A discussion on the issues of global climate change and environmental degradation

Climate change effects have been linked to the rise [] and also the collapse of various civilizations. The models may be used to predict a range of variables such as local air movement, temperature, clouds, and other atmospheric properties; ocean temperature, salt contentand circulation ; ice cover on land and sea; the transfer of heat and moisture from soil and vegetation to the atmosphere; and chemical and biological processes, among others.

Climate models have been used to examine the role of the Sun in recent climate change. This section explores some of those fears to see if they are justified or not. One climate commitment study concluded that if greenhouse gases were stabilized at year levels, surface temperatures would still increase by about 0.

This can affect both global and local patterns of climate and atmosphere-ocean circulation. It has also attempted to put a value on the ecological services provided to humanity. This notion of climate justice is typically ignored by many rich nations and their mainstream media, making it easy to blame China, India and other developing countries for failures in climate change mitigation negotiations.

Historical impacts of climate change Climate change in the recent past may be detected by corresponding changes in settlement and agricultural patterns.

Loss of Biodiversity and Extinctions

The rest of this increase is caused mostly by changes in land-use, particularly deforestation. Because of poverty, age, health, and location, the poor are especially susceptible to the potential negative impacts of global climate change. Cloud and Precipitation Past precipitation can be estimated in the modern era with the global network of precipitation gauges.

Some of this surface warming would be driven by past natural forcings which have not yet reached equilibrium in the climate system. Some studies point toward solar radiation increases from cyclical sunspot activity affecting global warming, and climate may be influenced by the sum of all effects solar variation, anthropogenic radiative forcingsetc.

Geological Survey projects that two-thirds of polar bears will disappear by Despite an increase in conservation efforts, the state of biodiversity continues to decline, according to most indicators, largely because the pressures on biodiversity continue to increase.

The rest has melted ice and warmed the continents and the atmosphere. A world glacier inventory has been compiled since the s, initially based mainly on aerial photographs and maps but now relying more on satellites. Some changes in climate may result in increased precipitation and warmth, resulting in improved plant growth and the subsequent sequestration of airborne CO2.

They include the following diverse effects: According to professor Brian Hoskinsthis is likely the first time CO2 levels have been this high for about 4.

It covers millions of square kilometers in the polar regions, varying with the seasons. More recently, altimeter measurements—in combination with accurately determined satellite orbits—have provided an improved measurement of global sea level change. The Great Oxygenation Event —oxygenation of the atmosphere around 2.

Back to top Long Term Costs If ecosystems deteriorates to an unsustainable level, then the problems resulting can be very expensive, economically, to reverse. In terrestrial ecosystemsthe earlier timing of spring events, as well as poleward and upward shifts in plant and animal ranges, have been linked with high confidence to recent warming.

As the bishops said in their June statement, Global Climate Change: Global warming refers to global averages. The study of these ice cores has been a significant indicator of the changes in CO2 over many millennia, and continues to provide valuable information about the differences between ancient and modern atmospheric conditions.

The atmosphere would suffer from more pollution. The World Glacier Monitoring Service collects data annually on glacier retreat and glacier mass balance. Will all this mean a different type of spin and propaganda with attempts at green washing and misleading information becoming the norm, or will there now be major shift in attitudes to see concrete solutions being proposed and implemented?

Over the last three decades of the twentieth century, gross domestic product per capita and population growth were the main drivers of increases in greenhouse gas emissions. A delegation of globally diverse grassroots leaders will be in attendance at the NY march to ensure voices from movements and campaigns around the world are heard.

The first stumbling block, however, has been trying to get an agreement on a framework. They will also emphasise various ongoing struggles which will carry forwards beyond September. We are excited to introduce to you this group of global climate ambassadors!

For earlier periods, most of the evidence is indirect—climatic changes are inferred from changes in proxiesindicators that reflect climate, such as vegetationice cores[6] dendrochronologysea level changeand glacial geology.

This section looks at this Convention and some of the main principles in it. Glaciers leave behind moraines that contain a wealth of material—including organic matter, quartz, and potassium that may be dated—recording the periods in which a glacier advanced and retreated.

Flexibility mechanisms were defined in the Kyoto Protocol as different ways to achieve emissions reduction as part of the effort to address climate change issues. Variations in CO2temperature and dust from the Vostok ice core over the lastyears Human influences Main article:Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years).

Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions. Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.

Multiple lines of scientific evidence show that the climate system is warming. Many of the observed changes since the s are unprecedented in the instrumental temperature record, and in paleoclimate proxy records of climate.

The environmental issues part of global issues web site looks at issues such as biodiversity, climate change and global warming, genetically engineered or modified food, human population, animal and nature conservation and natural disasters.

At its core, global climate change is not about economic theory or political platforms, nor about partisan advantage or interest group pressures.
