I thing the biggest problem in the world today is natural disaster. The main cause of Global warming is human. Global warming is already having significant and harmful effects on our communities, our health, and our climate. Sea level rise is accelerating. The number of large wildfires is growing. Dangerous heat waves are becoming more common. Extreme storm events are increasing in many areas. More severe droughts.
Solutions to Global Warming
There is no single solution to global warming, which is primarily a problem of too much heat-trapping carbon dioxide (CO2), methane and nitrous oxide in the atmosphere.
Boosting energy efficiency: The energy used to power, heat, and cool our homes, businesses, and industries is the single largest contributor to global warming. Energy efficiency technologies allow us to use less energy.
Greening transportation: switching to low-carbon fuels, and reducing vehicle miles traveled
Revving up renewables: Renewable energy sources such as solar, wind, geothermal and bioenergy are available around the world. Renewable technologies can be deployed quickly, are increasingly cost-effective, and create jobs while reducing pollution.
Managing forests and agriculture: reducing emissions from deforestation and forest degradation.
