"There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris Agreement on climate change," said Petteri Taalas, secretary-general of the World Meteorological Organization (WMO), at the launch of The WMO ...
This figure shows methane concentration in the atmosphere from hundreds of thousands of years ago through 2023, measured in parts per billion (ppb). The data come from historical ice core studies and recent air monitoring sites around the world. Each line represents a different data source. ...
It shows that from 1990 to 2012, these heat-trapping gases that linger in the atmosphere have caused radiative forcing to increase by 32 percent.Carbon dioxide (CO2) was the largest culprit in the rise: it accounted for 80 percent of the increase in overall greenhouse gas concentration. From...
For the same period, the Russian Land Cover map based on MODIS data for 2014 was used to estimate the impact of land cover surrounding the ZOTTO tower on concentration measurements. The analysis showed that in the 75% seasonal cumulative footprint the largest area is occupied by bogs, ...
'The last time the Earth experienced a comparable concentration of CO2 was 3-5 million years ago,' World Meteorological Organization chief Petteri Taalas said The levels of greenhouse gases in the atmosphere, the main driver of climate change, have hit a new record high, the UN said Thursday...
There is growing concern that increasing concentrations of greenhouse gases in the atmosphere have been responsible for global warming through their effect... MM Iqbal,MA Goheer - 《大气科学进展》 被引量: 30发表: 2008年 The Climate Response to the Changing Greenhouse Gas Concentration in the Atm...
aEven if all greenhouse gas emissions were eliminated today, the concentration of gases already in the atmosphere is high enough to produce the global warming effects we are now experiencing and will continue to experience for years to come. 即使今天消灭了所有导致温室效应的气体,气体的集中已经在大...
In conclusion, the greenhouse effect of the Earth's atmosphere is a natural phenomenon that is essential for life on Earth. However, human activities have significantly increased the concentration of greenhouse gases in the atmosphere, leading to a rise in global temperatures and a range of negativ...
The release of certain gases into the Earth’s atmosphere can create a “greenhouse effect”, in which heat becomes trapped and global temperatures rise. While emissions can result from natural causes, they are primarily the result of human activities, especially the burning of fossil fuels for ...
GENEVA, Nov. 22 (Xinhua) -- Heat-trapping greenhouse gases in the atmosphere have reached another new record high, which, with no sign of a reversal trend, is likely to drive long-term climate change, sea level rise and more extreme weather, the World Meteorological Organization (WMO) warne...
