Sunlight and high temperatures, combined with other pollutants such as nitrogen oxides and volatile organic compounds, can cause the ground-level ozone to increase.
This can cause cancer and other serious diseases. Another huge problem is that the sea levels are rising worldwide. Also the expansion of ocean water is caused by warmer ocean temperatures.. The temperature is rising which means that ice is melting faster and faster. However, these are not the only problems. Another issue are the greenhouse gasses.
They are gasses which trap heat in the atmosphere. Some greenhouse gases such as carbon dioxide occur naturally by natural processes and other are created and emitted solely through human activities. For example carbon dioxide is entering the atmosphere because of human activities like burning of fossil fuels oil, natural gas, and coal.
All vehicles exhale too much damaging substances. People have been trying to reduce them but the problem is still topical and I think we have to do something like ride a bike not a car to work or school, we should take the shortest route possible, and plan our drive so that we will not backtrack or travel out of our way.
We also may choose a clean-burning fuel, which reduces ozone-forming pollutants and buy a car that produces fewer emissions or runs using an alternative fuel. The taxes of cars should be higher and most of the people will prefer to use the public transport and we will no longer have traffic jams and we will reduce the damaging emissions. As a conclusion, I think that when it can not do both, The UN should prioritize combating climate change over reducing poverty. Of course, poverty is a big issue, which needs a solution but have you ever asked yourself why the poor countries like Bangladesh, Gambia, Zambia are poor and why so many people die?
I think it is better to first stop the changes in climate and then gradually reduce the hunger in the poor countries. Because if we stop the changes, we are going to be healthier and everything around us will be cleaner and it will be how it actually should be. I believe harmony between nature and human beings will return. Ivanichka Ivanova Iliyan Jordanov. You are commenting using your WordPress. Our current knowledge of the observed and expected biological changes, the ecophysiological and genetic mechanisms that drive them on land far exceeds that from ocean systems.
The inaccessibility of aquatic habitats, the large cost involved and the challenging nature of marine research contributes to the gap in the knowledge. To date, predictions of responses to change in animals have been primarily at the species level and based around 2 approaches. The first uses current species range climate envelops and then predicts future ranges by assessing where similar conditions are likely to be from climate models.
Although widely used across studies Kruuk et al. Species ranges lack the knowledge of adaptation rates and genetic and functional tolerance difference within and between populations. Similarly, the conclusions that can be drawn from using physiological approaches are limited, because they predominantly evaluate small numbers of species and because experimental rates of change are usually much faster than natural change.
There is therefore a key requirement to develop an approach that will improve our understanding of assemblage or community level processes and responses. One of the parameters that need to be considered when developing approaches to understanding how communities or assemblages will respond to environmental change, is the identification of the most vulnerable stages of the population.
The loss of such stages could have a great impact in the overall biodiversity. In this context, early life history stages have been identified as the most vulnerable stages to change Pedersen et al. The small body size, reasonably high mass-specific metabolic rates and lower energy reserves, decreases the capability of early life stages to select and migrate towards a suitable habitat, further increasing their vulnerability to climate change Rijnsdorp et al.
Such characteristics will also increase their mortality during periods of adverse environmental condition e. Studies of temperature tolerances of developmental stages in the laboratory are relatively rare, but those that have been conducted do not often show marked differences from temperature limits of adults.
C, but not above. Different species will vary in their responses to warming and this will affect their competitive abilities and fitness, potentially through variations in aerobic capacity and functional capability P?? Small changes in balance in early life history and colonisation stages in marine species are likely to give very large changes in community structure and ecosystem balance. These factors, coupled with the very high ecologically-driven mortality in early life history stages, mean that investigations of warming effects on recruitment and early community development in marine benthic groups are an essential step towards understanding ecosystem level responses to change.
The Antarctic sessile marine benthos Sublittoral sessile epifaunal assemblages are often characterised by similar group of organisms, potentially allowing comparisons of the effects of environmental variation on basic biological and ecological processes to be made between regions.
The Antarctic benthos has been studied from the earliest expeditions and there has been much interest in the rates of biological and ecological processes in relation to other latitudes See reviews by Clarke, However, with notable exceptions Dayton et al.
There is therefore no empirical data that explains the mechanisms and ecological processes involved. The latter is primarily a consequence of sampling difficulties associated with the slow rates of biological processes in the region and loss of equipment through ice impacts during prolonged deployment. Existing studies of benthic assemblages in Antarctica suggest three distinctive characteristics. First, growth in most taxa is slow by comparison with similar taxa at lower latitudes Pearse et al.
This may be due to physiological limitations associated with low temperature, food limitation due to temporally-limited primary production or a combination of these factors Clarke et al. Second, growth in many taxa is highly seasonal, primarily restricted to the summer period of primary production.

The Simple Global Climate Change Essay Formula. An essay on climate change is not overly difficult to write, as long as you enjoy the topic. In fact, things can get very interesting when you start doing the research and unearthing new and interesting facts and stats.
- Climate Change and Sustainable Development This research paper is about climate change with the concept of sustainable development, meaning that it will approach the climate change problem with an . In that case, we talk of a change in climate or climatic change. Various terms used to describe variations in climate, namely, climate variability. Climatic fluctuations, climatic trends, climatic cycles and climatic change, refer to some appropriate time scales and can only be validly used within such time scales.
