More bad news for the alarmists to "wine" about., page-467

the following is the start of a letter signed by at least 370 scientists in Australia calling for action from govt to create and implement policies that will contribute to global action to mitigate the imminent effects of human activity on climate change.

the start of the letter follows the headline below.

”There is no strong, resilient Australia without deep cuts to greenhouse gas emissions

”An open letter on the scientific basis for the links between climate change and bushfires in Australia.

”This open letter is supported by 370 scientists with research expertise across the fields of climate, fire and weather science. This open letter is composed of the full statement, a summary statement, and lists of co-signatories and references.

3rd February 2020.


“Executive summary and call for action

”Scientific evidence unequivocally links human-caused climate change to the increasing risk of frequent and severe bushfires in the Australian landscape. That same science tells us these extreme events will only grow worse in the future without genuine concerted action to reduce global emissions of greenhouse gases.

”We, the undersigned climate, weather and fire scientists, call on our country’s leaders and policymakers to develop science-informed policies to combat human-caused climate change. To be successful, these policies must urgently reduce Australia’s total greenhouse gas emissions and lead to constructive engagement and agreements with other world leaders for coordinated global climate action.

”We call on our leaders to unite to develop non-partisan, long-term policies that will enable the managed transition to net zero greenhouse gas emissions by 2050 that the scientific evidence shows is required to avoid dangerous human-caused climate change.

”The science is clear. It is time to show leadership and set a clear path to protect our country and way of life for future generations.

”This statement summarises the scientific basis for the links between climate change and bushfires in Australia, and the climate action that is required to limit further worsening of our bushfire risk and build a stronger and more resilient Australia.“

”Key points:

”Human-caused climate change is worsening fire-weather and bushfires in southern and eastern Australia.

”Observations show a trend towards more frequent and extreme fire-weather conditions during summer, and an earlier start to the fire season, particularly in southern and eastern Australia.

”Australia’s year-to-year climate variability is being altered by climate change. This variability, combined with regional rainfall trends and human-caused warming, contributed to the extremely dangerous bushfire conditions this summer.

”Dry fuel loads related to widespread drought provided conditions for extensive burning in the 2019/20 bushfires.

”Australia’s dangerous fire-weather is virtually certain to worsen in the future with ongoing human-induced climate change, making fire management increasingly challenging.

”Australia is part of the Paris Agreement and has a commitment to pursue efforts to limit warming to 1.5°C above pre-industrial levels, which would significantly reduce the intensification of Australia’s bushfire risk along with many other climate change risks. The current emission reduction targets of Australia and the world are insufficient and will commit us to 3°C or more of warming by the end of this century.

”The scientific basis

”The severity, destructiveness and unprecedented scale of the 2019/20 bushfires in eastern and southern Australia1 have generated public discussion on the role of climate change in this crisis. This statement summarises the scientific knowledge on how human-induced (anthropogenic) climate change is affecting bushfires in Australia.

”Human-caused climate change is increasing the risk of fires in various regions of the world, including Australia2-6.

”Fire activity is controlled by four limiting factors7:
” (i) a fuel load (vegetation biomass); (ii) the fuel being dry enough to burn; (iii) an ignition source (anthropogenic or lightning); and (iv) weather that is conducive to carrying that fire through the landscape (e.g. high temperatures, wind speed and low humidity). Climate influences all four of these factors7-10.
