into irreversible climate change?

But it's important to emphasize that if southwest North America moves
into a dust bowl by mid-century or later (PNAS
Irreversible climate change due to carbon dioxide emissions, http://www.pnas.org/content/early/2009/01/28/0812721106.full.pdf+html), there will be suffering closer to home, even for people on other parts of the continent.
In the report released today by the Intergovernmental Panel on
Climate Change, the world's top scientists warned that global warming is unequivocally man - made and will become

into the atmosphere.
While forecasting the state of the environment more than 80 years
into the future is a notoriously inexact exercise, academics gathered by the the United Nations at the Intergovernmental Panel on
Climate Change are concerned the world is headed for «extensive» species extinctions, serious crop damage and
irreversible increases in sea levels even before Trump started to unpick the fight against global warming.
Where there are threats of serious or
irreversible damage, lack of full scientific certainty should not be used as a reason to postpone such measures, taking
into account that policies and measures to deal with
climate change should be cost - effective in order to ensure global benefits at the lowest possible cost.
The spewing of 110 million tonnes a day of heat - trapping pollution
into the atmosphere — as if the atmosphere were an open sewer — is «increasing the likelihood,» says a warning from the Intergovernmental Panel on
Climate Change, «of severe, pervasive and
irreversible impacts for people and ecosystems».
Where there are threats of serious or
irreversible damage, lack of full scientific certainty should not be used as a reason for postponing such measures, taking

climate change should be cost - effective so as to ensure global benefits at the lowest possible cost (UN 1992a: Art 3, emphasis added).
Ah yes, it's always a good idea to squeeze «abrupt and
irreversible»
into alarmist reports on
climate change.
Yet as we said at the time, this highly ambiguous statement made it
into the headlines — with the help of senior IPCC members — as a statement that «The IPCC states that
climate change is «unequivocal» and may bring «abrupt and
irreversible» impacts».
Whether you (or Edim) personally want to worry about these things is up to you, my point is that there are plenty of potential effects of
climate change which would not fall
into the «abrupt and
irreversible» category but could still cause big problems if they occur, so just because the particular outcomes the IPCC classifies as such may not happen this century it doesn't logically mean we won't suffer serious impacts in the shorter term.
STOCKHOLM — The world's top
climate scientists on Friday formally embraced an upper limit on greenhouse gases for the first time, establishing a target level at which humanity must stop spewing them
into the atmosphere or face
irreversible climatic
changes.
