Australians Bury Heads in Sand to Mock Government Climate Stance



A group of around 400 demonstrators participate in a protest by burying their heads in the sand at Sydney's Bondi Beach November 13, 2014. Hundreds of protesters participated in the event, held ahead of Saturday's G20 summit in Brisbane, which was being promoted as a message to Australian Prime Minister Tony Abbott's government that, “You have your head in the sand on climate change”.

Antarctic sea ice could be thicker than thought, robot submarine finds





The floating sea ice surrounding the South Pole may be thicker than previous estimates have suggested, according to a study based on a submersible robot that has mapped the sea ice in three key regions of the Antarctic.

Past estimates of Antarctic sea ice were based on satellite measurements from space, which can measure its overall surface area, and ice cores drilled through the sea ice from ice-breaking ships to measure its thickness, which have tended to concentrate on thinner ice regions.

However, unlike the Arctic sea ice, there are no military submarines allowed under the Antarctic Treaty, which means that large regions of thicker sea ice have effectively remained unexplored from below, scientists said.

With the help of a 2m twin-hulled autonomous underwater vehicle, scientists from the United States, Australia and the British Antarctic Survey have drawn up the first detailed, high-resolution 3D map of Antarctic sea-ice in areas that were in the past considered too difficult to study.

“The AUV missions have given us a real insight into the nature of Antarctic sea ice, like looking through a microscope. We can now measure ice in far greater detail and were excited to measure ice up to 17m thick,” said Jeremy Wilkinson of the BAS.

“It gave us a really good basis for what the ice thickness is at present. Over time we hope to make repeat measurements and build up a time series to see how it is changing,” Dr Wilkinson said.

The robotic submersible used upward-looking sonar to map the thickness of the sea ice over an area of 500,000 square miles equivalent to about 100 football pitches, in three locations – the Weddell, Bellinghausen and Wilkes Land sectors of Antarctica.

While the sea ice in the Artic has decreased in surface area by about 40 per cent over the past 40 years, the sea ice in the Antarctic has increased for reasons that are still under debate. Dr Wilkinson said that one cause could be a change in wind patterns that is blowing sea ice further out to sea.

human are doing bad for the environment i agree.
but earth survived billions of years survived geographic changes, cosmic radiations, volcano, earth quakes even more intense stuff.
the modern form of humans only evolved about 200,000 years ago. Civilization as we know it is only about 6,000 years old, and industrialization started in the earnest only in the 1800s.

earth will survive and found its way, human can reduce the damage yes but can never really do any damage.

Costa Rica goes 75 days powering itself using only renewable energy

Costa Rica has achieved a clean energy milestone by using 100 per cent renewable energy for a record 75 days in a row.

The feat was achieved thanks to heavy rainfall, which powered four hydroelectric plants in the first three months of the year, the state-run Costa Rican Electricity Institute said.

No fossil fuels have been burnt to generate electricity since December 2014, in the state which is renowned for its clean energy policies.

While Costa Rica is a small country, with a popular of about 4.8 million people, it has made great strides in its use of renewable energy.

Last year 80 per cent of the energy used came from hydropower, while geothermal energy made up about 10 per cent of the mix in the volcano-strewn nation.

Currently 94 per cent of Costa Rica’s energy needs are met by renewables.

New geothermal projects are already in the planning stages, to ensure that the Central American state does not have to rely on fossil fuels in the future.

The government approved a US$958 million geothermal project in mid-2014.

The first plant, when completed, is expected to produce 55 megawatts of electricity, enough to power 55,000 homes. A further two 50 megawatt plants will be built nearby.

Jake Richardson, of Clean Technica, said it was important the country did not become too dependent on hydropower.

“It’s good news that more geothermal will be coming on board, as there are obvious downsides of being too reliant on hydropower, especially run-of-the-river systems, which can be hindered by seasonal changes in water flow,” he told Science Alert.

“Droughts can also severely impact power supplies. And there are also some environmental downsides to hydroelectric dams more generally, namely the impact on riparian ecosystems and passing fish.”

It helps that Costa Rica, which aims to be carbon-neutral by 2021, has excellent infrastructure.

The World Economic Forum ranked the country second in Latin America, behind Uruguay, for its electricity and telecommunications infrastructure in its 2014 Global Competitiveness Index.

In a sign of how committed Costa Rica is to renewables the government has decided not to exploit rich oil deposits - discovered along the country’s Caribbean coast - for environmental reasons.

‘Slow-down’ in climate change never happened, says major review

A major review of global temperatures by a leading US Government agency has failed to find support for the view that global warming has slowed down since 1998, as many climate sceptics have repeatedly claimed over the past two decades.

The prestigious US National Oceanographic and Atmospheric Administration (NOAA) has re-evaluated its surface temperature records over land and sea and concluded that the rate of global warming has been just as fast at the start of this century as it was at the end of the last.

