Climate Change and Groundwater
Climate change may be creating a groundwater “time bomb” as the world’s underground water systems catch up to the impacts of global warming.
Researchers for a study published Monday in the journal Nature Climate Change say more than half of the world’s groundwater systems — the largest source of usable freshwater in the world — could take more than 100 years to completely respond to current environmental changes from global warming.
Groundwater is replenished primarily by rainfall through a process known as recharge. Concurrently, water exits or discharges from groundwater sources into lakes, streams and oceans to maintain an overall balance.
When there is a change in recharge due to a lack of rainfall, for example, levels of groundwater drop until balance is restored.
Groundwater systems take a lot longer to respond to climate change than surface water, with only half of the world’s groundwater flows responding fully within ‘human’ timescales of 100 years. This could be described as an environmental time bomb because any climate change impacts on recharge occurring now, will only fully impact the base flow to rivers and wetlands a long time later.
Wildfires – Tasmania
Bushfires in the Australian state of Tasmania endangered houses and property on Wednesday, with visitors urged to be cautious before setting off.
Around 50 blazes have erupted across the state with emergency alerts set off for six areas in the central region and authorities declaring that one house has already been burnt.
Teams have been in efforts to put out the fires for much of the summer, including a huge burn near the Gell River which has so far burned more than 20,000 hectares of wilderness.
Ebola – DR Congo

The 14 new confirmed cases include 9 in Katwa, 2 in Mangurujipa, 1 in Biena, 1 in Butembo and 1 in Kayina. In addition, there were 439 total deaths.
Measles – Ukraine
In a follow-up on the measles epidemic in Ukraine, health officials report an additional 3,450 cases (1,502 adults and 1,948 children) during the third week of 2019, bringing the total to 8,498 cases to date. In addition, three additional measles fatalities were reported last week, bring the death count to five.
Legionnaires Disease – Sydney, Australia
Sydney building owners have been warned to guard against legionnaires disease outbreaks by checking their water cooling towers, after four people contracted the condition.
Global Volcanic Activity – Volcanoes Today, 24 January 2019
Shiveluch (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 and is moving at 25 kts in SW direction.
Manam (Papua New Guinea): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140.
Dukono (Halmahera): Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: CONTINUOUS VA TO FL070 LAST OBS AT 23/0700 EXT E
Popocatépetl (Central Mexico): The volcano has been particularly active recently. A series of very strong explosions occurred on Tuesday (22 Jan 2019) which destroyed the most recent lava dome that had accumulated in the summit crater. The strongest was a powerful vulcanian-type eruption at 21:07 local time, which ejected incandescent material to more than 2 km height and distance from the crater and produced an ash plume that rose approx. 4 km above the summit. The ejecta showered the entire upper cone of the volcano with glowing bombs, in up to 2 km distance.
Fuego (Guatemala): Volcanic Ash Advisory Center Washington (VAAC) issued the following report: NEW VA CLD
Sabancaya (Peru): Volcanic Ash Advisory Center Buenos Aires (VAAC) issued the following report: SPORADIC PUFFS OF VA.
Planchón-Peteroa (Central Chile and Argentina): Volcanic Ash Advisory Center Buenos Aires (VAAC) issued the following report: continuous ash emissions.
