40%
What % of those emissions are still in the atmosphere?
50%
How long can carbon remain in the atmospere?
2000 years
How will ocean circulation (climate) be negatively impacted by global warming?
Atlantic and Southern Ocean thermohaline circulation may weaken, altering the transfer of heat by oceans

2022
Average at 10.03 degrees
What was the hottest year on record, globally?
2016 tied with 2020
Which areas will receive more precipitation (climate) as a result of global warming?
Higher latitude areas
Wetter eastern parts of North and South America, northern Europe and northern and central Asia
What is one positive to the climate from global warming?
Arctic temperatures have increased meaning greater snow and ice melt. This increases access to resources in the Arctic such as oil and gas