NOAA scientists believe that the global warming “hiatus” highlighted in the last report of the UN’s Intergovernmental Panel on Climate Change (IPCC) – and exploited by sceptics to undermine climate change policy – is nothing more than an illusion resulting from artefacts in the data.





In a study published in the journal Science, the scientists said that previous measurements of surface temperatures on land and sea have under-estimated the rate of warming over the past 15 years or so. When the figures are properly calibrated it becomes clear that the warming has continued as fast or even faster than before, the scientists said.

“These results do not support the notion of a ‘slowdown’ in the increase of global surface temperatures,” says the NOAA study, led by Thomas Karl, director of the US National Climate Data Centre, which runs the largest climate archive in the world.

Climate sceptics such as former Chancellor Lord Lawson and ex-minister Peter Lilley have repeatedly claimed that global warming has either stopped or slowed down. Even the IPCC’s last report two years ago said that average global surface temperature “has shown a much smaller increased linear trend over the past 15 years than over the past 30 to 60 years”.

However, the NOAA study reviewed the way measurements have been collected for sea-surface temperatures over the decades, as well as including fresh data for land-surface temperatures, and concluded that the IPCC’s statement “is no longer valid”.

Jay Lawrimore, a NOAA scientist and co-author of the study, said the improvements in temperature recording and analysis, and the fact that the Arctic is under-represented in the dataset even though the region is known to be warming much faster than the global average, means that, if anything, the latest calculation of the rate of global warming is an underestimate.

“It’s clear there is no hiatus and temperatures are continuing to warm – 2014 was a record warm year and we expect 2015 to be if not the warmest, then close to it. The evidence we see is that temperatures are continuing to rise,” Dr Lawrimore said.

“We are likely to be under-estimating the true trend in warming because we’re not including the Arctic. If we did, then we’d probably get even higher warming trends,” he told The Independent.

The study found that between 2000 and 2014, average global surface temperatures increased at a rate of 0.116C per decade, compared to 0.113C per decade between 1950 and 1999. “There is no discernible (statistical or otherwise) decrease in the rate of warming between the second half of the 20th Century and the first 15 years of the 21st Century,” the study’s authors concluded.

Changes in the way sea-surface temperatures have been collected over the decades, with a shift away from recording temperatures in water drawn by buckets or the cooling intakes of ships’ engines to measurements from floating buoys, meant that the data had to be better calibrated, NOAA said.

The increasing number of weather stations recording surface temperatures over land has also lead to the need to correct inherent biases. But even so, the lack of surface temperatures recordings in the Arctic will inevitably mean that the global coverage is incomplete and the true rate of global warming is likely to be even greater than its published estimates, NOAA said.

“This reassessment of global temperatures, which gives that there has been no pause or slowdown in surface warming since 1998, is very important as it comes from an extremely well regarded group at a US Government laboratory,” said Professor Sir Brian Hoskins, a distinguished British meteorologist and chair of the Grantham Institute at Imperial College London.

However, other scientists pointed out that NOAA is one of four independent organisations gathering and analysing global temperatures, and other groups have detected a slight slowdown in the rate of global warming, which is why the IPCC report mentioned a “hiatus”.

“This new study suggests that the slowdown in the rate of warming may be much less pronounced than in the global temperature records that were available for the IPCC to assess,” said Professor Tim Osborn of the University of East Anglia, which handles the British temperature dataset with the Met Office Hadley Centre.



“The IPCC’s assessment wasn’t wrong, but perhaps the emphasis would be slightly different if the assessments were carried out afresh with the new studies since 2013 that could now be considered,” Professor Osborn said.

“I would caution against dismissing the slowdown in surface warming on the basis of this study….There are other datasets that still support a slowdown over some recent period of time, and there are intriguing geographical patterns such as cooling in large parts of the Pacific Ocean that were used to support explanations for the warming slowdown,” he added.

UK and US main barriers to addressing climate change, survey finds

They're the two biggest emitters of greenhouses gases in the world — but the US and China have very different ideas about tackling the problem of climate change.

In a new survey taken months before officials meet for perhaps the most significant climate change talks ever held, YouGov found that people the US and UK lag far behind countries including China in wanting those talks to produce a meaningful commitment to address climate change.

In December, international representatives will meet in Paris to discuss an international agreement that some think could be humanity's last chance to limit the terrible effects climate change could have on the world and its population. But much of the US and the UK don't want their governments to do anything at all.

In the US, 17 per cent of people “do not agree to any international agreement that addresses climate change”. That number is 7 per cent in the UK.

In China and Indonesia, on the other hand, it is only 1 per cent. In China, 60 per cent of people want their representatives to “play a leadership role in setting ambitious targets to address climate change as quickly as possible” — in the UK, that number is 41 per cent.



Reluctance in the UK and US for officials to address climate change might be a result of the belief among many that there is no problem at all. Asked "how serious a problem, if at all", it was, 32 per cent of people said either not at all or not very.



