The Biden administration intends to focus more on capturing the carbon emissions of natural gas plants and industrial manufacturing facilities than from coal-fired power, a top Energy Department official said.
It s a shift for the federal government s carbon capture program, which, until recently, has spent significant funds and resources on attaching carbon capture to power plants, especially coal. The Trump administration saw the technology as a lifeline for coal-fired power, whereas the Biden administration views it as essential to decarbonize harder-to-abate sectors of the economy, such as steel, chemical, and cement production.
Carbon capture, which removes carbon from the smokestacks of power plants or industrial facilities to be stored underground, hasn t been widely commercialized yet because it is still costly. However, many climate models and scientific reports, including the United Nations Intergovernmental Panel on Climate Change, say carbon capture
Satellite Images Show Accelerating Retreat of World s Glaciers
In a new study, an international team of researchers have found that almost all of the world’s glaciers are in retreat, and at an accelerating pace.
The study is the first to include all of the world’s approximately 220,000 glaciers, apart from the Greenland and Antarctic ice sheets. For it, they analyzed imagery collected by NASA’s Terra satellite, which has orbited Earth once every 100 minutes at an altitude of almost 700km since 1999.
The images were captured by ASTER, a multispectral imager aboard Terra, that is equipped with two cameras that record pairs of stereo images that allow researchers to create high-resolution digital models of the world’s glaciers. For their findings, the researchers used the full archive of images taken by ASTER to build a time series of glacial elevation, ultimately allowing them to calculate changes in the thickness and mass of ice over time. To process the data, they used
An international research team including scientists from ETH Zurich has shown that almost all the world’s glaciers are becoming thinner and losing mass’

In order to achieve net-zero emissions, the world is committed to achieving carbon-neutral by 2050. The use of renewable energy is a global trend, and many countries are developing hydrogen energy.
London, U.K. (Merxwire) - The United Nations Intergovernmental Panel on Climate Change (IPCC) has warned in recent years that if mankind wants to control the greenhouse effect within a safe range in this century, net zero emissions must be achieved before 2050. The Paris Agreement also called for a global time limit of 2050 carbon-neutral , so advanced countries around the world began to take action and seek clean, renewable energy.
Climate change is expanding Antarctica s sea ice, according to a scientific study in the journal Nature Geoscience.
The paradoxical phenomenon is thought to be caused by relatively cold plumes of fresh water derived from melting beneath the Antarctic ice shelves.
This melt water has a relatively low density, so it accumulates in the top layer of the ocean.
The cool surface waters then re-freeze more easily during Autumn and Winter.
This explains the observed peak in sea ice during these seasons, a team from the Royal Netherlands Meteorological Institute (KNMI) in De Bilt says in its
.
Climate scientists have been intrigued by observations that Antarctic sea ice shows a small but statistically significant expansion of about 1.9% per decade since 1985, while sea ice in the Arctic
