Study: Global Pledges To Cut Carbon Emissions Will Actually Help

Study: Global Pledges To Cut Carbon Emissions Will Actually Help. A climate research group says carbon emissions cuts pledged by governments could rein in global warming by up to 1 degree C (1.8 degrees F) by 2100.

On Thursday – the deadline for submitting pledges for a U.N. climate pact – the Climate Action Tracker group said if fully implemented, the emissions targets would result in 2.7 C (4.9 F) of warming compared to pre-industrial times. Without those cuts, the group calculated that there would be an additional 0.5-1.1 C (0.9-2.0 F) of warming. A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earth’s atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O₃). Without greenhouse gases, the average temperature of Earth’s surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F). The atmospheres of Venus, Mars and Titan also contain greenhouse gases.

Currently, temperatures are about 1.8 C (3.2 F) warmer than in pre-industrial times.

A separate analysis this week by the U.S.-based Climate Interactive group projected 3.5 C (6.3 F) of warming based on the current pledges. Study: Global Pledges To Cut Carbon Emissions Will Actually Help

All major carbon polluters except India submitted targets by Thursday.
