Natural Health Impacts of Global Climate Change Crispin Pierce, Ph.D. piercech@uwec.edu Environmental Public Health Program

Slide 2

Outline Global Human Environmental Threats Experiment Challenge Direct Human Effects Heat passings Adverse climate occasions Costs of amazing climate occasions Relationship Between Climate Change and Other Environmental Issues

Slide 3

Associated Climate Changes and Surprises Flooding of Low-Lying Areas Spread of Waterborne Diseases Climate Change and Food Production Effects on Plant and Animal Communities Phenology Greening of the North Coral Bleaching Species Extinction Benefits of Stabilizing CO 2 Concentrations

Slide 4

Global Human Environmental Threats Overpopulation Global Climate Change Loss of Biodiversity

Slide 5

Experimental Challenge A columnist for the Eau Claire Leader-Telegram gets in touch with you for data on an article concerning a dangerous atmospheric devation. She makes the inquiry, “If air and ocean temperatures rise, will the softening of ice shelves lead to ocean level increases?” What is your reaction. Utilize the materials before you (ice 3D squares, a graduated chamber, and a water fixture), how might you test your answer?

Slide 6

Direct Human Effects Hotter, Drier Summers and Warmer, Wetter Winters Increased Adverse Weather Events Property and Crop Losses

Slide 7

Quick Quiz About what number of individuals in Europe kicked the bucket amid the warmth wave of 2003? 350 3,500 35,000 Heat is the essential driver of climate related passings.

Slide 8

Adverse Weather Events Increased Sea Surface Temperatures and Greater Hurricane Intensity ( Science 16 September 2005:Vol. 309. no. 5742, pp. 1844 - 1846) Net Hurricane Power Dissipation Highly Correlated with Tropical Sea Surface Temperature ( Nature advance online production; distributed online 31 July 2005 | doi: 10.1038/nature03906)

Slide 9

Costs of Extreme Weather Events

Slide 10

Relationship Between Climate Change and Other Environmental Issues The intricate impacts of warming of our air, water, and soil are exceptionally hard to gauge and anticipate. Collection of proof from numerous fields, for example, science, science, geography, and ecological wellbeing is fundamental. The amassed confirmation gives a clearer and clearer picture of what’s going on.

Slide 12

Associated Climate Changes Global ocean level has expanded 1-2 mm/yr; in 100 years an ascent in ocean level somewhere around 3.5 and 34.6 in. (9-88 cm) is normal Duration of ice front of waterways and lakes diminished by 2 weeks in N. Side of the equator Arctic ice has diminished considerably, diminished in degree by 10-15%

Slide 13

Reduced permafrost in polar, sub-polar, rocky locales Growing season stretched by 1-4 days in N. Side of the equator Retreat of mainland icy masses on all landmasses Snow spread diminished by 10% (lessened sun powered reflection) Source: Intergovernmental Panel on Climate Change, 2001 Report

Slide 14

Since 1979, the mid year's extent polar ice top has contracted more than 20 percent. (Representation from NASA) ( http://www.nrdc.org/globalWarming/qthinice.asp)

Slide 20

Who Will be First Affected? AOSIS is a coalition of little island and low-lying seaside nations, including Africa, Caribbean, Indian Ocean, Mediterranean, Pacific, South China Sea These nations offer danger elements for warming-incited catastrophes: Small physical size Surrounded by substantial spans of sea Relative separation Limited characteristic assets Growing populaces Exposure to harming normal calamities Low financial enhancement Limited trusts, HR, aptitudes

Slide 21

Rising ocean levels will bring about Displacement of waterfront groups Disturbance of rural action Coastal disintegration, shoreline misfortune, decrease in tourism Intrusion of ocean water into freshwater aquifers

Slide 23

Other dangers confronted by AOSIS More incessant dry spells and surges Water supply tainting The experience of AOSIS nations is a microcosm of the worldwide picture

Slide 24

Spread of Waterborne Diseases Malaria Dengue Fever Cholera Typhoid fever Hantavirus Diptheria Lyme Disease Evidence: the Caribbean locale has encountered a stamped increment in the occurrence of dengue and dengue hemorrhagic fever in the previous decade (Caribbean Epidemiology Center - CAREC).

Slide 25

Climate Change and Food The development of harvests relies on upon numerous components, including temperature, precipitation, soil fruitfulness, and encompassing area employments. Great climate occasions (dry season, storms, surges, and so on.) are exceptionally harming to trims. The impacts of more steady influences (e.g., normal temperature increment) are hard to anticipate. Creating nations will be much harder hit than created nations, because of constrained farming adaptability.

Slide 28

Effects on Plant and Animal Communities The impacts are hard to quantify, yet possibly emotional. Numerous species possess correctly limited environmental corners, thus little changes in atmosphere can bring about interruptions in living space or sustenance accessibility. Before, portable creatures could react to these weights by moving starting with one place then onto the next. Land improvement, on the other hand, has compelled and divided ranges and travel courses, making relocation a great deal more troublesome. Loss of key predator or prey species influences the life cycles of different creatures in the evolved way of life.

Slide 30

Greening of the North More vegetative development in the most recent 20 years. Numerous researchers anticipate more noteworthy desertification. Ranga B. Myneni, Department of Geography, Boston University

Coral Bleaching Increased ocean temperatures Increased CO2 focuses: http://www.awi-bremerhaven.de/Carbon/calcif.html

Slide 32

Species Extinction of the brilliant amphibian: Over the previous 30 years, the dry season in the Costa Rica’s cloud timberland has gotten to be hotter and drier. 20 out of 50 types of frogs and amphibians have vanished from a 30-square-kilometer study territory Toucans and other feathered creature species have moved their extent to higher heights. Frog termination in the Central and South American tropics

Slide 33

Biological Shifts in the scopes of 35 types of non-transitory butterflies. Decrease in body weight of polar bears, coming about because of right on time softening of ocean ice and brought down sustenance accessibility. Changes in the wealth of winter larks in four Great Plains states Shifts in California’s tidepools species Reduction of phytoplankton development in the Ross Sea that could disturb the Antarctic evolved way of life

Stabilizing CO 2 Atmospheric Levels Efficient Transportation Energy Conservation Sustainable Energy Sources Sustainable Land Use Population Stabilization

Extra Slides Scientists anticipate that proceeded with an unnatural weather change on the request of 2.5â°-10.4°F throughout the following 100 years (as anticipated in the IPCC's Third Assessment Report) is liable to result in: serious weight on numerous backwoods, wetlands, snow capped districts, and other characteristic biological communities more noteworthy dangers to human wellbeing as mosquitoes and other illness conveying bugs and rodents spread infections over bigger topographical locales disturbance of farming in a few sections of the world because of expanded temperature, water anxiety, and ocean level ascent in low-lying zones, for example, Bangladesh or the Mississippi River delta. .:tslide
