Seagrasses under Times of Change View all 8 Articles. During the last years, the tropical seagrass species Halophila stipulacea has established itself in the southern and eastern parts of the Mediterranean Sea. More recently , Halophila decipiens was observed for the first time in the eastern Mediterranean, and was described as the second non-native seagrass species in the Mediterranean Sea. We implemented a species distribution model SDM approach to 1 hindcast the habitat suitability of H. In addition, a principal component analysis PCA and k -means cluster based on temperature and salinity drivers were applied to visualize the distance and relatedness between the native and invasive H. Results from this PCA suggest that the H. Climate Change Influences The Global Potential Distribution

Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid. Throughout geological history, the development of deserts has occurred naturally; however, when deserts emerge due to unchecked depletion of nutrients in soil that are essential for it to remain arable, then a virtual "soil death" can be spoken of, [5] which traces its cause back to human overexploitation. Desertification is a significant global ecological and environmental problem with far-reaching socio-economic and political consequences. As recently as , considerable controversy existed over the proper definition of the term "desertification. However, this original understanding that desertification involved the physical expansion of deserts has been rejected as the concept has evolved. There exists also controversy around the sub-grouping of types of desertification, including, for example, the validity and usefulness of such terms as "man-made desert" and "non-pattern desert".

Use the controls in the far right panel to increase or decrease the number of terms automatically displayed or to completely turn that feature off. Scientific skepticism is healthy. Scientists should always challenge themselves to improve their understanding.

Yet this isn't what Infljences with climate change denial. This website gets skeptical about global warming skepticism. Do their arguments have any scientific basis? What does the peer reviewed scientific literature say? Let us first examine the post-industrial revolution warming and some of the telltale signs that humans are responsible. Then we will explore how we know that the recent increase in greenhouse gases is due to human activity. This also rules out the sun, as an increase in solar energy would heat the whole atmosphere.

Hemispheres receive less sunlight in winter and cool down by radiating energy away into space.

If greenhouse gases were increased, they would act to prevent some of that energy from radiating away, thus warming the winter hemisphere. The warming effect on winter was predicted to be greater than that of summer. These too show that the recent global warming trend cannot be explained without the additional greenhouse gases humans have released into the atmosphere. This too can be quantified.

Figure 1. Examples of human fingerprints on global warming. Read more Atmospheric Distrigution has increased by more than parts per million since the Industrial Revolution in the mids, when humans began burning fossil fuels like coal and oil. Human activity has increased CO2 to levels not seen in the pastyears. To understand atmospheric CO2 levels, we must look to the carbon cycle.

The carbon cycle allows us to track the CO2 being Climate Change Influences The Global Potential Distribution into the atmosphere and absorbed by the planet. In reality public information continue reading hazards and risks is a perfectly normal moral obligation, hardly a transgression of the "correct" role for a researcher. This is a puzzling outcome, akin perhaps to an engineer arranging a safety belt for vehicle occupants but not being allowed to say what safety belts do or how to use them.

What we do

At this juncture a significant proportion of climate research is effectively safety research. Commensurately, expecting the general public and policy makers to guess at significance of findings with negative impacts on the wider well being is clearly not Climate Change Influences The Global Potential Distribution. For the general Influemces benefit a key skill for any given researcher is ability to "join up" immediate findings with the bigger picture. More, please. The full statement. Our current climate crisis poses an existential threat unlike any that our species has experienced before. Emerging evidence suggests that the rapid increase in global average temperature will wreak havoc on not only our climate system, but more info our day-to-day lives.

Inglobal average temperature was 0. While we are already seeing the effects of a changing climate, scientists warn of significantly worsening impacts if warming is not kept below 1.]
