Landmark UN climate report warns time quickly running out

Rising sea levels cause flooding at high tide near the airport runway

The WWF called on the European Union to take urgent action to limit global warming to 1.5ºC, saying in a press release: "Approved by 195 governments, the report underscores the small window of opportunity we have to make immediate, deep and transformational changes - without which the world we know will be irreversibly changed".

The headlines about cutting emissions by 45% by 2030 and getting nearly all of our electricity from renewables by the middle of the century, are all very well but a key point of this report is that successfully limiting climate change to 1.5C is not just down to cutting emissions or making lifestyle changes or planting trees - it is all of that and then some, acting in concert at the same time. The report draws on research conducted since nations unveiled the 2015 Paris climate agreement, which seeks to curb greenhouse-gas emissions and limit global temperature increase to between 1.5 and 2 °C.

An Associated Press article poignantly captures what the IPCC said in its "gloomy" report: That "preventing an extra single degree of heat" - meaning the 2 degrees C mark - "could make a life-or-death difference in the next few decades for multitudes of people and ecosystems on this fast-warming planet". By 2050, they will need to reach "net zero" - any further CO₂ emissions due to human activity would then have to be matched by deliberate removal of CO₂ already in the atmosphere, including by planting trees.

The IPCC report says we need "rapid and far-reaching" changes in energy systems, land use, city and industrial design, transportation and building use. We expect to lose 75 to 90 percent of coral reefs by 1.5°C; at 2.0 °C, that number is over 99 percent.

He said: 'We know what is needed to limit global warming to 1.50C and we can do it relying mostly on proven technologies such as decisively scaling up renewable energy and halting deforestation.

"International cooperation is absolutely imperative to limit emissions and therefore global warming and its impacts, as well as coordinating effective and widespread adaptation and mitigation", said Sarah Perkins-Kirkpatrick, a fellow at the Climate Change Research Center at the University of New South Wales.

The report is seen as the main scientific guide for government policymakers on how to implement the 2015 Paris Agreement during the Katowice Climate Change Conference in Poland in December.

The world has reached a fork in the road with two paths ahead: a planet that's 2°C warmer than pre-industrial levels and a planet that's 1.5°C warmer.

The report notes that we are now at a warming of about 1.0°C, with the warming trend rolling along at 0.2±0.1°C per decade.

In its landmark report, the United Nations has warned that time is running out to avert disaster, adding that avoiding global climate chaos will require a major transformation of society and the world economy that is "unprecedented in scale".

That could reduce flooding and give the people that inhabit the world's coasts, islands and river deltas time to adapt to climate change.

"Scientists are increasingly aware that every half degree of warming matters", Chris Weber, WWF's global climate and energy lead scientist, said in a statement.

The effectiveness of such techniques are unproven at large scale and some may carry significant risks for sustainable development, the report notes. "The next few years are probably the most important in our history", she said.

Neither Premier Ford nor Mr. Kenney have yet said what policies they would employ to cut emissions, or whether they support Canada's objective of reducing greenhouse gas emissions by 30 per cent below 2005 levels by 2030 - a commitment made under the Paris accord.

"The science in the IPCC report on 1.5°C speaks for itself". This will mean a lot for our ability to bring you news, perspectives and analysis from the ground so that we can make change together.

Global Warming of 1.5 °C is the first in a series of Special Reports to be produced in the IPCC's Sixth Assessment Cycle.

At the same time, however, the Liberals are supporting major projects that will increase Canada's capacity to export oil and gas for decades, including expansion of the Trans Mountain crude pipeline and construction of a liquefied natural gas terminal in Kitimat, B.C.

The report further revealed that global warming has already had an effect in regions across the world.
