Dear Saxena

Many studies predicts warmer global climate through 2100, and the amount of extreme heat will depends on the amount of fossil fuels will be burn.

Melting of permafrost and release of methane. This greenhouse gas will accelerate the process. Also, release of microorganism, which were in anabiosis in permafrost.

Dear All,

Thanks for your answers.

Global warming on life on earth in the next 100 years will change human life and human distribution.

Hi,

Global warming does melt glaciers due to the overall rise in temperature. Furthermore, the temperature rise will result in the extinction of many species. In short, it would cause a hindrance to all biological mechanisms.

Thanks for your answer.

Hi,

Global warming - an advertising subject, which is not well defined (which parameters argue on absolute values about this process occurs: on temperature, gas, melting.. not well defined yet) so, this is under disscusion.

To say about 100 ys dynamics of our system is difficult, even difficult for 50 ys.

For me is necessary more data.

Sandu

It appears to me that it is absolutely impossible to forecast the consequences of global warming in next 100 years.

Thanks for your answer.

Dear Thierry de Mees,

Thanks for your answer.

I endorse the views of Dr. Thierry.

Extensive utilisation of fossil fuels have certainly contributed to Global Warming, which is still extending on higher side, it is a fact the learned community already know and discussed very well. However, as Dr. Sandu said, its difficult to carry out 100 Year predictions, for which certainly You need to have more data. Moreover, research is a must as it gives you past, present and future trends. Nevertheless, the last one is important - the future. For which, certainly it is needed to have much more data sets to consult, refer and interpret.

Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.

Even if the atmospheric composition of greenhouse gases and other forcing agents was kept constant at levels from the year 2000, global warming would reach about 1.5℃ by the end of the century. Without changing our behaviour it could increase to 3-5℃ by the end of the century.

Presently, according to statistics the atmospheric heat is altering and eliminating habitat, reducing food sources and causing drought.

Then in 100 years to come, the condition will be more severe.

Except under the most aggressive mitigation scenario studied, global average temperature is expected to warm at least twice as much in the next 100 years as it has during the last 100 years. Ground-level air temperatures are expected to continue to warm more rapidly over land than oceans.

The extinction of live beings is one of the natural laws. During long millennia, the earth has seen numberless major upheavals (telluric accidents, glaciation, warming, meteorites, earthquakes, gigantesque volcanic phenomena...) all accompanied by live beings' extinctions and other live beings' apparitions. Gaia has survived all these cataclysms; living beings adapted themselves or disappear long before the apparition of Human beings. This is a natural law.

Adaptation and resilience to climate change: Is it absurd to assume, like for the evolution of species and their adaptations to natural changes of all kinds, that adaptations and resilience to the effects of climate change should readjust themselves, to changes in natural conditions, which by definition are very slow and loaded with uncertainties?

Moral: what are the urgent actions for scientists, decision-makers, actors, and active civil societies, and on what issues should scientific, technical, and financial resources should be concentrated? At what time scale should we consider the priority measures to be implemented in order to ensure the protection of natural resources and guarantee their sustainability? (i) direct and urgent measures associated with the modes of exploitation and development of resources ; (ii) indirect and very long-term implications of Climate Change on the potential of resources. Has everything been done on (i) to decree that it is urgent to tackle (ii) head-on with all its uncertainties, particularly with regard to time scales involved, incompatible with the scales of concrete actions?

Water-scarce countries should shift toward an integral and integrated vision of all water resources: First, integration of water in all its states: surface water, groundwater, treated water, green water (water resource of the soil available for crops), virtual water (water equivalent of agrifood trade)..., then integration of water in all its uses: agricultural, domestic, industrial, tourist, environmental, recreational..., finally integration of water in all its actors: State, administration, communities, technicians, scientists, users, consumers, citizens. Beyond the improvement of management methods, this strategy must achieve a change in our behavior with regard to the very notion of water resources.
