I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Multiphase buffering by ammonia explains wide range of atmospheric aerosol acidity” Multiphase buffering effect of emitted ammonia controls aerosol pH, thereby influencing the haze chemistry and formation of aerosol particles, especially nitrate, sulfate and ammonium. It shows a close link between the nitrogen cycle and atmospheric chemistry. The picture shows a hazy day in Guangzhou,…
“#High-fidelity record of Earth’s climate history puts current changes in context” Past and future trends in global mean temperature spanning the last 67 million years. Oxygen isotope values in deep-sea benthic foraminifera from sediment cores are a measure of global temperature and ice volume. Temperature is relative to the 1961-1990 global mean. Data from ice…
“#Historical climate fluctuations in Central Europe overestimated due to tree ring analysis” Credit: CC0 Public Domain “Was there a warm period in the Middle Ages that at least comes close to today’s? Answers to such fundamental questions are largely sought from tree ring data,” explains lead author Josef Ludescher of the Potsdam Institute for Climate…
“#Consequences of the 2018 summer drought” The Bioclimatology Group of the Faculty of Forest Sciences and Forest Ecology at the University of Göttingen is part of the ICOS European Research Infrastructure network with a meteorological station in the Hainich National Park.

“#New insight on the impacts of Earth’s biosphere on air quality” Credit: CC0 Public Domain A new study led by a team of University of Minnesota researchers provides the first global satellite measurements of one of the most important chemicals affecting Earth’s atmosphere. Isoprene is a natural hydrocarbon emitted to the atmosphere in vast quantities—approximately…
“#As another heat wave sears California, experts say health impacts will worsen with climate change” Credit: CC0 Public Domain As the second major heat wave in weeks bears down on Southern California, experts and authorities are warning the public to take seriously the health dangers of extreme temperatures that are only getting worse due to…
“#Fire, smoke, heat, drought: How climate change could spoil your next glass of California Cabernet” Credit: CC0 Public Domain A couple of years ago my wife and I visited the Bonny Doon Vineyard near Santa Cruz to sample the offerings of winemaking savant Randall Grahm. While we were there, Grahm told us something I haven’t…
“#Mojave Desert fire in August destroyed the heart of a beloved Joshua tree forest” Credit: CC0 Public Domain The first day of California’s lightning siege, thunderstorms rolled across the Mojave National Preserve, slicing the afternoon sky with dry strikes. Smoke rose from the top of Cima Dome, marking the start of a wildfire that would…
“#Extreme heat made August the fourth-warmest on record worldwide” Credit: CC0 Public Domain August 2020 will go down as the fourth-warmest on record worldwide, with above average summertime heat in the U.S. and Mexico tempered slightly by below average temperatures in parts of the Southern Hemisphere. Global temperatures for the month spiked around 0.9 degrees…
“#Study analyzes the impact of carbon dioxide on Earth’s climate 30 million years ago” Researchers calculated how atmospheric CO2 evolved studying fossil shells of ancient marine plankton. Credit: University of Southampton One way to make better predictions of global warming in the coming centuries is to look at climate change in the geological past. In…
