Without real change, the world is not even on course to reach the 2C target, according to the Intergovernmental Panel on Climate Change (IPCC) report, the main scientific guide for governments on how to implement the Paris Agreement.
The report fired up activists even as critics dismissed the deadline as another arbitrary "climate tipping point", as Climate Depot's Marc Morano put it.
Society would have to enact "unprecedented" changes to how it consumes energy, travels and builds to meet a lower global warming target or it risks increases in heat waves, flood-causing storms and the chances of drought in some regions, as well as the loss of species, a United Nationsreport said yesterday.
Junaid Ahmad, Country Director, the World Bank, said the world is relying on India more than before to address the challenges of climate change.
"The window on keeping global warming below 1.5 degrees C is closing rapidly and the current emissions pledges made by signatories to the Paris Agreement do not add up to us achieving that goal", said King. Average temperatures rose by 0.12 of a degree per decade from 1885 to 2017. Instead, it risks setting up feedbacks that could fall like risky dominos, fundamentally destabilizing the planet.
Former George Tech atmospheric-sciences professor Judith A. Curry described the report's conclusions as the "same old, same old", based on questionable climate models and not "new science or better ways of assessing uncertainty".
These cascading feedbacks include the loss of the Arctic's sea ice, which could disappear entirely in summer in the next 15 years. The stains contribute to warming, because the darkened snow absorbs more heat instead of reflecting it. "We are already putting all our efforts to ensure that the global temperature does not further increase". This, in turn, would accelerate the collapse of permafrost, releasing its ancient stores of methane, a super climate pollutant 30 times more potent in causing warming than carbon dioxide. These wildcards could very likely push the climate system beyond human ability to control.
Petteri Taalas is Secretary-General of the World Meteorological Organization. And just Monday, the Trump administration announced that the Environmental Protection Agency would be changing a rule to allow year-round sales of E15, or fuel that is 15 percent ethanol by volume. 'While it's technically possible, it's extremely improbable, absent a real sea change in the way we evaluate risk.
The warning: Governments need to take "rapid, far-reaching and unprecedented changes in all aspects of society" to avoid the disastrous effects of global warming, the report says. Including a goal that by 2030 all new buildings will be built to produce near-zero greenhouse gas emissions.
Action in cities - which consume more than two-thirds of energy globally and account for about three-quarters of carbon emissions - are pivotal to meeting the target, said report author William Solecki, a professor at Hunter College-City University of NY.
Global temperature is now rising 0.2C with each decade, and it is estimated we will reach 1.5C by 2040.
Mayor John Tory campaign spokesperson Keerthana Kamalavasan said in a statement that Tory is "committed to fighting climate change". But above all, it is an issue we can still do something about.
President Trump announced in June he would pull out of the Paris accord, saying it would put the USA economy at a global disadvantage. These three leaders have the potential to provide Churchillian leadership to stabilize the world's climate, starting by rallying the G20 countries responsible for 80 percent of the problem.
The new report sets those levels much lower and measures devastating climate change effects much sooner.
The Sydney Opera House is not a 'billboard': Shorten
On Friday's 2GB Breakfast show Jones repeatedly yelled "we" own the Opera House over the top of his interview subject. Racing NSW had also wanted to list horse names on the Opera House sails, but that will not happen.
