The concept of climate change has been around for quite a while. The earliest mention of climate change dates back to the 19th century. Swedish scientist, Svante Archenius was the first scientist to study the effect of CO2 on climate. (Rodhe et al 1997)
The Intergovernmental Panel on Climate Change (IPCC) defines climate change as “A change in the state of the climate that can be identified (e.g by using statistical tests) by changes in mean and/or the variability of its properties and that persists for an extended period, typically, decades or longer. Climate change may be due to natural internal processes or external forcings, or anthropogenic changes in the composition of the atmosphere or in the landuse”
The UNFCC also defines climate change as “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over time periods.”
Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide, Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere make the earth habitable with respect to regulating the earth’s temperature. However, an increase in the concentration of these gases results in trapping energy in the atmosphere and this in turn increases earth’s temperature. “Global greenhouse gas emissions have grown since pre-industrial times, with an increase of 70% between
Climate change is a change in the average global or regional weather patterns. Climate changes includes factors such as; temperature, precipitation, humidity, wind and seasons, influenced by oceans, land surfaces and ice sheets. This plays a
According to The Framework Convention on Climate Change, “[climate change is] a change of climate that is attributed directly or indirectly to human activity that alters the composition of the global atmosphere, and that is in addition to natural climate variability over comparable time periods” (Pielke 31). Many climate change deniers like to focus on the latter portion of this definition, claiming that the warming changes currently being experienced throughout earth’s climate are a naturally occurring phenomenon, and that the earth goes through periods of
Climate change is defined as the change in global or regional climate patterns, which is apparent from the mid to late 20th century onwards. When looking at climate change there is an abundance of evidence that supports that humans are the leading causes of the drastic shift in the weather pattern but there is also a lot of evidence against humans actually causing climate changes. For example, the increasing levels of man made gases that are let into the atmosphere may have created a greenhouse effect, which traps heat and ultimately causes global warming. But there are also many scientists who believe that the earth has always naturally cooled down or warmed up at its own pace.
Scientists refer to global climate change as any alteration in the average temperature involving the climate system. The climate system involves the following: our atmosphere, including temperature, clouds and wind, precipitation, humidity, atmosphere trace gas and aerosol distribution; oceans; volcanoes; land; cryosphere, which includes ice cover and snow cover; and the sun (Murck, Skinner, & Mackenzie, 2010). The alternations have been
a long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature. “http://www.dictionary.com/browse/climate-change”
Climate change is the altering of ordinary weather patterns around the globe because of excessive greenhouse gas emissions, particularly carbon dioxide
Climate change is the change in average weather of a region. Climate change can be, for example, change in region’s average annual rainfall or change in region’s average temperature for certain period (May, 2011). In a broader view, climate change can also be seen as change in Earth’s climate with an example being global warming.
Climate change is one of the most important challenges of humankind in this century. The ability to adapt, mitigate and reduce carbon emissions will be decisive to preserve the world for future generations. The last IPCC report has provided more evidence regarding the rise in temperature and sea level. Apparently, additional 2°C above the pre-industrial average temperature levels is unavoidable, and it will continue at that level due the accumulation of gases in the atmosphere (Solomon 2009). Climate change will affect people all around the world in different ways, though the capacity to cope with it is different among regions and countries. The Latin America region is notably susceptible to climate change, due its geographical position, population location and its economy relying in natural resources (Vergara et. al. 2013a). The withdrawal of the coral biome, glaciers melting, jungles & forest savannization and strongest climate events are only some of the threats that will affect their inhabitants.
Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).
When you hear the words “climate change” what comes to mind? Probably weather and the changes. Many of us watch the news or use an app on our cellphones/electronic devices to keep an eye on the weather for the day, week, or even the month. But, there is actually a difference between weather and climate. Weather is actually “the changes we see and feel outside from day to day. It might rain one day and be sunny the next. Weather also changes from place to place” (Dunbar, 2014). Whereas “climate is the usual weather of a place. Climate can be different for different seasons. Different places can have different climates” (Dunbar, 2014). This paper will focus on the ins and outs of climate change, specifically focusing on what climate change
Climate Change is the significant change in the climate and distribution of weather patterns on Earth ranging from the last decade to millennia earlier.
Climate change can be defined as a long-term change in weather environments that include wind, precipitation, and temperature. The direct result of climate change can lead to a change in weather patterns that can last for extended periods of time (Climate Change Summary). Climate change may also be referred to as a change in average weather conditions, which could lead to an increase or decrease in extreme weather events. Recently climate change has been recognized as a problem around the world, while other groups believe climate change is made up of fictional data. Climate change is an ongoing problem in the scientific community, but society has not fully accepted the principles of climate change.
Climate change is defined as “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” Climate change has happened as a cycle throughout history, with ice ages occurring, and then warming. The earth naturally warms and cools, but due to the burning of fossil fuels the rate is growing exponentially.
Global climate change is always happening. There have been periods where the Earth's climate has been warmer than it is now. There have been periods when the Earth’s climate has been cooler than it is now. times These periods can last thousands or millions of years. The scientists who have been watching and studying Earth’s Climate have seen that over the last 100 years the temperatures have been steadily rising by about one-degree Fahrenheit each year. This may not seem like much, but even small changes in Earth's temperature can have big effects on the
Climate change could be described as any process that causes adjustment to climate system be it a volcanic eruption to a change in the solar activity. Today, however, the phrase is most often used as climate change caused by humans. Climate change is also used commonly with another phrase – "global warming" – reflecting scientific observations of strong warming trends over the past century or so. Indicators like rising sea levels, retreating snow cover and glaciers, longer growing seasons and shifting wildlife has alarmed scientific community unanimously agreeing that the earth has warmed in the last century. Experts however are of the opinion that climate change is a more accurate phrase than global warming as the latter is just one component affecting the larger climate systems of the earth.
