January this year was hottest January on record, NOAA says

Published

on


was the hottest January ever recorded in the 141 years agencies have been tracking the weather, scientists at the National Oceanic and Atmospheric Administration (NOAA) said on Thursday.


Last month also marked the 44th consecutive January and the 421st consecutive month with temperatures above the 20th-century average, NOAA said.

Temperatures in January were 1.14 degrees Celsius above the 20th-century average.

Arctic sea ice coverage was 5.3 per cent below the 1981–2010 average, while Northern Hemisphere snow coverage was below average as well.

“No land or ocean areas had record-cold January temperatures,” NOAA said.

The report will likely add to growing alarm over the state of climate change.

Scientists say sun has entered new 25yrs solar cycle

Published

on


Scientists say the sun has entered a new 25-year cycle and will enter a period marked by more sunspots and eruptions.


Experts from Germany’s Max Planck Institute for Solar System Research (MPS) made the announcement in a statement in Bremen on Wednesday.

The sun’s activity has been ramping up over the past nine months as it moves out of a minimum period of activity, experts said.

The sun alternates between 11-year periods of higher and lower activity, the scientists said, and the star passed its lowest point of activity in December 2019.

However, the next 25-year solar cycle is likely to be “just as tame” as the previous cycle, the institute predicted, with the most active period expected between November 2024 and March 2026.

What happens on the surface of the sun also affects the Earth.

“In phases of high activity, violent bursts of particles and radiation from the sun can also make themselves felt on Earth,” said MPS scientist Robert Cameron.

In the worst case, solar storms cause technical systems, such as satellites, to fail. Astronauts can also be harmed.

The new solar cycle is the 25th since reliable solar observations began.

For the past 30 years, the United States space agency NASA and the ocean and atmosphere agency NOAA have had a group of experts forecast solar activity for the coming years.

This is not easy because “our star’s behaviour is characterised by a peculiar interplay of reliability and capriciousness” MPS said.

US agency warns hurricane season this year could be one of the worst

Published

on


The Atlantic hurricane season has already set records this year, with nine named storms so far and up to 25 expected before November, when the season ends, according to the United States National Oceanic and Atmospheric Administration (NOAA).


Normally, there are only two named storms by this time of the year and the ninth generally does not form until October.

“This year, we expect more, stronger and longer-lived storms than average,’’ said Gerry Bell, NOAA’s top hurricane forecaster.

NOAA predicts that between three and six “major” hurricanes will hit the Atlantic region.

The agency has deemed this year to be an “extremely active” season and it is shaping up to potentially rival 2005, the busiest on record.

The eastern seaboard is currently dealing with Isaias, which at times has been a hurricane.

The storm has caused fatalities and left millions without power.

2020 World Hydrography Day: Navy to induct state-of-art offshore survey vessel

Published

on


As the world prepares to celebrate the World Hydrography Day, the Nigeria Navy ((NN) says that it will induct a state-of-the art offshore survey vessel with autonomous capabilities.


Rear Adm. Chukwuemeka Okafor, the Hydrographer of NN and the President, Nigerian Hydrographic Society said this in a statement on Sunday.

He also said that the Nigerian Navy Hydrographic Office (NNHO) was ready to provide up-to-date marine geo-spatial information on Nigerian waters to diverse maritime operators.

He said that the offshore survey vessel that would be unveiled next month would provide up-to-date marine geo-spatial information about the Nigerian waters to diverse maritime operators, for enhanced economic growth of the country.

Okafor said that the NNHO also was strengthening collaborations with developed hydrographic offices such as the National Oceanic and Atmospheric Administration (NOAA), United Kingdom Hydrographic Office (UKHO) and the French Hydrographic Office (SHOM).

” This is in order to tap from their experiences toward churning out new nautical products and solutions in the most internationally acceptable format,” he said.

Okafor recounting the NNHO’s achievements said that it had recently ramped up its hydrographic capabilities with several first-of-its-kind products to support Nigeria’s Blue Economy project.

“As you are aware, during the last WHD Celebration, the NNHO published the first indigenous navigational chart ever produced by Nigeria; NG 2501 (Lagos Harbour Chart) .

“This feat completed Nigeria’s hydrographic capacity development as required by the International Hydrographic Organisation (IHO).

“As at today, the Office has published the second edition of the chart, incorporating recent navigational significant changes that have taken place within the channel,” he said.

The Rear Admiral said that the office had also published the second indigenous navigation chart, NG 4401 (Ogunkobo to Tin Can Island)at the needed time due to the several marine accidents.

“The water within the area had hitherto never been charted and had recently witnessed several marine accidents.

He added that this achievement drew several commendations from top military echelons, the Federal Government and mariners who expressed delight to the usefulness of the chart to their voyages.

He also added that the country through the NNHO recently recorded another milestone in hydrographic capabilities, with the publication of Nigeria’s first Electronic Navigational Chart (ENC), NG525010.

He said that as the national charting authority in Nigeria, the NNHO also was collaborating with the Nigerian Hydrographic Society (NHS) on improving the standard of hydrographic practice, methods and technologies among private hydrographic practitioners.

He said that through it, Nigeria would be able to draw maximum benefits from the Crowd Sourced Bathymetric initiative of the IHO.

“This will go a long way to facilitate quicker survey and chart coverage of Nigerian water,” he said and ultimately place Nigeria on the right stead toward her actualising the Nippon Foundation/GEBCO seabed 2030 project.

He said that hydrography was a force multiplier to human survival and sustainability.

“If you look around you, almost everything you see; whether products or raw materials, is likely to have arrived the shores of Nigeria by ship.

“Ships, as we know, will be unable to safely sail from one place to another without accurate and up-to-date hydrographic information.

“Therefore, it is safe to say that hydrography is a force multiplier to human survival and sustainability,” he said.

Hottest global 5-year period in recorded history confirmed by Aussie scientists

Published

on


The last five years have been the hottest on earth since records began, Australia’s Climate Council has confirmed.


Data released by the Climate Council and the National Oceanic and Atmospheric Administration (NOAA) revealed that the global average temperature between 2013 and 2017 were the highest in any five-year period since global temperature has been tracked.

Will Steffen, a Climate Council scientist, said that 2017 was the third-warmest year on record and the warmest where temperatures were not boosted by an El Nino event in the southern Pacific.

The findings mean that 17 of world’s 18 warmest years have occurred this century.

“Temperatures and extreme weather records have toppled one after the other around the globe in 2017,” Steffen said in a media release on Friday.

“Australians have been touched by soaring temperatures, with some regions in New South Wales and South Australia experiencing daytime temperatures nearing 50 degrees (Celsius) last summer.

“Severe heat waves are silent killers, causing more deaths since the 1890s than bushfires, cyclones, earthquakes, floods and severe storms combined.”

The report was released as most of south-east Australia sweltered through a heat wave with Melbourne’s forecast maximum of 42 degrees Celsius on Friday; the hottest temperature the city has endured in two years.

The Climate Council also found that 260 low rainfall and high temperature records were broken in Australia’s winter of 2017 alone.

“Climate change is exacerbating extreme weather events across Australia and around the globe.

“This was obvious in 2017, from severe heat waves and bushfires, through to supercharged storms, cyclones and flooding,” Climate Council Chief Executive Officer, Amanda McKenzie, said.
