By midcentury, we have to reach net zero emissions. With the new numbers in, experts say it's up to lawmakers to act. "But it will require unprecedented and collective climate action in all areas". We ourselves are also making sure we take action at the national and Pacific regional level with actions to reduce our greenhouse gas emissions. It would mean a carbon-neutral world - one with no net additional greenhouse gases in the atmosphere - by 2050.
"Considering the urgency to rapidly decarbonise, the world needs a "Plan B", as the Plan A - the Paris Agreement - will push the world towards catastrophic warming".
The IPCC report, however, shows that global warming impacts have come sooner and hit harder than predicted.
A 1.5C world will bring huge challenges to the Pacific, our people and our ecosystems. One was, what would be the impacts of global warming of 1 1/2 degrees compared with global warming of 2 degrees? When figures came out in the past few years noting that more than 500 million plastic straws were being used daily in the US and they were polluting the ocean, local government after local government quickly moved to ban plastic straws.
The consequences of a 2 degrees rise in global warming will be devastating scientists have warned.
Even with a temperature increase of 1.5C, coral reefs are expected to decline by 70-90 per cent. But if warming stops at 2 degrees, more than 99% of reefs could disappear. 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 temperatures to below 1.5°C by 2100. Fewer ecosystems would be irreversibly lost.
Impacts ranging from increased droughts and water scarcity to extreme weather, spread of diseases such as malaria, economic damage, and harm to yields of maize, rice and wheat will be less severe at 1.5C than 2C. It could prevent as many as 2.5 million square kilometers of permafrost from melting over the long term. Why shoot for 1.5 degrees?
The promises countries have made so far to cut their emissions would put the world on track for 3°C of warming by the end of the century.
The World Coal Association noted the IEA and other forecasters expect the fuel to remain an important part of the energy system for the foreseeable future.
The report landed on the same day that the Nobel Committee awarded the Nobel Prize in Economics to two American scientists for their work highlighting the role of government policy in promoting sustainable economic growth.
While there are steps to be taken they do need ambitious leaders who are willing to take "rapid and far-reaching" means in all aspects of society from land management, energy, industry, buildings, transport, and cities.
KING: So we need more than what has been agreed upon, more than the nations that have set goals aimed at limiting warming of the planet have said.
A special report on limiting global warming, released by a United Nations scientific panel on October 8, should be heard around the world as an "ear-splitting wake-up call" said United Nations chief António Guterres. "Each year that the global economy fails to decarbonize at the required rate, the two-degree goal becomes more hard to achieve".
What does the report say? We've got to 1 degree today. "But I would say the biggest obstacle really is political will". Is now the time to call on government for legislation to go further?
Issued two months before the worldwide climate talks in Katowice, Poland, the report provides a timely input for the Commission's proposal for a strategy for long-term European Union greenhouse gas emissions reductions, to be presented in November, the EC said on October 8.
