What is Climate Change?

Long-term shifts in global temperatures and weather patterns Caused by increased greenhouse gases in the atmosphere Human activities are the main driver since the 1800s Carbon dioxide levels have increased by 40% since pre-industrial times

New Zealand's Climate Trends

Environmental Impacts in New Zealand

{"left":"Rising sea levels threatening coastal communities\nGlacial retreat in the Southern Alps\nChanging rainfall patterns affecting rivers and lakes\nOcean acidification harming marine ecosystems","right":"Increased frequency of extreme weather events\nShifts in native species distribution and breeding patterns\nCoral bleaching in northern waters\nAlpine vegetation moving to higher altitudes"}

Impact Investigation Activity

Work in pairs to research one specific climate impact on NZ Choose from: glacial retreat, sea level rise, species migration, or extreme weather Find 3 specific examples with dates and locations Prepare a 2-minute presentation for the class Use NIWA or DOC websites for reliable data

Social Impacts on New Zealand Communities

Māori communities face threats to cultural sites and practices Coastal towns experiencing flooding and erosion Farmers adapting to changing growing seasons Tourism industry affected by environmental changes Health impacts from extreme weather and air quality

Discussion Question

How might climate change affect your local community in the next 20 years? Consider: • Geographic location and elevation • Local industries and economy • Infrastructure and housing • Cultural and recreational activities

Economic Impacts and Costs

Agriculture: changing crop yields and growing seasons Insurance costs rising due to extreme weather damage Infrastructure repairs from flooding and storms Tourism losses from environmental degradation New opportunities in renewable energy sector Estimated cost: $36 billion by 2100 without action

New Zealand's Response and Solutions

Zero Carbon Act passed in 2019 Commitment to net-zero emissions by 2050 Investing in renewable energy and public transport Protecting and restoring native ecosystems Climate Change Commission providing independent advice Supporting communities to adapt and prepare

Action Planning Activity

Individual reflection: What can you do to help? Create a personal climate action plan with 3 specific goals: • One action to reduce your carbon footprint • One way to prepare for climate impacts • One way to influence others positively Share ideas with a partner and get feedback
