The researchers further recommend that, given that many human influences are
driving both
climate change and biodiversity loss, conservationists should aim for win - win solutions such as the United Nations program REDD + (an extension of the Reducing Emissions from Deforestation and forest Degradation programme)-- an initiative that protects forests while also creating benefits for
local communities and biodiversity.
These trends suggest that large - scale
climate changes, rather than
local factors, could be
driving increases in fire activity, the scientists report.
The water crisis is being
driven by several factors:
climate change, an expanding population,

So we have the national «liberal» media, like the NYT and NBC, blowing this story, while the
local, conservative media get it right, see «conservative San Diego Union knows
climate change is killing Western forests» and «Oldest Utah newspaper: Bark - beetle
driven wildfires are a vicious
climate cycle.»
That matters because the trickiest part of global
climate models appears to be how they handle ocean - atmosphere interactions, and I really have no idea how well they link
changes in
local wind -
driven upwelling to the net thermohaline circulation.
Has your
local weather forecaster ever weighed in on human -
driven climate change, or has he or she avoided stepping into such politically charged terrain?
In the rekognition of the uncertainties, the IPCC Good - Practice - Guidance - Paper on using
climate model results offers some wise advice (first bullet point under section 3.5 on p. 10): the
local climate change scenarios should be based on (i) historical
change, (ii) process
change (e.g.
changes in the
driving circulation), (iii) global
climate change projected by GCMs, and (iv) downscaled projected
change.
The analysis also follows the advice in the IPCC Good - Practice - Guidance - Paper on using
climate model results: the
local climate change scenarios should be based on (i) historical
change, (ii) process
change (e.g.
changes in the

In the past few years, unusually warm air in the Arctic has
driven winter storm tracks south into the United States, reflecting the complex and sometimes counteracting ways that
climate change may affect
local weather extremes.
... «When you hear a phrase like he said, «the highest ever,» you know, «off the charts,» «record setting,» that's a good sign that on top of a whatever
local weather patterns there are or regional like El Nino, global warming, fossil fuel
driven climate change is putting its finger on the scale and juicing the atmosphere and causing the even bigger weather event than you would have otherwise seen.»
To address future challenges related to
climate change and land use, it will be important to assess the
local impacts of tree loss on
climate, climatic and ecological consequences, as well as the mechanisms that
drive ecological responses in remote teleconnected areas.
«Halting
climate change requires a global effort, but even
local actions can help with nutrient -
driven oxygen decline.»
Firstly, there is uncertainty about the future levels of greenhouse gas emissions
driving climate change [34] and considerable uncertainty in modeling how this will affect other aspects of
climate such as
local rainfall or temperatures.
You may wonder why the government finds the need to pursue such action since 1) U.S. carbon dioxide emissions have already topped out and have generally been on the decline for the past 7 - 8 years or so (from technological advances in natural gas extraction and a slow economy more so than from already - enacted government regulations and subsidies); 2) greenhouse gases from the rest of the world (primarily
driven by China) have been sky - rocketing over the same period, which lessens any impacts that our emissions reduction have); and 3) even in their totality, U.S. carbon dioxide emissions have a negligible influence on
local / regional / global
climate change (even a immediate and permanent cessation of all our carbon dioxide emissions would likely result in a mitigation of global temperature rise of less than one - quarter of a degree C by the end of the century).
The group discussed the ramifications of our fossil fuel
driven society and the impact of
climate change on
local communities.
