15,000 scientists issue 'warning to humanity'

Thousands of scientists from 184 countries have issued a stark warning about the future of our planet.
The warning, which comes 25 years after a mere 1,500 scientists issued a similar warning in 1992, has been trending on Twitter with the hashtag #ScientistsWarningToHumanity.

The campaign was started by William Ripple of Oregon State University's College of Forestry who, along with graduate student Christopher Wolf, conducted a revised analysis of each of the concerns that had been raised a quarter of a century ago.

With the exception of a rapid decline in the rate of ozone depletion, the findings were grim.

In addition to climate change, Ripple highlighted multiple environmental concerns including ocean dead zones, dwindling biodiversity, forest losses and unsustainable marine fisheries.

"The trends are alarming, and they speak for themselves," he said.

"The scientists around the world are very concerned about the state of the world, the environmental situation and climate change. So this allows them to have a collective voice."

Co-author Professor Eileen Crist also echoed the concerns highlighted in the report.

"We are in the throes of a mass extinction event that is anthropogenic," she said. "If we lose 50 to 75 per cent of the species on the planet in this century - which is what scientists are telling us what will occur if we continue to operate as business-as-usual. If this happens, this can not be fixed."

I tried that.  Lots of complaints from my neighbor about the dandelions.  I offered to let him dig them up.  Needless to say, they're still there. I did mow it, about three times a year.  And I try to rake up the leaves about once a year, but with trees all over the neighborhood, that's a hopeless task. At least, my dogs and kids don't get cancer from playing in the yard. Doug

Earth will be fine. It will be around for another 4.5 billion years or so.

Pollution concerns is not the same as apocalyptic scare mongering so some people can make some money.

LOL, the whole goal of science is understanding our physical world so we can predict the future when certain things happen.  One of the major aspects of the scientific method is observation after an hypothesis is made.  We have all the apocalyptic hypothesis that the scientists have concocted to try to understand these natural forces but when we go to try to observe whether these hypotheses are correct we find there's no evidence to support them.  That is unless we lie and change the historic climate data or change the measurements of the current climate data.  It's just plain BAD SCIENCE as i...

There are almost 100 global climate models that have been around long enough for observational verification through the scientific method.  Zero percent of them have correctly observed and verified their climate hypothesis under the scientific method for the current climate data without either modifying the current raw climate measurements or modifying the decades old historic climate data.  That's not verification, that's changing the data to say what you want it to say. Global climate has been warming since the 1700's so it's not really something that needs to be proved as it's easily observ... [More]

Corporations today are all linked by the same fabric and for it to continue in their favor, its necessary to create various types of on-going scenarios for the the public to gobble up, digest and spit out. In the process of all of this the main goal has been to sell, sell and keep selling whatever it is that pertains to whatever subject of interest at that time. Aquifers world wide aren't owned by the small guy...and this commodity will soon be the world's number one in the very near future if just one country should decide to use any type of nuclear weapon on another.  On the other hand, the ...

Please give me an example of what you're talking about. What phenomena, which hypothesis failed and why it "failed the scientific method". An example of where historical climate data has been changed would be good too. Not trying to trap you, just want examples of what you're talking about. Its very easy to fling accusations around, but around here you need to back them up.

Can you cite this please. And don't do the usual thing of telling me to "look on the internet".

Once again:  if a model does the job it's supposed to do, then it is successful. Climate models are scientific learning tools.  When they do not produce results consistent with observations, they show us where to do more research.  That's their job.  They are not weather-forecasting tools. Within ten years we should begin seeing GCMs that are accurate enough to use for local forecasts.  Things like:  how much water will this storm drain have to handle?  How high do the abutments on this bridge have to be?  Can we build a flat-topped building in Minneapolis?  These are based on forecasts of the...
