Global Warming Causing Frequent Heat Waves



Summer is just around the corner and one can easily notice that days are now warmer and more humid than last year’s. It is quite impossible nowadays to spend the whole day out at the beach—with or without sunblock!

Climate experts even predicted that hot and humid days will occur frequently and a lot longer this year and, unfortunately for the years to come which will result to life-threatening heat waves. Heat waves are known to earn fatalities over the countries it hit in the past. Aside from that, heat waves put children under 4 years of age and older people 65 years above in a greater health risk—usually fatal.

Natural and Human Threats to the Amazon’s Ecological Treasure



Rapid rise in global warming is expected to get worse as the world’s most important natural land sink for carbon dioxide – the Amazon rainforest – is facing threat from both natural and anthropogenic causes. On the one hand, the forest is being affected by drought while another threat to its ecological treasure lies ahead in the form of the human quest for fossil fuels.

Continual research on the Amazon rainforest, recently recapitulated in an international study led by Professor Oliver Phillips of the University of Leeds, has found an alarming rate of increase in the incidence of ‘tree deaths’ due to drought. According to the research, involving more than the 60 scientists from over 40 institutions in 13 countries, the CO2-absorbing capacity of the forest is steadily declining as drought is causing the death of more trees each year. This is particularly the case with Amazon’s palm trees, which are highly sensitive to dry climate.

What is Deforestation



Deforestation is something that “we” humans are responsible for, it is the logging of trees in forested areas. Each day, trees are sold as a product are used, cleared used for grazing land by humans. Deforestation is largely unknown and there are no consequences amongst the people damaging the planet in this matter.

It has been known that forests disappear naturally by extensive climate change, fires, hurricanes or any other disturbances that are not caused by people. However, even when these horrible events occur, we never prevent them, nor do we help change what has been done. This topic has been the key focus for scientist to debate; it is a rising issue, which needs to be looked at more.

What is the Carbon Cycle?



To most scientists it is considered one of the most important things to be acquainted with during these chaotic times. This interesting factor is the biochemical cycle in which carbon is exchanged among the hydrosphere, pedosphere, geosphere, biosphere, and atmosphere of our planet Earth. The Carbon Cycle is primarily thought of as four major reservoirs, in which carbon interconnects by varies pathways of numerous exchanges.

The four major reservoirs are:
–The atmosphere.
–The global biosphere. Which is defined to include the fresh water systems and non-living organic material, such as soil carbon.
–Our Oceans, as well as dissolved inorganic carbon and living and inert marine biota.
–Finally, the sediments, which is also including fossil fuels.
For example, take the atmosphere. Carbon exists in the Earth’s atmosphere mainly as the gas ‘carbon dioxide’; although it’s only a small percentage of the atmosphere. Yet, it plays an important role in supporting life.

The effects of global warming on Polar Bears



The change in our planet’s temperature has had a drastic effect on all living creatures.  The polar bear, native to the North Pole is one such creature.  Global warming has not only threatened its natural environment but has also affected its feeding ground, reproductive capabilities and territory.

Experts say that there are around 20,000 polar bears out in the wild.  But these numbers could decline by as much as 35% in the next 30 to 50 years.  This decrease is largely due to the disappearing ice in the North Pole.
