		<description>	&lt;p&gt;Medicare, daycare, welfare, jobfare.â€¦.&lt;br /&gt;
Greenzi sustainability is &lt;span class=&quot;caps&quot;&gt;POVERTY&lt;/span&gt;.&lt;br /&gt;
Global Warming, the new &lt;span class=&quot;caps&quot;&gt;WMD&lt;/span&gt; scam of fear and lies.&lt;/p&gt;

	&lt;p&gt;At first they just came for the light bulbs and I did not speak out.&lt;br /&gt;
Because these days, I like to hide out in the darkness of my nice warm basement.&lt;/p&gt;

	&lt;p&gt;Then they came for the plastic bags and I did not speak out.&lt;br /&gt;
Because I was already using the replacement bag they had issued to me as per the minimum consumption laws made of 100% Polyester (imitation weave no less).&lt;/p&gt;

	&lt;p&gt;Then they came with this giant, tandem diesel powered monster of a truck to pickup and compost my â€œbaggedâ€ leaves and I did not speak out because I didnâ€™t have any bags.&lt;br /&gt;
So they issued me their new paper bags with 100% of the 30% portion being recycled paper, or a 70% loss in real trees.&lt;/p&gt;

	&lt;p&gt;Then they came for my oil and I did not speak out.&lt;br /&gt;
Because they had already confiscated my Smartcar and recycled it into a wheelbarrow that they forced me to use every Earth Day to help them discover new sites to plant more and more and more trees.&lt;/p&gt;

	&lt;p&gt;Then they came for the &lt;span class=&quot;caps&quot;&gt;BBQ&lt;/span&gt; and I did not speak out.&lt;br /&gt;
Because it doesnâ€™t matter what the F*&amp;% you do to a vegetarian hotdog, it still tastes like $hit.&lt;/p&gt;

	&lt;p&gt;Then they came for the air conditioner and I did not speak out.&lt;br /&gt;
Because by this time, the inevitable cool climate trend had cycled in once again as it has for billions of eons all by itâ€™s poor little self, for reasons we do not and may not ever understand.&lt;/p&gt;

	&lt;p&gt;Then they came to register me to vote, and I did not speak out.&lt;br /&gt;
So they impaled my poor little weed infested, pesticide free front lawn with one of their plastic Green Party reelection signs.&lt;/p&gt;

	&lt;p&gt;Finally they came for me and I &lt;span class=&quot;caps&quot;&gt;COULD&lt;/span&gt; not speak out.&lt;br /&gt;
Because there was nothing left to give, or take.&lt;/p&gt;

	&lt;p&gt;Our children will not be suffering a hell on earth on a toxic melting planet after all because the theory of humans destroying planets with C02 (one of the building blocks of life) has been proven false since it is 25 years old now. &lt;br /&gt;
â€œSustained, unprecedented and escalating warmingâ€ -&lt;span class=&quot;caps&quot;&gt;IPCC&lt;/span&gt;&lt;br /&gt;
Be happy and learn to respect nature, not fear for it.&lt;br /&gt;
&lt;span class=&quot;caps&quot;&gt;STOP&lt;/span&gt; &lt;span class=&quot;caps&quot;&gt;THE&lt;/span&gt; &lt;span class=&quot;caps&quot;&gt;PANIC&lt;/span&gt;:&lt;br /&gt;
1-There IS debate.&lt;br /&gt;
2-The theory is 25 years old.&lt;br /&gt;
3-La Nina is stronger than global warming the theory now admits.&lt;br /&gt;
So preserve our environment, not rescue it with fear from a non-existent crisis.&lt;br /&gt;
Contribute to the advancement of our civilization to use nuclear power to fuel electric cars instead of going back in time to live with less. &lt;br /&gt;
We are living longer than at any time in human history and there is no reason for this not to continue if we just learned to embrace the future with optimism, not terror.&lt;/p&gt;

