United Nations Climate Report Warns Miami Basically Screwed

And, in Norfolk, the Green Party says all levels of government, including local councils, need to heed the warning from the scientists who put together the report.

The IPCC, the UN's top climate panel, issued the report from Incheon, Republic of Korea, where for the past week, hundreds of scientists and government representatives have been pouring over thousands of inputs to paint a picture of what could happen to the planet and its inhabitants with global warming of 1.5°C (or 2.7 degrees Fahrenheit).

The science shows that a 2C rise will lead to greater sea level rises, more heatwaves and extreme rainstorms, more people facing water shortages and drought, lower yields for some crops and greater impacts on wildlife than 1.5C. Coral reefs would decline by 70-90 percent with global warming of 1.5 °C, whereas virtually all ( 99 percent) would be lost with 2 °C. The longer we wait to act, the IPCC report says, the more we'll have to use this type of technology, which has never been proven at a large scale.

They tell how global warming of more than 1.5°C will be a huge risk and to prevent it we ... that's the whole world ... must halve our emissions in 10 years.

Now, how different would the world look if we managed to limit man-made warming to half-a-degree, instead of 1 degree C? Trillions of dollars will soon be invested in new infrastructure; if we make the wrong choices, they'll be locked in, according to the same recent report.

"While the pace of change that would be required to limit warming to [2.7º F] can be found in the past, there is no historical precedent for the scale of the necessary transitions, in particular in a socially and economically sustainable way", the report stated.

If greenhouse gas emissions are not cut drastically and rapidly, between 2030-52, Earth's global average temperatures could rise by 1.5 degree above pre-industrial era levels, leading to widespread climate change impacts.

That's the conclusion of a new report by the UN's Intergovernmental Panel on Climate Change (IPCC).

Limiting warming to 1.5°C is possible within the laws of chemistry and physics but doing so would require unprecedented changes, Co-Chair of IPCC Working Group III Jim Skea said.

Monday's report was produced by three IPCC working groups. Temperatures on extreme hot days in mid-latitudes could increase by 3 °C with 1.5 °C of global warming, versus 4 °C in a 2 °C world.

Phoenix Suns relieve Ryan McDonough as general manager
The Phoenix Suns announced today that they have relieved Ryan McDonough of his role as general manager, effective immediately. Last year's 21-61 record was the worst in the National Basketball Association and second-worst in franchise history.

On a jarring note, the U.S. announced that it accepted the report - in effect stopped short of vetoing it - but it did not endorse the content and the findings in the report.

The world has only a few years left to deal with climate change - or face blistering heat waves, rising seas and a 'shocking rise in hunger, ' a United Nations report has warned. But even though the world has already warmed by 1 °C, humanity has 10-30 more years than scientists previously thought in which to kick its carbon habit.

The Summary for Policymakers (SPM) presents the key findings of the Special Report, based on the assessment of the available scientific, technical and socio-economic literature relevant to global warming of 1.5 °C.

"We also need more effective harmonised regulatory processes to facilitate significant growth in nuclear capacity and an effective safety paradigm where the health, environmental and safety benefits of nuclear are better understood and valued by society".

IPCC is the United Nations body for assessing science related to climate change. Although the report says that emissions would not be the sole contributor to temperatures above 1.5°C, the future rates of emission reductions will determine whether temps rise.

Measures would have to include reducing man-made carbon emissions by 45 per cent by 2030 from 2010 levels, and reaching "net zero" emissions by 2050, the report said.

Limiting warming to 0.5 degrees from now means the world can keep "a semblance" of the ecosystems we have.

It would also require developed countries to contribute more to global finance flows and technology sharing for poor countries to achieve these enhanced targets.

"The government does have a bit of a love affair with coal and see the use of coal in Australia going on forever", she said.
