Climate

Climate Change is the main issue of the 21st century. Yes, the Earth’s climate has always fluctuated from hot to cold, but at the same time as rapid climatic change, we see devastating punctuation in the fossil record of life on Earth. Mass extinctions caused by disparity between ecosystems and the weather that sustains them. So why do we continue to use fossil fuels when there is a clear link between emissions of greenhouse gasses, predominantly CO2from fossilised energy resources?

A bit of a political propaganda vid, but it contains some interesting images and information on the European Emissions Trading Scheme. 

Everyone controls climate change: YouTube video from the European Union

This short and simple cartoon video is aimed at making children more energy conscious, showing people turning into super-hero type characters when the turn off lights and other electrical appliances. 

Living With Climate Change YouTube video from the European Union

This video clearly illustrates that anthropogenic climate change is happening. It also shows stories by people who are directly affected by the negative economic impacts of climate change and why it is important to reduce our dependance on fossil fuels.

Act on CO2 YouTube video from the UK's Department for Environment, Food and Rural Affairs (Defra)

The Department for Environment, Food and Rural Affairs (Defra) is the UK’s government department responsible for environmental protection, food production standards, agriculture, fisheries and rural affairs.


Defra's principal aim is sustainable development, which is defined as "development which enables all people throughout the world to satisfy their basic needs and enjoy a better quality of life without compromising the quality of life of future generations."


Defra has five strategic priorities:


  1.  Climate change and energy.

  2.  Sustainable consumption and production.

  3.  Protecting the countryside and natural resource protection.

  4.  Sustainable rural communities.

  5.  Sustainable farming and food sector including animal health and welfare

Creating a Low Carbon Economy YouTube video

This video starts by showing first hand some of the important reasons for combating anthropogenic climate change, such as droughts, floods and heat-waves. It moves on to concrete targets for CO2 (carbon dioxide) emissions for EU (European Union) member states through new climate and energy policy through stimulating growth in a new, low carbon economy.

20% Renewable by 2020

This YouTube video describes the EU's targets to produce 20% of its energy from renewable resources by 2020. This of course is to reduce CO2 emissions by a similar proportion in order to combat potentially devastating anthropogenic climate change.

Ground source heat pumps explained

Ground source heat pumps use 25%–50% less electricity than conventional electric heating or cooling systems, because they extract low temperature heat from below ground level, from a large liquid filled pipe system installed approximately 1m deep. They use a electo-mechanical system similar to those used by a fridge or freezer to convert the low temperature heat from the ground into usable heat for your home or office. 

A ground source system runs at a lower temperature than conventional heating systems, for this reason oversized radiators or underfloor heating should be used. This allows sufficient surface area for the transfer of heat(rate of heat transfer is governed by the temperature differential between the hot and the cold objects, resistance to heat flow - such as insulation, and the surface area through which the heat is transmitted). 

As with other types of energy saving technology, upfront costs are often seen as a disincentive, but there are now excellent interest-free loans and Government grants available towards the cost of equipment and installation due to the energy and greenhouse gas emissions saving benefits of these systems. 


Ground source heat pumps reduce energy consumption and corresponding greenhouse gas emissions by up to 44% compared to air-source heat pumps and up to 72% compared to electric resistance heating.

Climate data explained

The figure above gives us a brief overview of the past 450,000 years of temperature, atmospheric dust and  CO2 (carbon dioxide) data. The data is gathered from analysis of bubbles in ice cores, oxygen isotope ratios of materials in the  stratigraphic record, coupled with other modern geological techniques. For further information on geological aging techniques follow the links below.


                            geological analytical techniques:


                            stratigraphy

                            carbon dating

                            Strontium : Rubidium isotope analysis

                            oxygen isotope ratios

                             ice core analysis


While the temperature of Earth’s climate has fluctuated naturally due to the release of COfrom the Earth’s crust during volcanic eruptions and other forms of venting associated with flood basalts, these changes from cool to hot phases have always been associated with massive reductions in biological diversity, and biomass, on a global scale (see here for more details). The intensity of this biological loss is strongly correlated with the rate and amplitude of the climatic change.


The consensus of the scientific data available today is irrefutable. We are releasing CO2 into the atmosphere at an unsustainable rate. The reason is that these fossil resources were formed over hundreds of millions of years, and yet the release of their stored gasses is taking us only a few decades. 


In returning these lithospheric deposits (stored in the ground) of carbon  to the atmosphere, we are reverting the climate to a composition that has not existed on this planet for over 500,000 years. We are also doing this at a rate unprecedented in history, with unforeseen consequences, on a global scale, of a magnitude beyond human conception. 


It is never too late to act upon these problems, but delaying doing so will undoubtedly raise the final bill. The solution is as simple as reversing the processes by which we have altered the Earth’s systems from their natural state. We must do this by developing environmentally positive, cyclic human systems that provide the resources to society, without compromising prosperity in the future, nor that of any of our fellow organisms, upon which our combined futures may depend.