		<description>	&lt;p&gt;Years ago it became quite clear that malignant forms of power and greed had invasively overtaken those with great wealth as well as their bought-and-paid-for politicians in my not-so-great generation of leading elders. They perversely chose to mortgage the very future of our children. If that had been the end of their shameless behavior, things would have been bad enough. But no, it now appears these leaders, for whom honesty, transparency and accountability are everywhere eshewed, have gone a step beyond merely mortgaging the children&#039;s future. They are surely thieves of the highest order because they are threatening to steal the children&#039;s future by effectively extirpating â€œlife as we know itâ€ and destroying the Creation for which all of us â€” rich and poor, arrogant and meek, powerful and powerless â€” bear responsibility.&lt;/p&gt;

		<description>	&lt;p&gt;Dear Skip Walker and research team members,&lt;/p&gt;

	&lt;p&gt;Thanks for the work you are doing. In the long run scientists prevail and ideologues fail.&lt;/p&gt;

	&lt;p&gt;Despite all the complexities of modern life, it seems to me that unvarnished and unreflective support of three primary behaviors are governing the &#8220;way of life&#8221; of most people in our culture. These widely shared and consensually validiated behaviors literally drive unbridled growth of production capabilities, unrestrained per human consumption of resources, and unbounded hubris. The leviathan scale and anticipated rise of these objective and subjective all-too-human tendencies could become patently unsustainable soon; whereas, setting limits on the increasing growth of uneconomic production, unhealthy overconsumption, unrestricted population numbers and unconscionable, objectively unjustifiable arrogance could lead the human community toward sustainable ways of living in the world.&lt;/p&gt;

	&lt;p&gt;Perhaps necessary change is in the offing.&lt;/p&gt;

		<description>	&lt;p&gt;(Faith Based Science)&lt;br /&gt;
The End Is Near &lt;/p&gt;

	&lt;p&gt;We have seasons, and weather in a climate that varies unpredictably and is little understood. Even the &#8220;scientists&#8221; say that it is very challenging research with so much more to learn about climate.&lt;br /&gt;
With that in mind, if we don&#8217;t understand natural climate, how are we going to be to be able to tell the difference form it and so-called human induced weather? What gives us the rite to say that any climate including for that matter is anything &lt;span class=&quot;caps&quot;&gt;BUT&lt;/span&gt; natural? Climate is not like the inside of a nice indoor shopping mall and this sense of urgency over a nothing crisis is something I hope we as a society grow out of. The dirty thirties put things in perspective and people of that time would never have even given this 23 year old theory a second glance in the first place. Now we have medicare, day care, health care, job fares&#8230;&#8230;&#8230; . We have had things so good for so long that we don&#8217;t know what bad is. That&#8217;s why the global warming craze has been so enduring and successful at tapping our collective guilt.&lt;br /&gt;
So life goes on, no crisis, it melts, it freezes, we have record hurricanes one year and none at all the next, North America has been cooling for a decade.&lt;br /&gt;
I say we all be thankful that CO2 is not a pollutant after all and therefore we should all tackle real pollution, keeping in mind that environmentalism&#8217;s accomplishments have been many and our world has improved from that success over the last 40 years. Have a parade. Let&#8217;s all be happy with clear perspective without the politics.&lt;/p&gt;

		<description>	&lt;p&gt;Notice the people who are for it are using rhetoric to make it seam more convincing and smarter but I do not see a connection between some bodies of water warming and some colling and some getting greener. Also I notice only negaTIVES OF &lt;span class=&quot;caps&quot;&gt;GLOBAL&lt;/span&gt; &lt;span class=&quot;caps&quot;&gt;WARMING&lt;/span&gt; &lt;span class=&quot;caps&quot;&gt;MAKING&lt;/span&gt; IT SO &lt;span class=&quot;caps&quot;&gt;BAD&lt;/span&gt;&#8230; who knows maybe if you look at all the details a warmer Earth is better. And dont tell me the polar bears will die because if they do then they were weak and could not adapt. bah i could go on rambling all the possible theories just like the global warming dudes. I trust in God not some humans who try to predict weather in 50 years but cant even do 3 days.&lt;/p&gt;

		<description>	&lt;p&gt;Dr. Walker,&lt;/p&gt;

