with all this global warming gubbins going on in 10-20 years time how is this going to affect our fishing is it for the better or for the worse?
im nto sure what exactly is going to happen if anything even does im not sure but was thinking about it and thought this could change our fishing in this country but not sure how?

Global warming is a government scare tactic,
Over millions of years the earth changes and evolves, climates have altered drastically over this time, no-one ever blamed the dinosaurs for rising or lowering temeratures did they? All this bull about co2 emissions is another way to extract money from people and companys, carbon emissions is the new buzz word that the people up high are using to brainwash us into thinking these massive car tax hikes etc.. are all for a reason.

Yours maybe mate my name is Stig Mcleod from the clan McLeod and i have partied like it was 1699 ,1799 ,1899 and 1999 looking forward to 2099 and 2199 . As long as i dont lose my head in the mean time ![]() ![]() ![]() No in all seriousness the last time the heat was on like it is supposedly going to rise to, we went from heat on to iceage in a matter of 10 years ! With that fact in mind you may not be here to see most of the world under water but you could well be here to see most of Britain under huge glaciers ![]()

Lad's......It's simple really,
Most plants are photoautotrophs, which means that they are able to synthesize food directly from inorganic compounds using light energy - for example from the sun, instead of eating other organisms or relying on nutrients derived from them. This is distinct from chemoautotrophs that do not depend on light energy, but use energy from inorganic compounds. 6 CO2 + 12 H2O → C6H12O6 + 6 O2 + 6 H2O The energy for photosynthesis ultimately comes from absorbed photons and involves a reducing agent, which is water in the case of plants, releasing oxygen as a waste product. The light energy is converted to chemical energy (known as light-dependent reactions), in the form of ATP and NADPH, which are used for synthetic reactions in photoautotrophs. The overall equation for the light-dependent reactions under the conditions of non-cyclic electron flow in green plants is: 2 H2O + 2 NADP+ + 2 ADP + 2 Pi + light → 2 NADPH + 2 H+ + 2 ATP + O2 [3] Most notably, plants use the chemical energy to fix carbon dioxide into carbohydrates and other organic compounds through light-independent reactions. The overall equation for carbon fixation (sometimes referred to as carbon reduction) in green plants is: 3 CO2 + 9 ATP + 6 NADPH + 6 H+ → C3H6O3-phosphate + 9 ADP + 8 Pi + 6 NADP+ + 3 H2O [3] More specifically, carbon fixation produces an intermediate product, which is then converted to the final carbohydrate products. The carbon skeletons produced by photosynthesis are then variously used to form other organic compounds, such as the building material cellulose, as precursors for lipid and amino acid biosynthesis or as a fuel in cellular respiration. The latter not only occurs in plants, but also in animals when the energy from plants get passed through a food chain. Organisms dependent on photosynthetic and chemosynthetic organisms are called heterotrophs. In general outline, cellular respiration is the opposite of photosynthesis: glucose and other compounds are oxidised to produce carbon dioxide, water, and chemical energy. However, both processes take place through a different sequence of chemical reactions and in different cellular compartments. Plants absorb light primarily using the pigment chlorophyll, which is the reason that most plants have a green color. The function of chlorophyll is often supported by other accessory pigments such as carotenes and xanthophylls. Both chlorophyll and accessory pigments are contained in organelles (compartments within the cell) called Chloroplasts. Although all cells in the green parts of a plant have chloroplasts, most of the energy is captured in the leaves. The cells in the interior tissues of a leaf, called the mesophyll, can contain between 450,000 and 800,000 chloroplasts for every square millimeter of leaf. The surface of the leaf is uniformly coated with a water-resistant waxy cuticle that protects the leaf from excessive evaporation of water and decreases the absorption of ultraviolet or blue light to reduce heating. The transparent epidermis layer allows light to pass through to the palisade mesophyll cells where most of the photosynthesis takes place. Plants use up to 90% of the light that strikes them, whereas commercial solar panels use less than 30%. This is achieved by groups of chlorophyll molecules spending a long time in a superposition of states. and thats all there is to it. SB.
