CLIMATE CHANGE

• ‘We’ve been trying to warn you for so many decades’: Nasa climate scientist breaks down in tears at protest. Peter Kalmus and others were later arrested after blocking the entrance to a JP Morgan-Chase building

  in LA.
• Climate change is a hoax
• Greenhouse gases

  • Water vapor
  • Carbon dioxide (CO2)
  • Methane
  • Nitrous oxide
  • Chlorofluorocarbons (CFCs)
• The Greenhouse Effect - The Earth is surrounded by a thin layer of gasses we call greenhouse gases. These gases are what make up our atmosphere.
• Some sunlight that hits the earth is reflected. Some becomes heat.
• Co² and other gases in the atmosphere trap heat, keeping the earth warm.
• The thickness of the atmosphere and the concentration of its

  gases influence the surface temperature on any planet.
• Water vapor - The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.
• Carbon dioxide (CO2) - A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels.
• Methane - A hydrocarbon gas produced both through natural

  sources and human activities, including the decomposition of

  wastes in landfills, agriculture, and especially rice cultivation, as

  well as ruminant digestion and manure management associated with domestic livestock.
• On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere
• Nitrous oxide

  • A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.
• Chlorofluorocarbons (CFCs)


  Synthetic compounds entirely of

  industrial origin used in a number of applications, but now

  largely regulated in production and release to the atmosphere

  by international agreement for their ability to contribute to

  destruction of the ozone layer. They are also greenhouse

  gases.
• GLOBAL WARMING

  Is the increase of the Earth’s

  average surface temperature

  due to a build-up of greenhouse gases in the atmosphere.
• CLIMATE CHANGE

  Is the long-term changes in

  climate, including average

  temperature and precipitation.
• Climate change


  It recognizes that, although the

  average surface temperature

  may increase, the regional or

  local temperature may

  decrease or remain constant
• EFFECTS OF CLIMATE CHANGE

  • Hotter temperature
  • More severe storms
  • Increased drought
  • A warming, rising ocean
  • Glaciers are melting
  • Loss of species
  • Not enough food
  • More health risks
  • Poverty and displacement
• China


  Biggest carbon dioxide emitters (2015 data) world rank:1
• Top carbon dioxide emitting countries ( 1750-2020) from fossil fuels and cement

  • United States
  • China
  • Russia
  • Germany
  • UK
  • Japan
  • India
  • France
  • Canada
  • Ukraine
  • Poland
  • Italy
• Hotter temperature


  Higher temperatures are worsening many types of disasters,including storms, heat waves, floods, and droughts.

  A warmer climate creates an atmosphere that can collect,

  retain, and drop more water, changing weather patterns in

  such a way that wet areas become wetter and dry areas drier.
• More severe storms


  Scientists are detecting a stronger link between the planet's warming and its changing weather patterns. Though it can be hard to pinpoint whether climate change intensified a particular weather event, the trajectory is clear — hotter heat waves, drier droughts, bigger storm surges and greater snowfall.
• Increased drought


  Warmer temperatures enhance evaporation, which reduces

  surface water and dries out soils and vegetation
• A warming, rising ocean


  Global sea levels are rising as a result of human-caused

  global warming
• Glaciers are melting


  So are ice caps on both North and South

  poll. Pictured example: Portage Glacier,

  Alaska
• Loss of species


  Global warming is projected to commit over one-third of the

  Earth's animal and plant species to extinction by 2050 if

  current greenhouse gas emissions trajectories continue
• Not enough food


  Climate change can disrupt food availability, reduce access

  to food, and affect food quality
• More health risks


  Climate change is already impacting health in a myriad of ways, including by leading to death and illness from increasingly frequent extreme weather events, such as heatwaves, storms and floods, the disruption of food systems, increases in zoonoses and food-, water- and vector-borne diseases, and mental health issues.
• Poverty and displacement


  Without urgent action, climate change could push an additional 100 million people into poverty, says the World Bank.
• CAUSES OF CLIMATE CHANGE

  • Generating power
  • Manufacturing goods
  • Cutting down forests
  • Transportation
  • Food production
  • Consuming too much
• Generating power


  Energy is at the heart of the climate challenge – and key to the solution. Generating electricity and heat by burning fossil fuels – coal, oil, or gas – causes a large chunk of the greenhouse gases, such as carbon dioxide and nitrous oxide, that blanket the Earth and trap the sun's heat
• Manufacturing goods


  Manufacturing – especially of the cheap construction staples steel and cement – accounts for about a third of global greenhouse gas emissions.
• Cutting down forests


  Cutting trees both adds carbon dioxide to the air and removes the ability to absorb existing carbon dioxide.
• Transportation


  Greenhouse gas (GHG) emissions from transportation account for about 29 percent of total U.S. greenhouse gas emissions,
• Food production


  Food system activities, including producing food,transporting it, and storing wasted food in landfills, produce greenhouse

  gas(GHG) emissions that contribute to climate change.
• Consuming too much


  Overconsumption worsens climate breakdown and increases air pollution.

  It exhausts the planet's life support systems like the ones that provide us with fresh water,

  and leaves us short of materials critical to our health and quality of life.
• Industrialization


  A product of the innovation of man to make thier work easier and to increase production in a short period of time.
• Simple actions to help tackle the climate crisis

  • Save energy at home
  • Walk, cycle or take public transport
  • Eat more vegetables
  • Consider your travel
  • Throw away less food
  • Reduce, reuse, repair, and recycle
  • Change your home's source of energy
  • Switch to an electric vehicle
• Burning of fossil fuels