	&lt;p&gt;Thank you for your excellent follow-up discussion on the data and methodologies behind your research. The short podcasts deliver the headline but often leave us science minded individuals wanting to know more details.  I think it is really cool that you took the time to give such a well articulated and detailed reply to Dan and Ben. I look forward to hearing more about your ongoing work (I bookmarked &lt;a href=&quot;http://www.geobotany.uaf.edu/sass/index&quot; rel=&quot;nofollow&quot;&gt;your web page&lt;/a&gt; to keep up on your &lt;span class=&quot;caps&quot;&gt;SASS&lt;/span&gt; program).&lt;/p&gt;

	&lt;p&gt;I wanted to point out to other commenters that you are using the &lt;span class=&quot;caps&quot;&gt;AVHRR&lt;/span&gt; based sensors on the &lt;span class=&quot;caps&quot;&gt;NOAA&lt;/span&gt;-11 and 12 satellites rather than the failing &lt;span class=&quot;caps&quot;&gt;SSM&lt;/span&gt;/I sensors on board &lt;span class=&quot;caps&quot;&gt;DMSP&lt;/span&gt;-F13 and F15 which caused the recent data problems with &lt;span class=&quot;caps&quot;&gt;NSIDC&lt;/span&gt; real-time products. As such, the &lt;span class=&quot;caps&quot;&gt;NSIDC&lt;/span&gt; data errors would not impact your findings.&lt;/p&gt;

	&lt;p&gt;I understand that the &lt;span class=&quot;caps&quot;&gt;NDVI&lt;/span&gt; is calculated to approximately a month&#039;s resolution (to normalize for cloud cover, storms, low &lt;span class=&quot;caps&quot;&gt;SNR&lt;/span&gt; events, etc&#8230;). Thus, the MaxNDVI would be the month range of highest photosynthesis productivity for the year (as opposed to a fixed sample month each year) if I understand your comments.&lt;/p&gt;

	&lt;p&gt;Is the scope of your research focused mainly on the correlation specifically between greenness and observed coastal land temperatures or are you collaborating with other research groups to correlate to oceanic, atmospheric, solar, and geologic processes which drive the region&#039;s climate variability so that those drivers can be used as longer range predictors?&lt;/p&gt;

<p>Thank you for your excellent follow-up discussion on the data and methodologies behind your research. The short podcasts deliver the headline but often leave us science minded individuals wanting to know more details.  I think it is really cool that you took the time to give such a well articulated and detailed reply to Dan and Ben. I look forward to hearing more about your ongoing work (I bookmarked <a href="http://www.geobotany.uaf.edu/sass/index" rel="nofollow">your web page</a> to keep up on your <span class="caps">SASS</span> program).</p>
<p>I wanted to point out to other commenters that you are using the <span class="caps">AVHRR</span> based sensors on the <span class="caps">NOAA</span>-11 and 12 satellites rather than the failing <span class="caps">SSM</span>/I sensors on board <span class="caps">DMSP</span>-F13 and F15 which caused the recent data problems with <span class="caps">NSIDC</span> real-time products. As such, the <span class="caps">NSIDC</span> data errors would not impact your findings.</p>
<p>I understand that the <span class="caps">NDVI</span> is calculated to approximately a month&#8217;s resolution (to normalize for cloud cover, storms, low <span class="caps">SNR</span> events, etc&#8230;).

		<description>	&lt;p&gt;The author refuses to believe that the satellite that measures sea ice in the Artic suffered a sensor &lt;span class=&quot;caps&quot;&gt;GLITCH&lt;/span&gt; and missed over 190,000 sq. miles of sea ice or maybe this glitch wasn&#8217;t supposed to be made public by the Melting ice activist.&lt;/p&gt;

		<description>	&lt;p&gt;Melting ice, pictures of polar bears and falling ice do not &lt;span class=&quot;caps&quot;&gt;CAUSE&lt;/span&gt; climate change. This is insanity. History is already laughing.&lt;br /&gt;
Follow the link to:&lt;br /&gt;
Fire James Hansen â€“ &lt;span class=&quot;caps&quot;&gt;NASA&lt;/span&gt; Climate Chief in Facebook groups.&lt;br /&gt;
We need responsible environMENTALism, not to mention science.&lt;/p&gt;
