Global SO2 emissions dropped last year according to new report

October 8, 2020 Leave a Comment

Anthropogenic sulfur dioxide (SO2) emissions fell globally in 2019, reveals a new analysis of NASA satellite data by Greenpeace India and the Centre for Research on Energy and Clean Air (CREA). In 2019 human-made SO2 emissions fell in all three of the world’s top SO2 emitter countries - India, Russia and China - the report shows. "While heartening at first glance, the drop … [Read more...]

Mpumalanga a hotspot for deadly sulphur dioxide emissions

August 19, 2019 Leave a Comment

NASA satellites have found the Kriel area in Mpumalanga to be a global hotspot for deadly sulphur dioxide (SO2) emissions. A new study commissioned by Greenpeace India used NASA estimates of anthropogenic sulfur dioxide (SO2) emissions from hotspots around the world, based on data from the agency's satellites. The study found that Kriel in Mpumalanga, with its high … [Read more...]

Bluefin tuna on the brink of extinction

August 15, 2017 Leave a Comment

Pacific bluefin tuna has unique worldwide status as one of the most awe-inspiring remarkable creatures on the planet. They grow to 12 feet and 1,500 pounds and live up to 35 years whilst swimming super-fast, crossing the entire ocean in 21 days. They are the essence of nature’s wonderful creativity and beauty. Unequivocally, the bluefin’s days are numbered, almost guaranteed … [Read more...]

Combined Arctic ice observations show decades of loss

August 11, 2016 Leave a Comment

It’s no surprise that Arctic sea ice is thinning. What is new is just how long, how steadily, and how much it has declined. University of Washington researchers compiled modern and historic measurements to get a full picture of how Arctic sea ice thickness has changed. The results, published in The Cryosphere, show a thinning in the central Arctic Ocean of 65 percent between … [Read more...]

Arctic sea ice reaches lowest annual maximum on record

April 17, 2015 Leave a Comment

This year's maximum Arctic sea ice extent was the lowest in the satellite record and occurred 15 days earlier than the average date for the period from 1981 to 2010, reported NASA and NSIDC. The sea ice cap of the Arctic appeared to reach its annual maximum winter extent on Feb. 25, according to data from the NASA-supported National Snow and Ice Data Center (NSIDC) at the … [Read more...]

First three months of 2015 were warmest on record

April 17, 2015 Leave a Comment

March this year was the third hottest month in global climate records, according to reports from NASA GISS. The reading — at +0.84 C above the 20th Century average — fell just behind March of 2002 (+0.88 C) and March of 2010 (+0.87 C). With El Nino firing off in the Pacific and polar amplification pushing to ever-greater extremes in the Arctic, 2015 is following hot on the … [Read more...]

CO2 emissions may help tropical rainforests grow faster

January 14, 2015 Leave a Comment

A new NASA-led study shows that tropical forests may be absorbing far more carbon dioxide than many scientists thought, in response to rising atmospheric levels of the greenhouse gas. The study estimates that tropical forests absorb 1.4 billion metric tons of carbon dioxide out of a total global absorption of 2.5 billion -- more than is absorbed by forests in Canada, Siberia … [Read more...]

Image series shows ozone hole development since 1979

September 17, 2014 Leave a Comment

The stratospheric ozone layer protects life on Earth by absorbing ultraviolet light, which damages DNA in plants and animals (including humans) and leads to skin cancer. Prior to 1979, scientists had not observed concentrations below 220 Dobson Units. But in the early 1980s, through a combination of ground-based and satellite measurements, scientists began to realize that … [Read more...]

NASA launches carbon tracking satellite

The ability of scientists to make accurate predictions about future effects of CO2 will be boosted by vital data from a new US satellite sent to take a detailed inventory of the planet’s sinks and sources of carbon. The US space agency NASA sent up a satellite on 2 June, which will provide vital data for predicting future effects of CO2by taking the measure of the planetary … [Read more...]

To live to love seems the best way forward

April 21, 2014 Leave a Comment

Tomorrow, 22 April, we celebrate Earth Day across the globe. Reverberating from the shocks of the latest IPCC report, as well as the NASA scientists’ report we shared recently, I am faced with a moral dilemma. What is now the best course of action? Try to push back the floods of destruction that seem daily more inevitable, or accept that our modern civilisation is not … [Read more...]

what-makes-northern-lights-happen?

One of the most stunning natural events our atmosphere offers us is the Aurora Borealis, or Northern Lights. Waves of color dance across the sky during the night, displaying different colors and patterns. But what makes this happen? The answer is an interesting combination of solar wind, magnetic fields, electrical currents, and at least one person standing around to go, … [Read more...]

Africa: On fire from space

December 12, 2011 Leave a Comment

africa-on-fire-from-space

30% of the earth’s surface is affected by fire. Fire destroys forests and vegetations which are our sources of food – it is both a driver and an indicator of climate change. When biomass is burned, copious amounts of gases and particulate matter are released, billowing smoke plumes fill the sky, and entire ecosystems can change in seconds. “We’ve seen very saddening … [Read more...]
