Warmer winters favor insect migration. Insect borne diseases are swarming northward. 6) Dengue fever is now endemic in South Florida. 7) Yellow fever is now moving northward. 8) West Nile Virus has increased in frequency and range as a result of climate change . 9) Malaria cases expected to increase by 50 – 80 million by 2100 AD. 10) Diseases carried by rodents are increasing as more rodents survive milder winters.

Pests Moving Northward African bees (which are much more aggressive towards humans than native species of bees) have been moving northward into the southern United States. These bees were introduced into South America in the past and continue to expand their range into the continental USA. Red fire ants were first discovered in Los Angeles in 1999. The bite of this species of ant is very painful. Roof rats have also expanded into the USA. These rats carry hanta virus and bubonic plague.

Impact of Climate Change on Animal Species: Changing habitats and climates, especially threaten endangered species, pushing some near the brink of extinction. Leads to: food scarcity loss of habitat shifts to crucial migration patterns

Impacts of Climate Change on Crop Production and Human Food Supply (Effects on Agriculture with More Carbon Dioxide in the Atmosphere.) 1) Drier conditions, especially in the USA Midwest and the Ukraine, lead to food production declines in the world’s breadbaskets. 2% increase in temperatures brings a 10% drop in precipitation in the USA Midwest and the Ukraine.

2) With climate change weather events are likely to become more extreme; more devastating violent weather (like hail and heavy downpours) that will destroy crops. 3) Earlier snow melt leads to earlier soil moisture deficit. Decreased soil moisture enhances summer dryness and leads to greater chance of crop collapse in mid-season. (Moisture deficit at a critical time in a crop’s life cycle.) Drought at pollination time especially effects corn. Corn is two thirds of the USA grain crop. 4) Less water available for irrigation in the west. 5) Peach trees replace apple trees in New England orchards.

6) Increase in weeds/pathogens/pests with warmer temperatures and higher levels of carbon dioxide in the atmosphere. a) With more carbon dioxide, crop plants have more carbohydrates and less protein. b) leafy species are affected most. c) fruit, grain, seed crops are not enhanced by more carbon dioxide. d) weedy species thrive e) insects and pests increase in numbers because of warmer temperatures 1) Pests complete more life cycles. 2) They are also more likely to be effective throughout the winter. . 3) Locusts, aphids, and moths are more active and fecund with temperature and humidity increases.

Sea Level Rise Sea level has risen one foot during the 20 th Century along the Atlantic Coast of the USA, but the rate of sea level rise today is accelerating . Estimates are that if present trends continue, globally sea level will rise: 2030 – one additional foot 2040 – two to two and one half additional feet 2100 – three to 10 additional feet. Thermal expansion, resulting from ocean waters becoming warmer, is responsible for about 25% of measured sea level rise. (Warm water expands and thus takes up more space (volume) than cooler water.) Storm surge levels will increase proportionate to sea level rise.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
