 <title>The Better Planet Guide quotes</title>
 <link>http://climate.the-organization.com/quotes</link>
 <description>We, the Human Race, are not really all that good for the Environment. Whether or not you believe in &quot;Climate Change&quot;, it is very hard to believe that our civilisation is not having a negative impact on the world around us. 
&lt;br\&gt;
Our objective with this site is not to debate whether or not climate change is a threat, it is to discuss ways in which we can improve the ability of our species to live on Planet Earth, without destroying it in the process.</description>

   &lt;p&gt;The mainstream scientific consensus on global warming&lt;a href=&quot;glossary#term14&quot; title=&quot;global warming: Global warming is a term used to describe an increase over time of the average temperature of Earth&amp;#039;s atmosphere and oceans. Global warming theories attempt to account for the rise in average global temperatures since the late 19th century (0.6 ± 0.2°C) and assess the extent to which the effects are due to human causes. The most common global warming theories attribute temperature increases to increases in the greenhouse effect caused primarily by anthropogenic (human-generated) carbon dioxide (CO2) and to possible increases in solar activity.

Climate models, driven by estimates of increasing CO2 and to a lesser extent by generally decreasing sulfate aerosols, predict that temperatures will increase (with a range of 1.4°C to 5.8°C for change between 1990 and 2100. Much of this uncertainty results from not knowing future CO2 emissions, but there is also uncertainty about the accuracy of climate models. Climate commitment studies predict that even if levels of greenhouse gases and solar activity were to remain constant, the global climate is committed to 0.5°C of warming over the next one hundred years due to the lag in warming caused by the oceans.

Although the discussion of global warming often focuses on temperature, global warming or any climate change may cause changes in other things as well, including the sea level, precipitation, weather patterns, etc. These may affect human activity via floods, droughts, heat waves, declining agricultural yields, etc.&quot; class=&quot;glossary-indicator&quot;&gt;i&lt;/a&gt;&lt;a href=&quot;glossary#term13&quot; title=&quot;climate change: The term climate change is used to refer to changes in the Earth&amp;#039;s climate. In the most general sense, it can be taken to mean changes over all timescales and in all of the components of climate, including precipitation and clouds as well as temperature. Climate changes can be caused both by natural forces and by human activities.

However in recent usage, especially in the context of environmental policy, it refers more specifically to changes being studied in the present, including an average rise in surface temperature, or global warming. &quot; class=&quot;glossary-indicator&quot;&gt;i&lt;/a&gt; is becoming clearer and more compelling every day: changes in our climate are real and are under way. Now. But we can do something about it.&lt;/p&gt;

This action is in support of, or opposition to, one side of a controversial argument.

The word &amp;#039;activism&amp;#039; is often synonymous with protest or dissent. It can take a wide range of forms, from writing letters to newspapers or politicians, to rallies and street marches, direct action, or even guerilla tactics.

In contemporary use, &amp;quot;activism&amp;quot; tends to be a word associated with the actions and ideologies of those on the political left. However, activism can stem from any number of political orientations. An activist may be called a freedom fighter by some, and a terrorist by others, depending on which side of the political fence is making the observation.

Activists are people who act as the conscience and voice of many individuals within a society. They address and challenge their nation on ethical and moral, human rights, animal rights, and environmental issues, to name a few.&quot; class=&quot;glossary-indicator&quot;&gt;i&lt;/a&gt;s are exaggerating the certainty in the linkage between human action and climate change&lt;a href=&quot;glossary#term14&quot; title=&quot;global warming: Global warming is a term used to describe an increase over time of the average temperature of Earth&amp;#039;s atmosphere and oceans.

&lt;div class=&quot;quotes-author&quot;&gt;
   &lt;p&gt;&amp;mdash; The Fraser Institute, a &quot;free market&lt;a href=&quot;glossary#term34&quot; title=&quot;market: A market is a mechanism which allows people to trade, normally governed by the theory of supply and demand, so allocating resources through a price mechanism and bid and ask matching so that those willing to pay a price for something meet those willing to sell for it. In some fields of study, a market is assumed to be only this mechanism. However that is an extreme ideological position not shared even by most merchants:

Both general and specialised markets, where only one commodity is traded, exist. Markets work by placing many interested sellers in one place, thus making them easier to find for prospective buyers. An economy which relies primarily on interactions between buyers and sellers to allocate resources is known as a market economy in contrast either to a command economy or to a non-market economy that is based, e.g., on gifts.&quot; class=&quot;glossary-indicator&quot;&gt;i&lt;/a&gt;&lt;a href=&quot;glossary#term27&quot; title=&quot;free market: A free market is an economic term for an idealized market system, where all economic decisions and actions by individuals regarding transfer of money, goods, and services are voluntary, and are therefore devoid of coercion and theft (some definitions of &amp;quot;coercion&amp;quot; are inclusive of &amp;quot;theft&amp;quot;). Colloquially and loosely, a free market economy is an economy where the market is relatively free, as in an economy overseen by a government that practices a laissez-faire, rather than either a mixed or statist economic policy. Within economics the more usual term is simply &amp;quot;the market&amp;quot;, or &amp;quot;the market mechanism&amp;quot;, to mean the allocation of production through supply and demand.

Internationally, free markets are advocated by proponents of economic liberalism. In the United States, support for free market economic structures is a key tenet of U.S. conservatism and libertarianism.

Some believe that the notion of a free market is inherently unachievable because they hold that governments create property rights and are fundamentally involved in markets through the enforcement of such rights. Others argue that the concept of property comes from natural law and therefore it is incorrect to see governments as creating markets.&quot; class=&quot;glossary-indicator&quot;&gt;i&lt;/a&gt;&quot; oriented Canadian think tank.&lt;/p&gt;

   &lt;p&gt;Our carbon emissions&lt;a href=&quot;glossary#term44&quot; title=&quot;emissions: Human activity raises levels of greenhouse gases primarily by emitting carbon dioxide, but other gases, e.g. methane, make a notable contrbution.

The concentrations of several greenhouse gases have increased over time due to human activities, such as:

    * burning of fossil fuels and deforestation leading to higher carbon dioxide concentrations,
    * cattle and paddy rice farming, land use and wetland changes, pipeline losses, and landfill emissions leading to higher methane concentrations,
    * the use of CFCs in refrigeration systems. The use of CFCs and other halons in fire suppression systems and various manufacturing processes.

According to the global warming hypothesis, these emissions of greenhouse gases from industry and agriculture are partly or wholly to blame for recent global warming.&quot; class=&quot;glossary-indicator&quot;&gt;i&lt;/a&gt; will need to be cut by 10% each and every year for a 25-year period to bring convergence between rich and poor nations&lt;/p&gt;
