Temperature and survival

Imatge
Every specie is linked with the climate that it was born. Food, water or oxygen quantity determines size, shape and age to dead. When some boundary change being must change or disappear. Imagine if in the world all our possible meal disappears and other possibilities of eat will become a poison. Yes, it’s an extreme situation which is impossible to happen in our current boundary conditions but not of all impossible with other planetary boundaries that was happened in other geological times. Fish survive is in threat as ours We can’t survive in Cretaceous Age , not for the existence of terrible dinosaurs but we can’t breathe the air with our current lungs; we would walk in Cretaceous Age as we are in Pandora’s Moon of the Avatar film . As us in Cretaceous, the Jurassic animals couldn’t survive in our time (even if will resucite them as Jurassic Park ). The current air is an advantage, something that we can see with their direct sons: the birds which able to fly only with ...

Spring in February

Imatge
Everyone knows that spring comes on March 20, so today spring starts to coincide with astronomical equinox. However equinoxes precession ahead due to global Earth's axis (which some have spoken again, " Why change hour twice a year? ") At a rate of a little more one day per century; if don’t make a reform as the Gregory XIII in sixteenth century , sooner or later equinox and the beginning of spring will happen in the middle of February. Anomalia Frebruary 2016 But astronomical considerations aside, I would want to talk about is atypical month of February we have been in the northern hemisphere. Unlike other years, the austral summer is not being used as much drive. Instead the southern winter literally no happened. It is true there have been some storms, snow, cold snaps ... but usually the months of January and February were weak between autumn and early spring. In recent years the southern winter had been shortened in number of days, literally this year in m...

Climate hits us

Imatge
Explain a tale that two rabbit saw a group of animals came running towards them. When seeing them, instead of putting on a prudent defense, they started a discussion on whether greyhounds were coming hunt both or a few pigs who gave them a ride. While they were discussing whether something or other, the pack of dogs reached a distance where they could not distinguish if they were, but it's too late to flee. Today regarding climate change will still discussing whether or not when already noticed this breath. Extreme weather devastation Where are the deniers of climate change? Even a year ago at the height snowstorm in the Northeast US, a congressman of science committee had the nerve to show a snowball and questioning the science on global warming; Today the Northeastern US which has almost summer temperatures, we should ask him where are his hidden snowball. At Christmas 2013 and 2014 entry a sudden cold wave in the summer of Antarctica caused hilarity of the skepti...

More than words we need to solve Climate Change

Imatge
A week from the Paris summit on Climate Change , the umpteenth summit short, it seems that already have a firm commitment. Despite rumors so that to achieve a global commitment has begun to thin, and certainly this end the umpteenth summit bankruptcy. The point is that we have the G20 and the EU to form the block of developed countries, these are countries that issue, as well as due to economic globalization oblige countries to be also highly polluting. And on the other side we have the capital world of the need to produce as much energy to transport, has opted for the safest source of energy are: fossil fuels. As I explained in " Why the oil and coal consumption increase every day? " Everyone is embarked on this energy, now leave it would cause many losses. Extreme weather growth We passed many years of climate conferences and summits with big headlines, statements, commitments and timetables which we never fulfilled. One reason for this was the lack of awarenes...

In 30 years it has increased the pace of accumulation of CO2 in the atmosphere

Imatge
A UN report shows that the rate of accumulation of CO 2 and other gases is increasing year after year It will soon be 17 years from the signing of the Kyoto Protocol that drove reducing emissions of greenhouse gases. Part of the protocol referred to CFC s already being eradicated because of another also deleterious effect on the atmosphere was fulfilled: the destruction of the ozone layer; but the most important reducing CO 2 emissions from the combustion of hydrocarbon energy to achieve, not only it hasn’t been met but that emissions have increased. A report commissioned by the United Nations Intergovernmental Panel on Climate Change (IPCC) shows that in the last 30 years CO 2 is still accumulating in the atmosphere, it also shows an acceleration almost double the rate of accumulation was in the 80s . The consequence is clear the average temperatures increases, due to the greenhouse effect, the effect caused by CO 2 and other gases, decreases the amount of heat rele...

The fossil CO2 is going out Permafrost

Imatge
In July of 2014 irrupts the amazing news of the discovery in Permafrost one huge crater of about 80 meters in diameter in a remote part of Siberi, specifically in Yamal Peninsula. The needed of the time to arrive until this far region, created a mount of urban tales that what could it be. From first images we can observe the considerable. The news had spread like wildfire because of the legend of " Well to Hell " (Well where we could go down to hell) that is supposed to Siberia , although this urban legend is the result of the craters produced by opencast Russian that can be seen from satellite. Several hypotheses have been considered. First they think about the possibility of a meteorite, probably induced by the psychosis that produced the massive drop in a year, but can rule out the tubular shape of it. Today we know taht is a gas explosion, logical that area is the largest number of farms and gas resources of Russia, and also in very small scale found in the Permafrost A...

