The amount of CO2 in the atmosphere this year is forecast to be 419.2 parts per million (ppm), according to the Mauna Loa observatory in Hawaii. The global average last year was 417.2ppm . In the Scientists already have documented these impacts of climate change: Ice is melting worldwide, especially at the Earth's poles. This includes mountain glaciers, ice sheets covering West Antarctica Scientists warn that humans must limit the rise in global average temperature to less than 2.7 degrees Fahrenheit (1.5 degrees Celsius) to avoid the most catastrophic effects of climate change Extreme heat and poor air quality increase complications from underlying heart and respiratory conditions like asthma, renal failure, and pre-term birth, and as temperatures rise, there will be more heat-related illness and deaths in both urban and rural areas. Americans will be exposed to more frequent and/or intense extreme weather and Rising seas, floods, and intensifying cyclones are just a few of the impacts that make Bangladesh one of the most climate change-vulnerable countries in the world. Few countries on Earth so exemplify the deep inequity of the climate crisis as Bangladesh. Despite producing only 0.56% of the global emissions changing our climate, Bangladesh ranks Many climate change impacts are already felt at the current 1.2 °C (2.2 °F) level of warming. Additional warming will increase these impacts and can trigger tipping points, such as the melting of the Greenland ice sheet. Under the 2015 Paris Agreement, nations collectively agreed to keep warming "well under 2 °C".However, with pledges made under the Agreement, global warming would still Sea level rise is an increase in the level of the world's oceans due to the effects of global warming.Burning fossil fuels is one of the causes of global warming because it releases carbon dioxide and other heat-trapping gasses into the atmosphere.The oceans then absorb the majority of this heat. As water becomes warmer, it expands. This results in ocean levels rising worldwide. CEzLhQv.
