Modern climate change is dominated by human influences, which are now large enough to exceed the bounds of natural variability. The main source of global climate change is human-induced changes in atmospheric composition. These perturbations primarily result from emissions associated with energy use, but on local and regional scales, urbanization and land use changes are also important. Although there has been progress in monitoring and understanding climate change, there remain many scientific… 
A Review on the Causes, Effects and Mitigation of Climate Changes on the Environmental Aspects
Abstract Climate change is often used interchangeably with the term global warming but, it is a much broader term which includes global warming and some other climate changes that are observed on our
Climate change
Global climate change is signifi cantly altering the structure and functioning of many ecosystems and, consequently, temporal and spatial patterns of population and species abundance (e.g. Stenseth
Climate Change, Human Impacts, and Community Structure
Since the Industrial Revolution, anthropogenic influences have assumed a major role that will shape future global climate change. Additionally, evidence is emerging that human impact on climate can
Global Warming and Global Change: Facts and Myths
The phenomenon of global warming taking place today is widely believed to be a consequence of increased anthropogenic CO 2 rising in the atmosphere. In reality, the greenhouse gas effect is more
Multidimensional analysis of global climate change: a review
TLDR
Climate change politics and coverage of climate change episodes in mass media is the special focus of this review that concludes with a few mitigation measures.
Climate Change, Mortality, and Adaptation: Evidence from Annual Fluctuations in Weather in the US
The climate is a key ingredient in the earth’s complex system that sustains human life and well-being. There is a growing consensus that emissions of greenhouse gases due to human activity will alter
River Floods in the Changing Climate—Observations and Projections
River flood damages, worldwide, have increased dynamically in the last few decades, so that it is necessary to interpret this change. River flooding is a complex phenomenon which can be affected by
THE INTERACTION BETWEEN GLOBAL CLIMATE CHANGE AND TROPICAL FOREST ECOSYSTEMS
In the last 100 years, the global mean temperature has increased approximately 0.6oC and is predicted to increase approximately 1.1oC to 6.4oC in the end of 21st century. On the other hand,
Precipitation drives global variation in natural selection
TLDR
It is reported that aspects of precipitation and potential evapotranspiration, along with the North Atlantic Oscillation, predicted variation in selection across plant and animal populations throughout many terrestrial biomes, whereas temperature explained little variation.

The Human Impact on Climate
There is a strong suspicion that climate change occurs under the influence of carbon dioxide. According to the data of the last century it is 26 times smaller in the atmosphere than the water vapor.

Tropical Origins for Recent North Atlantic Climate Change
TLDR
Evidence is presented that North Atlantic climate change since 1950 is linked to a progressive warming of tropical sea surface temperatures, especially over the Indian and Pacific Oceans, which has forced a commensurate trend toward one extreme phase of the North Atlantic Oscillation during the past half-century.

Interpretation of High Projections for Global-Mean Warming
TLDR
This work interprets the new warming range in probabilistic terms, accounting for uncertainties in emissions, the climate sensitivity, the carbon cycle, ocean mixing, and aerosol forcing, and shows that the probabilities of warming values at both the high and low ends of the TAR range are very low.

TLDR
It is found that the amount of BC in current climatologies must be increased by a factor of 2–4 to yield best agreement with AERONET, in the approximation in which BC is externally mixed with other aerosols.
