China's yearly precipitation trends namely no obvious

Global warming Global warming refers to the period of period, the Earth's atmosphere and the phenomenon of rising ocean temperatures, mainly refers to the temperature heave caused along human elements. The cause is probably due to greenhouse gas emissions caused by excessive.
universal warming is a radiation, apparent light has a high degree of permeability, meantime the long-wave radiation reflected from the earth is extremely absorbent, it is often said that the to protect the Earth's climate system, will be greatly compressed
alive space where people are weather conditions when the temperature is higher than usual,it says, some people will think that the climate warming; while some places have become extremely cold, this is climate change Warm it? warming the earth in the end is not in it, what factors come into melodrama?
held recently in Beijing, Dr. Zhang Chengyi from greenhouse gas (GHG), temperature, precipitation patterns and the impact on the ecosystem, etc., to show us the technological evidence on climate change.
carbon dioxide thickens, Zhang said humans at mistake
means that the atmospheric greenhouse gas concentrations and total amount are on the rise.
in the Antarctic, due to low temperature, sleet can not melt. snowfall collection will persist to restrain some of them air bubbles. Scientists drilling ice cores at differ depths specimen, extract the air bubbles, to diagnose the gas essay and the isotopic dating, the earth can be won in a kind of different historical times and atmospheric makeup change message. based on ice core data are obtainable, and immediately the Earth's atmosphere of carbon dioxide, methane and nitrogen oxides and other greenhouse gas concentrations are the highest since the past 80 years.
Although modern cloudy carbon dioxide concentration is the maximum in almost 80 years, but its the same bit merit is not high. but can be deduced: the modern high concentrations of gaseous carbon dioxide generated chiefly from the age-old carbon. which is chapter of the combustion of carbon is buried in the floor from the generation of person age-old fossil oils. So high levels of carbon dioxide in the atmosphere than natural processes, but human emissions . research further accustomed that: the concentration of atmospheric carbon dioxide in the quondam 150 years and rising carbon emissions from human use of fossil fuels with the accord of the bend.
direct decision of the atmospheric results show that: It is now the Earth's surface concentrations of atmospheric carbon dioxide has been surpassed 380ppm (ie one million copies of the volume contains 380 carbon dioxide), the rising concentration of atmospheric greenhouse gases, will surely improve its greenhouse achieve, to make warming. temperature increases, chronic on the Earth's surface air temperature
Direct instrumental analysis of data showed that: the past century from 1906 to 2005, global average surface temperature rise is 0.074 degrees Celsius per decade, from 1956 to 2005 5 years per ten-year warming trend of 0.128 degrees Celsius , close to the warming trbring an end to ... recent years to 2 times, from 1981 to 2005 twenty-five years per decade warming trend of 0.177 degrees Celsius, the warming trend for the past hundred years 2.4 times, showing a warming trend over time accelerating the momentum for.
lesson, there may also be superimposed on natural variability, there are some uncertainties.
warming will be further amplified in the future. IPCC Fourth Assessment Report that: to the end of the centenary Global average surface temperature will rise the maximum probable scope is 1.1m6.4 degrees Celsius, but still may be beyond or underneath this range. Even the maximum conservative estimate, is now to stop human emissions of greenhouse gases such as carbon dioxide, the greenhouse in the atmosphere from the new high gas concentrations can not be immediately dropped to the class before the industrial revolution, the Earth's temperature would still rise and rise of the most likely value is 0.8 degrees Celsius.
precipitation conditions, averaging extra wrong
Zhang said that the the globe has changed precipitation patterns, rainfall conditions chance needy, the contingency of massive rains and floods increased taint erosion was intensified state of affairs, the availability of precipitation falling.
nearly 100 years, China's daily precipitation trends is not obvious, but showed premonitory interannual and interdecadal oscillation. in the final century's and 80m90 30m40 upon regular rainfall years, other years rainfall. China's daily precipitation there is a clear regional inconsistencies, in recent 50 Years in China's northwardly, northeast and east and south, northwest and Asian regions of the annual precipitation there is a remove decline in the Yangtze River, Huaihe zone, South China and Northwest China there are more manifest in most of the increase in precipitation.
In fact, the Earth's ecosystems, category The relationship between very subtle, is varied. Because changes in the statute of biological development, it is likely to set up long-term mutation of the relationship between the category change, so that some category facing calamity. Britain, a learn suggests Great tits are migratory birds, spring migration to the UK every annual for propagating, edible is the UK rely aboard the local fruits of the spring flowering and fruiting plants. As the climate warming in recent years, while it arrived in Britain migration,toronto escort, those factories long flowering and fruiting, fruit intake for greatly dwindled, reasoning the bird's population dripped dramatically in recent years. Therefore, under the inspire of climate change, species change alternatively accustom to climate change, the relationship with additional species, or face the risk of extinction. IPCC Fourth Assessment Report in that, when the temperature is further additional 1m3 degrees Celsius, about 30% of species face extinction risk.
biological communities and ecosystems are also due to the geographical distribution climate warming and precipitation changes and their synergies to change. Zhangguangcai South China Heilongjiang Laotudingzi incline, m on the northern tilt of the mountain birch tundra conversion region, Mountain alpine area, have scrutinized the Ministry of woods trees in the online update boost in baby age, density of trees, tree species to climate warming for the overall upward trbring an end to ... migration.
of climate change on ecosystems will also exert a straight influence to change its framework and services. Finally, Zhang said the Italian said that the impact of climate change are many, some changes may have occurred earlier, while others may be later. But the human need to pay near attention to climate change, to take forcible amounts to adapt to and alleviate climate change, while dodging disadvantages, protect the Earth's climate system, the harmony between male and nature.

merely 26% of the young human concerned approximately air change
just ended in mid-May by the Cultural and Education Section British Embassy and the Science and Technology Daily The survey total of over 22,000 young professionals through networking, interviews and dispute groups in the form of participation, of which 97% of the respondents were students or serving commanders, 92% of the undergraduate pedagogy degree.
for this result, National Climate Center China Meteorological Administration, visitor speck, capital scientist Dr. Zhang Chengyi said: After reading the results of this survey namely a representative. but we kas long asclimate is no namely every of us lives a absence of resources, we can not depart the temperature to life, and this temperature is the nature invested free of charge to our climate. We kas long asin this process, the atmosphere contains greenhouse gases, the greenhouse gas to keep the Earth by an mean of negate 15 degrees Celsius, without the greenhouse gases, our survival space ambition be ziped greatly, not even. atmosphere stream, moisture evaporation from the oceans, we can not live without water, this is someone very important.
Therefore, we must foster environmental awareness, to disburse care to the real life environment, focus on our atmosphere,beijing massage, care to have a major clash on our lives of resources, I think this is the need to make efforts and cultivate an appearance.
