The health effects are also expected to be more severe for elderly people and people with infirmities or pre-existing medical conditions. Impacts of Climate Change on Food Security 14 1.2. Since the 2006 SAEO, local and global research has advanced its understanding of the projected impacts of climate change . Potential impacts of climate change on food systems and food security, and possible adaptive responses 14 Table 2. Urgent health challenges for the next decade. %PDF-1.3 %���� But we must also prepare for the significant and unavoidable consequences of carbon emissions such as increasing temperatures, shifting precipitaton patterns, ocean acidification, sea level rise and the increasing intensity and frequency of extreme weather events. The quantities of emissions involved are enormous. Climate change, the periodic modification of Earth’s climate caused by atmospheric changes and the atmosphere’s interactions with geologic, chemical, biological, and geographic factors. This report has four primary sections: Section 2 begins by providing a broad overview of climate change impacts on biodiversity and introducing an analytical framework that structures the assessment. Ice is melting worldwide, especially at the Earth’s poles. 223 0 obj << /Linearized 1 /O 225 /H [ 707 788 ] /L 972831 /E 134671 /N 50 /T 968252 >> endobj xref 223 14 0000000016 00000 n 0000000631 00000 n emitted globally, and how sensitive the Earth’s climate is to those emissions. climate change will likely increase the number of people suffering from illness and injury due to floods, storms, droughts, and fires, as well as allergies and infectious diseases. Past climate trends and future climate projections for BC are then While certain effects of climate change can be beneficial, particularly in the short term, current and future effects of climate change pose considerable risks to people’s health and welfare, and the environment. A lack of safe water can compromise hygiene and increase the risk of diarrhoeal disease, which kills over 500 000 children aged under 5 years, every year. (2) Death toll exceeded 70,000 in Europe during the summer of 2003. �0P!��m� lkZ�h]���I7����_�̠�(E��E! The urgency for adaptation is highlighted by projections from the three reports produced by the IPCC in 2007 (IPCC 2007). the Agricultural Policy/Environmental eXtender (APEX) model to evaluate future climate change impacts and adaptations in Eastern US corn-soybean rotation systems. The level of climate change we will see depends on how quickly we cut emissions of dangerous greenhouse gases. Increasingly variable rainfall patterns are likely to affect the supply of fresh water. allergy icon. trailer << /Size 237 /Info 220 0 R /Root 224 0 R /Prev 968241 /ID[] >> startxref 0 %%EOF 224 0 obj << /Type /Catalog /Pages 215 0 R /Outlines 213 0 R >> endobj 235 0 obj << /S 769 /O 889 /Filter /FlateDecode /Length 236 0 R >> stream Signs of Climate Change. Each of the last 3 decades has been successively warmer than any preceding decade since 1850(1). Impacts from climate change are happening now. 0000003635 00000 n These two pages present the Key Messages from the “Our Changing Climate” chapter of the Third National Climate Assessment report.

These can trigger asthma, which affects around 300 million people. The climate change agenda has risen substantially in global and national importance and the Climate change affects many of the the social and environmental determinants of health – clean air, safe drinking water, sufficient food and secure shelter. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress. Gender and Climate Change 16 Secondly, as some degree of Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time. In Romania, for instance, extreme weather events have multiplied since 2002. urghila et al. Over the last 50 years, human activities – particularly the burning of fossil fuels – have released sufficient quantities of carbon dioxide and other greenhouse gases to trap additional heat in the lower atmosphere and affect the global climate. High temperatures also raise the levels of ozone and other pollutants in the air that exacerbate cardiovascular and respiratory disease. These effects interrelate with each other and increase their violence, putting at risk the species that inhabit the Earth, including the humans.. consequences of climate change are very diverse, and those in low-income coun-tries who contribute least to climate change are most vulnerable to its effects. Health Effects Climate change destabilises the Earth’s temperature equilibrium and has far-reaching effects on human beings and the environment. Although global warming may bring some localized benefits, such as fewer winter deaths in temperate climates and increased food production in certain areas, the overall health effects of a changing climate are overwhelmingly negative. and life as a result of climate change Concerted global action is needed to enable developing countries to adapt to the effects of climate change that are happening now and will worsen in the future. and. In the heat wave of summer 2003 in Europe for example, more than 70 000 excess deaths were recorded. animal icon. Malaria is strongly influenced by climate. 0000001840 00000 n In the “questions” box, note any questions you have, or things you would like to know about the causes and effects of climate change. More than half of the world's population lives within 60 km of the sea. This includes: (1) IPCC, 2014: Summary for Policymakers. For two weeks in May, we traveled across three-quarters of Zimbabwe, researching how climate change is affecting the country. Many scientists argue that the impacts of climate change will be devastating for natural and human systems, and that climate change poses an existential threat to human civilization. One aspect that has been greatly affected by climate change is the weather. While agriculture is a significant contributor to greenhouse gas emissions, it is also a source of carbon storage in soils. They also cause drownings and physical injuries, damage homes and disrupt the supply of medical and health services. 0000002855 00000 n The Aedes mosquito vector of dengue is also highly sensitive to climate conditions, and studies suggest that climate change is likely to continue to increase exposure to dengue. Climate change is so powerful that in recent months it has affected the electricity supply, too. Some greenhouse gases have an atmospheric life-time measured in tens of thousands of years. It places certain species at an increased risk of extinction. In the heat wave of summer 2003 in Europe for example, more than 70 000 excess deaths were recorded(2). Just and equitable decisions on appropriate responses to climate change can only be reached by giving consideration to all those affected by policy actions (or inactions), including future generations.
