  1. PLANETARY NETWORKS: CLIMATE CHANGE Prepared by: CHERRYLYN T. MAGANO LPT
  2. Change is inevitable. The era of globalization certainly contributed in changing the landscape of the world and its inhabitants. Amid this growth and advancement in technology, the environment seems to bear and suffer the consequences. Every day, we are confronted with issues and problems related to the environment. The issue on climate change is one concrete manifestation and realization that the age of globalization and the rapid industrial and technological advancement has taken its toll on the natural environment.
  3. Climate Change - Also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. - Is “a change of which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere” (United Nations Forum Convention on Climate Change)
  4. Greenhouse Effect – the trapping of the sun’s warmth in a planet’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface.
  5. 7 EFFECTS OF CLIMATE CHANGE YOU’RE ALREADY SEEING Climate change isn’t something that’s happening in 10 or 20 years. It’s happening now. Here are seven effects of climate change you’ve already seen.
  6. 1. LONGER, MORE INTENSE ALLERGY SEASONS. Warming temperatures in some areas, like the northern United States, are extending the periods when plants release pollen. This affects not only people who already have allergies, but those who didn’t. This means that people who have pollen allergies might experience ,ore intense symptoms, and people who don’t normally have allergies might begin to experience them. This pollen can induce allergic asthma.
  7. 2. FOODS YOU LOVE ARE BECOMING LESS NUTRITIOUS AND CAUSE MORE AT THE GROCERY STORE The same CO2 accumulating in our atmosphere thanks to fossil fuels is actually changing the composition of fruits and vegetables that we eat, making them less nutritious. The extra CO2 is speeding up photosynthesis and causing plants to grow with more sugar and less calcium, protein, zinc, and important vitamins.
  8. Not only food is becoming less nutritious, but it could soon cost more too. Beginning in 2006, drought in major wheat-producing countries was a key factor in a dramatic spike in food prices around the globe. And as the world keeps getting hotter, we can expect to see this kind of drought more and more often.
  9. 3. MORE COMMON, MORE SEVERE, AND MORE LONG-LASTING HEAT WAVES. Extreme heat and heat waves have happened since the beginning of time. But across the board, climate change is making heat waves more common, severe, and long-lasting. Heat waves can become so intense that our roads actually melt.
  10. 4. WILDFIRE CAUSING DAMAGE TO OUR LANDSCAPES AND OUR COMMUNITIES – AS WELL AS OUR HEALTH. Wildfire are devastating communities around the world. From the billion-dollar destruction they cause to the costs of lost plant, animal, and even human life, these devastating natural disasters are scarring our landscapes.
  11. 5. HURRICANES ARE BECOMING MORE LIKELY AND MORE DANGEROUS. Around the world, average sea surface temperatures are rising. As seas get warmer, they add more water vapor and heat energy into the atmosphere. This extra heat and water, just happens to be the perfect fuel for hurricanes and in the right conditions, can make dangerous storms even more powerful.
  12. 6. MORE CLIMATE-RELATED MASS MIGRATION. Climate change is already prompting an increase in migration, with people being forced to leave their homes because of drought, flooding, and other climate-related disasters.
  13. 7. DISEASES ARE SPREADING MORE EASILY. Disease-carrying insects thrive with warmer-than-average temperatures, extreme heat waves, and heavy rains. These vectors live longer lives in extended periods of warm weather. Fly into new areas that were previously too cold. And reproduce in water deposits left by the rain. Climate change is also creating ideal conditions for waterborne pathogens like bacteria, viruses, and protozoa, which flourish in warmer waters.
  14. Solutions:  What to do:  Reduce energy consumption  Travel Green  Watch your Water Use  Reduce Waste  Plant a Tree
  15. Climate Change Solutions In order to avoid the most serious impacts of climate change, humans will have to significantly reduce the amount of greenhouse gas emissions being put into the atmosphere. There are different approaches to make these decreases, including optimizing vehicles proficiency, expanding access to and utilization of open travel, overhauling building protection, supplanting fossils with renewable energy, and diminishing deforestation.
  16. Numerous legislatures, organizations, and people are starting to execute some of these techniques and hence gradually decreasing emissions. The use of cleaner production technologies and change of lifestyle are desired to impact a change in climate.