Coal, a drug for mankind very difficult to leave

Imatge
Published in Linkedin: Coal, a drug for mankind very difficult to leave (28/11/2014) If someone asks for jobs with less future, probably in all lists would write the coal mining . Coal has historically generated many jobs, however mechanization has been declining number of employers; but in many parts of the developing world is still mining, sometimes in border on slavery, which is feeding (bad eating to be exact) many people from earliest childhood. Now a danger is hovering over this form of living. Although coal will remain nearly 300-year to explode with current consumption, but the need to reduce CO 2 emissions questions the continuity of this mining. Coal was the engine of the Industrial Revolution . The steam machines from the eighteenth and nineteenth centuries moved thanks to black stones that we could burn. But the twentieth century discovered a new fuel: the Oil , which was more manageable, easy to get and it has more potential uses. Later he appeared a third co...

The carbon bubble

Imatge
Atmospheric CO 2 is arriving other time at 400 ppm . Obviously last moths it was under mythic threshold but to follow the sawtooth graphic seems that the problem was overcome, but on the contrary graphic trend is growing in exponential. However as I related in “ Are 400 ppm of CO 2 the border to beginning the Armageddon, or not? ” to pass the threshold doesn’t mean that climate begins a spiral of weather disasters. Deniers, in their crusade against the evidence in climate , have profit of a cool winter for beginning their ridiculous idea of Global Cooling . Global Cooling is possible but to put tones of CO 2 in atmosphere isn’t a solution because Earth will be heating until CO 2 and temperature will take other time the equilibrium; but in other hand high CO 2 could do a rebound effect which will carry climate to the Ice Age (read “ The day after Tomorrow ”) CO 2 is growing and nobody does anything. The more powerful oil industry moves all of its influences for to stop ...

We must change the way we see energy

Imatge
What does it mean Renewals Energies ? Strictly nothing, energy is used and never comeback. When we refer to term renewal, this term design a kind of energy which has sources that are regenerate in natural form. It can be a good definition for more people and very similar of majority of definitions in internet, but Oil , for example, can entry in this definition: today Earth continues making oil; in other side Geothermal Energy that is including in renewals category, in fact it doesn’t: geothermal is due to the potential energy of all Earth material had before formation which warmed interior of planet when joint then, volcanoes and earthquakes are cooling slowly the earth because there aren’t any energy input, except of nuclear and gravitational tidal both of very inferior order. So what is due that we believe the reverse of what they are? Essentially because oil consumption is much higher than the capacity of its formation, so much that we can consider today Earth don’t make; and...

Are 400 ppm of CO2 the border to beginning the Armageddon, or not?

Imatge
At last we arrived at 400 ppm of CO 2 in the atmosphere .  Two decades of conferences, commitments and challenges don’t stop the growth of CO 2 atmospheric concentration. But we aren’t listening celestial trumpets or seeing angels armed with fire-swords down from heaven. It’s true, the predicted Apocalypse doesn’t start yet, but the barrier of two times the concentration of CO 2 of pre-industrial age is significant not to be a round number bur it had never exceeded in the last 600,000 years . However importance is that in first we are entering in ‘ terra incognita ’ with respect to fossil records, and second ours mathematic climatic models are out too of confidence interval; and now anything unforeseen or expected can happen. What does it mean Terra Incognita? As I explained in: Really are temperatures stopping its rice , climate models are a set of nonlinear differential equations and as such are very conditioned to the boundary conditions; this determines the calculation ...

Hot today doesn’t necessary mean Cretaceous Climate tomorrow

We are now in one of the hotter summer until we have data, and affect all north hemisphere. The extreme climatic episodes has augmented in last years and it’s a prove the begin of climate change.  The most relevant effect is the growing of mean planetary temperature associate at the growing of CO 2 concentration. Both grows are simultaneous and the most preoccupant of them is that is making with exponential form. But can we affirm that the future weather will be the same of the Cretaceous age in a few years? The answer is not trivial. The growing of greenhouse gasses help to grow the atmosphere temperature, and the growing of temperature augment the concentration of this gasses, this fact is naming Feedback. Feedback is the main mechanism to guide the atmospheric processes. There are same studies that show the correlation of CO 2 concentration and temperature, and there are numeric models that demonstrate this correlation. This thing don’t mean that we had burned a lot of fossil...

The drop that makes a glass overflows

If you fill a glass until the top and the last section we do drop to drop, we reach a point where a drop enters the glass begins to overflow. We can consider that the penultimate drop completed volume of the glass and last drop did not fit and so it fell by the side. So just get out there would expect a drop, but in reality much more water overflows. This behavior is caused by the surface tension of the liquid that links the surface preventing it from breaking, thus the last drops before overflow don't fit but tension doesn't let water to fall by side. When it starts to overflow? So when the weight of the liquid is higher than the tension, the surface loses its mechanical consistency and breaks, it let out all the excess liquid. There are other metastable situations that after passing the threshold of stability, under certain conditions so close to threshold, it remains stable until they were disturbed or too move away to threshold. The instantaneous vaporization of water’s gl...
