With Focus on the British Isles how in 50 years time will climate change effect plant productivity and biodiversity. http://www.pnas.org/content/104/50/19686.full Plant productivity is expected to be strongly affected by climate change within the next 50 years. Lobell et al. (2011) showed that climate trends since 1980 were large enough in many countries to offset a significant proportion of the potential increases in average crop yields due to technological advances‚ CO2 fertilization and other

Natural Causes of Climate Change The earth’s climate is influenced and changed through natural causes like volcanic eruptions‚ ocean current‚ the earth’s orbital changes and solar variations. Volcanic Eruptions When a volcano erupts it throws out large volumes of sulphur dioxide (SO2)‚ water vapour‚ dust‚ and ash into the atmosphere. Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. Tiny particles called aerosols

common arguments used by climate change skeptics. There is both human caused and non-human caused climate changes. Global warming may be a hoax or due to changes in nature. Natural changes such as sunspots and orbital change has had an effect on climate. Sun spots have been investigated since the 1800’s. Research published by the Journal of Atmospherics and solar terrestrial physics have concluded “the sun has a significant role to play in long-term and short-term climate change.” Another reason may

1. Natural causes of climate change within the model are livestock (cows) producing methane gas. Human-made causes that can be seen are deforestation for crops‚ homes‚ and businesses. Pollution from cars and planes realeases CO2 into the air and the use of electricty to run the homes and businesses creates greenhouse gases. From 1775 till today‚ cars and planes have been created and contribute to green house gas production. The population has increase and more crops and homes have been built. Oil

In this essay I will explain the natural causes of climate change I will talk about the Milankovich cycles‚ sun spots and also volcanoes and cosmic. Milankovich cycles consist of 3 different variations of cycles the first one is orbit which changes the earth’s orbit from spherical to elliptical this happens every 100 thousand years this changes the earth’s solar input. During the elliptical years the summers are very hot and the winters are very cold however when it is the spherical the weather

Suggest ways in which climate change might affect Africa’s physical environment? Many things will happen to Africa’s physical environment as climate change happens‚ however the main ones will be: decreased or no change in crop growing with some even going down over 20%‚ decreased rainfall in parts where there already is only 1-100mm a year anyway; it contains around 29% of the world’s mammals‚ birds and plants and also 17% of the amphibians and reptiles‚ and finally Africa has a lot of low lying

In recent years‚ due to the constant change of climate‚ floods‚ droughts‚ landslides‚ and storms have frequented our earth‚ the only human habitat. Therefore‚ climate change has become one of the most important issues in many urban areas of many countries and it is a serious impact on them. There is half of the world ’s population in urban areas and the proportion will increase rapidly in future years. Climate change is a mean state of the climate or in its variability‚ continue for a long period

Global Climate Change and its Effects A simple way to describe Global warming would be to say that it refers to an average increase in the Earth ’s temperature and this increase may cause changes in climate. As the Earth warms up it may lead to significant rise in sea levels‚ chaotic weather patterns‚ and catastrophic droughts. When we talk about the issue of climate change‚ what we are really concerned about is the global warming caused by human activities. In my opinion‚ Global warming is already
