering local context and people's needs".

Carbon emissions need to reach "net zero" by 2050 and almost halve from 2010 levels by 2030. Global CO2 emissions may need to peak around 2020.

It was Trump's first reaction to the report, which says that the Earth surface has warmed one degree Celsius (1.8 degrees Fahrenheit) and is on track towards an unliveable 3 degrees Celsius or 4 degrees Celsius rise. "But it will require unprecedented and collective climate action in all areas".

WA's Ningaloo Reef could be wiped out within three decades unless fossil fuels are phased out and the world changes dramatically to deal with a warming planet, according to a landmark report.

The IPCC report, however, shows that global warming impacts have come sooner and hit harder than predicted.

The targets rely on increased use of renewable energy, to the point that they product 70 to 85% of electricity supplies by 2050.

They will also require considerable political engagement globally, as will reducing the amount of carbon being emitted.

What Will We See Once Global Warming Is Limited To 1.5C?

Scottish Greens' co-convener Patrick Harvie said: "We've always challenged the government to go further in its response to unsafe climate change".

"Climate impacts are exponentially more dramatic when we go from 1.5C to 2C", said Henri Waisman, a scientist at the Institute for Sustainable Development and International Relations, and a coordinating lead author of the IPCC report.

The report explains why it's so important that we meet the 1.5 degree target, and how hard that will be to accomplish.

When water heats up, it expands meaning when oceans likely continue to rise, the IPCC says, we can expect the oceans to rise between 28 to 98cm by 2100, enough to swamp numerous cities along the USA east coast.

McKibben believes the odds of governments taking action in the wake of this report are slim.
