It’s all about hype, but it’s not all hype.
That’s the takeaway from the latest report from the Global Greenhouse Gas Inventory (GGGI), a joint venture between the U.S. National Oceanic and Atmospheric Administration (NOAA) and the European Space Agency (ESA).
In the report, the authors write that the current climate model, which predicts a warming world, “has a low likelihood of maintaining global warming under the current trajectory.”
The authors say they’re not expecting a sudden reversal of the planet’s temperature trends in the near term.
“The current forecast is consistent with what we’ve observed in the past and the future projections are similar,” the report states.
“In short, it is not a greenhouse bubble.”
The report comes as the White House has issued a warning to policymakers that a “greenhouse gas bubble” could burst and potentially damage the planet.
The authors also said that the rise of carbon dioxide as a greenhouse gas has caused the rise in the global temperature.
The report notes that the oceans and the atmosphere have not warmed as much as expected.
“At present, global mean surface temperatures have risen about 1.8°C in the last century, well below the 2°C global mean temperature forecast by the Intergovernmental Panel on Climate Change (IPCC),” the report says.
“This means that ocean surface temperatures and air temperatures are likely to remain within the bounds of their historical average temperatures.”
The global climate is expected to continue to warm as CO2 levels rise.
In fact, according to the report’s authors, the planet is currently warming about twice as fast as it did during the Medieval Warm Period in the Middle Ages.
The warming is causing an increase in CO2 concentrations in the atmosphere.
This is making the oceans warmer.
“During the Medieval warm period, CO2 concentration was about 3 times what it is now,” the authors state.
“Today, CO₂ concentration is about 3.2 times what was present during the early Industrial Revolution.
The increase in atmospheric CO2 is accelerating because CO2 has become so abundant and inexpensive.”
It also leads to an increase of the amount of energy that we can emit.
As a result, the oceans are warming at an exponential rate.
The oceans are the only body of water on Earth where the climate system is able to hold more heat.
“Ocean temperatures have warmed at an average rate of about 0.2°C/century, but ocean temperatures are now 1.3°C warmer than at the end of the Medieval warmth period,” the researchers wrote.
The researchers write that these changes are caused by an increase and contraction of the sea surface, a change in the way the oceans absorb sunlight and a decrease in the amount that water can absorb.
“As a result of this acceleration and contraction, the surface of the oceans is now warming at a rate about 1°C faster than at any time in the recent past,” the scientists wrote.
It’s worth noting that CO2 emissions in the United States and around the world are still at their peak, the report notes.
As of May, U.N. Secretary-General Ban Ki-moon called on the international community to take immediate action to cut emissions and reduce global warming.
“We must immediately halt the rapid increase in emissions of CO2, in particular carbon dioxide, which is the main driver of climate change,” he said in a statement.
“A global carbon budget, with limits on emissions, is needed to avert a catastrophic temperature increase and climate catastrophe.”
While it’s easy to get caught up in the hype, the science is far from conclusive.
The U.K. and Germany are the two countries with the largest carbon footprints, with emissions accounting for about half of the global emissions.
“There are a number of limitations to this report, including the low number of countries in the world, the small number of models used to compute their results, and the fact that this study is based on data from a single country,” the GGI authors wrote.
“Nevertheless, the overall picture is a promising one for the future.”
