Global Warming

Global warming could stave off next ice age for 100,000 years

Global warming is likely to disrupt a natural cycle of ice ages and contribute to delaying the onset of the next big freeze until about 100,000 years from now, scientists have suggested.

In the past million years, the world has had about 10 glacial periods before swinging back to warmer conditions like the present.

In the last glacial period known as the Ice Age, which ended 12,000 years ago, ice sheets blanketed what is now Canada, northern Europe and Siberia.

In a new explanation for the long-lasting plunges in global temperatures that cause ice ages, scientists pointed to a combination of long-term shifts in the Earth’s orbit around the sun, together with levels of carbon dioxide in the atmosphere.

They said the planet seemed naturally on track to escape an ice age for the next 50,000 years, an unusually long period of warmth, according to the study led by the Potsdam Institute for Climate Impact Research and published in the journal Nature.

But rising man-made greenhouse gas emissions since the Industrial Revolution began in the 18th century could mean the balmy period will last for 100,000 years.

The findings suggest human influences “will make the initiation of the next ice age impossible over a time period comparable to the duration of previous glacial cycles”.

Earth’s orbit around the sun is oval in shape but this becomes more circular every 100,000 years and more particularly so every 400,000 years.

Disease

Ebola – West Africa

The Ebola outbreak in West Africa is not over quite yet — just one day after the region was declared “Ebola-free,” a new case of the virus was confirmed in Sierra Leone. WHO had said such flare-ups were to be expected.

Zika virus infection – France – Overseas Departments

On 21 December 2015, WHO received notification of the first 2 laboratory-confirmed cases of Zika virus infection in two overseas departments of France: Remire-Montjoly, French Guiana and Schœlcher, Martinique. Since then, 2 additional cases have been reported in Saint Laurent du Maroni, French Guiana and in Fort de France, Martinique.

Foot and Mouth Disease in Malawi

Malawi Government has suspended all livestock sales in Nsanje district following the outbreak of foot and mouth disease in the district.

The Ministry of Agriculture, Irrigation and Water Development through its secretary Bright Kumwembe says there is an outbreak of the disease in cattle at Bangula dip tank and Magoli Extension Planning Area (EPA) in the district which is within the Shire Valley ADD.

Preliminary investigation conducted by veterinary field staff from the Shire Valley ADD and Department of Animal Health and Livestock Development indicates a total number of 60 critical cases out of a total of 581 cattle in 4 kraals.

The ministry further said a total of 65,000 cattle are at risk within the affected area and investigations are ongoing to establish the extent of the problem.

Volcanos

Roundup of Global Volcanic Activity

San Miguel (El Salvador): The volcano continues to show strong degassing with light ash content, generating a plume that rises up to 1500 m from the crater and is being blown westwards. Tremor amplitude remains elevated.
