"The next few years are probably the most important in human history", Debra Roberts, head of the Environmental Planning and Climate Protection Department in Durban, South Africa, and an IPCC co-chair, told AFP. For example, with 1.5 degrees C of warming, sea levels are projected to rise 26 to 77 centimeters by 2100; going to 2 degrees C adds another 10 centimeters, which would affect an additional 10 million people living in coastal regions.
Keeping the 1.5C target would keep the global sea level rise 0.1 metre lower by 2100 than a 2C target, the report states.
The likelihood of an Arctic Ocean free of sea ice in summer would be once per century with global warming of 1.5 °C, compared with at least once per decade with 2 °C. 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.
"We welcome the conclusions of this historic report, one that should give the worldwide community not just a wake-up call, but also hope that we can avoid the most devastating impacts of climate change", said Bill Hare, Climate Analytics CEO.
The IPCC report suggests that limiting global warming to 1.5°C instead of 2°C would make a huge difference for the life in oceans and land. Scientists, including some from the Indian Institute of Technology Delhi, had at the time already sounded alarms over climate change as they said it had "exacerbated" the heat wave in the country. The United States already leads the world in reducing carbon-dioxide emissions.
"The government will take into account. the recommendations of the [council] and. the IPCC's special report to draw up Hong Kong's long-term decarbonisation strategy up to 2050 by the end of 2019 or early 2020", the spokesman said.
The report is sensitive to the fact that changes required to meet 1.5℃ must be consistent with the UN's wider sustainable development goals.
"This report is not a wake-up call, it is a ticking time bomb", said Gro Harlem Brundtland, Acting Chair of The Elders in a statement.
The report found that if greenhouse gas emissions continue to grow at their current rate, the earth's atmosphere will warm up by as much as 1.5ºC above pre-industrial levels by 2040.
Should governments fail to do that within a decade, and temperatures rise more than 1.5 degrees C, there's one more Hail Mary option.
Pompeo Faced Hard Bargain From the Start of His North Korea Trip
Korean Central News Agency ( KCNA ) reported that Kim had "warmly welcomed" Pompeo in Pyongyang and "spoke highly of him". US officials have thus far said the penalties will remain in place until the North's denuclearization is fully verified.
This report shows the longer we leave it to act, the more hard, the more expensive and the more risky it will be.
The feasibility of solar, wind and battery storage has improved significantly in recent years, which could signal the system is transforming, the report says.
Climate Analytics is a global research organisation whose scientists have extensively contributed to the literature on which the IPCC has based its SR1.5 assessment.
"This is a pivotal part of turning back the climate change siege", he said.
Climate scientists warn that these goals probably won't be met without some serious new technological firepower created to suck greenhouse gases back out of the air.
But evidence in the new report, in which a team of 91 scientists from 40 countries analyzed over 6,000 scientific studies, shows that the future is bleaker than once thought.
The landmark Paris Agreement adopted in December 2015 by 195 nations at the 21st Conference of the Parties to the UN Framework Convention on Climate Change (UNFCCC) included the aim of strengthening the global response to the threat of climate change by "holding the increase in the global average temperature to well below 2°C above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels". "If action is not taken it will take the planet into an unprecedented climate future".
"It also confirms that the Paris Agreement commitments fall far short of what is needed".
The week-long meeting in Incheon, South Korea - already deep into overtime - deadlocked on Saturday when oil giant Saudi Arabia demanded the deletion of a passage noting the need for global Carbon dioxide emissions to decline "well before 2030". Now we find out whether governments will do anything with that knowledge. Considering that such techniques could save us even in the event that we overshoot the 1.5-degree-Celsius mark, this route sounds pretty appealing.
