🟢 Global Warming & Sea Level Rise
Global mean surface temperature continues to climb, and sea level has risen by about 20 cm since 1880, accelerating in the last few decades.
🔴 Extreme Weather Events
Heatwaves, intense rainfall, and tropical storms are becoming more frequent and severe, consistent with a warmer, moister atmosphere.
🟣 Urban & Human Health Impacts
Cities amplify heat through the urban heat island effect, worsening air quality and heat-related illnesses among vulnerable groups.
🟠 Record CO₂ Levels (2024 Case Study)
Atmospheric CO₂ reached an all-time high in 2024, driving ocean acidification, biodiversity stress, and economic losses.
Bottom Line: Cutting CO₂ emissions delivers immediate co-benefits, cooler cities, healthier populations, and greater climate resilience.
1️⃣ Global Temperatures & Sea Levels
What we see: A clear, persistent warming trend and accelerating sea-level rise.
Why it matters: Warmer oceans and melting land ice are increasing coastal flooding risks, demanding both adaptation and mitigation.
2️⃣ Extreme Weather Events
What we see: Growing frequency of heatwaves, heavy rain events, and storm-related damages.
Why it matters: These extremes strain infrastructure and budgets, highlighting the need for heat-action plans and updated design standards.
3️⃣ Urban & Human Health
What we see: Urban heat islands raise night-time temperatures; stagnant air worsens PM₂․₅ and ozone levels.
Why it matters: Cooling measures (green roofs, shade trees, reflective pavements) improve both climate and public-health outcomes.
4️⃣ Case Study – Record CO₂ in 2024
What we see: CO₂ spiked to record highs due to fossil-fuel use and an El Niño-amplified carbon cycle.
Why it matters: Confirms urgency — targeting top emission sources yields the fastest, largest gains.
Electric Power:
Expand renewables and improve grid efficiency.
Buildings & Cities:
Retrofit for energy efficiency; adopt cool-roof standards.
Transportation:
Electrify fleets and enhance public transit.
Public Health:
Establish heat alerts, clean-air shelters, and outreach for at-risk groups.