Part of China’s concern about climate change will be provoked by how clear its effects have been. Recently urban areas have been hit by huge air pollution, increasing the awareness of climate change among the population.

But those differences are likely to change the way that the negotiations in December are handled, as well as how their results are seen. Around the world most people want their governments to set ambitious targets and so could end up disappointing if the climate change talks fall through.

But given the unwillingness of people in the UK and US — major polluters, as well as international powers — to ask for similarly ambitious targets, talks could be held back. “Despite some lingering doubts, particularly in the US, a failure to reach an agreement in Paris would likely be met with disappointment throughout much of the world,” YouGov notes.

YouGov’s data was based on surveys conducted between May 22 and May 27. The company noted that in China all questions were taken online, which could have affected the results.

Thousands of people killed by extreme weather so far in 2015 as climate change feared to bring more heatwaves, hurricanes and floods in future

Thousands of people have been killed by extreme weather so far this year amid fears that climate change is leading to more deadly heatwaves, floods, hurricanes and tornadoes.

More than 1,000 people have died in Pakistan this week of heatstroke and dehydration as temperatures soared far above 40C and power cuts crippled Karachi.

India is currently recovering from the second deadliest heatwave in the country's history, which had killed 2,500 people by the start of this month.



The Earth Sciences Minister, Harsh Vardhan, blamed the heatwave on climate change.

“Let us not fool ourselves that there is no connection between the unusual number of deaths from the ongoing heat wave and the certainty of another failed monsoon,” he said.

“It's not just an unusually hot summer, it is climate change.”

Scientists at Oxford University have started work on a scientific model they hope will enable them to establish or rule out links between climate change and extreme weather more quickly.

It typically takes about a year to determine whether human-induced global warming played a role in a drought, storm, torrential downpour or heatwave, allowing sceptics to dismiss the impact in the immediate aftermath of disasters.

“We want to clear up the huge amounts of confusion around how climate change is influencing the weather, in both directions,” Dr Friederike Otto, of Oxford University’s Environmental Change Institute, told The Independent in October.

She said global warming probably contributed to 2013’s record heat in Australia and last year’s flooding in the UK.

Australian scientists have also warned of a “substantial” El Nino effect that could bring droughts and flooding later this year.

The phenomenon, which arises from variations in ocean temperatures, is still in its early stages but has the potential to cause extreme weather around the world, according to the Bureau of Meteorology.

Here are some examples of extreme weather around the world so far this year:

Heatwaves



More than 1,000 people have now been killed in Pakistan’s continuing heatwave as the deadly temperatures look set to continue.

Karachi, the county’s largest city, has also been hit by huge power cuts leaving more than 20 million people struggling to cool their homes.

Officials said about 40,000 people have suffered heatstroke since Saturday and the number was expected to rise.

It is the worst heatwave in Karachi for more than 35 years, seeing morgues run out of space for bodies and emergency clinics set up in the streets.

People are being urged to look out for the signs of heat exhaustion, which can develop into potentially deadly heatstroke that causes the body to shut down as its temperature rises beyond safe levels.

The deaths in Pakistan come after last month’s heatwave in India, which had killed 2,500 people by the start of June.

Several areas in South America, the Caribbean, the US, Asia and Africa are also suffering droughts related to unusually high temperatures and a lack of rain.

Floods



More than 400 people are believed to have died in flooding so far this year.

In January, the Southeast Africa Floods, which were partly caused by a tropical storm, killed at least 176 people in Malawi, 86 in Mozambique and 46 in Madagascar in just a week.

More than 250,000 people were forced to leave their homes, the United Nations said, and hundreds more people were missing.

Later that month a teenage girl died in Malaysia after floods hit parts of Sarawak and Sabah.

Another deluge hit Tanzania in March, killing 38 people and wounding dozens more.

Devastating floods in northern Chile left at least 25 people dead in the same month and officials feared that number would rise with 125 people still missing in April. More than 30,000 people were affected.

A huge storm front that moved through Texas and Oklahoma at the end of May triggered record-breaking rainfall and spawned several tornadoes.

The deaths of 27 people were attributed to flooding in Texas, four in Oklahoma and 11 people were missing.



Then at the start of this month, Accra, the largest city in Ghana, was hit by days of downpours that flooded markets and trapped workers.

At least 25 people were reported to have died as a direct result of the flooding but it caused a huge explosion at a petrol station that killed 200 more.

Last week, torrential rain turned the river running through the Georgian capital of Tbilisi and killed 19 people. Another man was also mauled to death by a tiger that escaped the city’s zoo when its enclosure was destroyed.

Flash floods brought the Black Sea resort of Sochi to a standstill today, halting trains and leaving cars half-submerged in the city where Russia staged the Winter Olympics.

There have not yet been any reports of casualties.

Tornadoes



Almost 500 people are estimated to have been killed by tornadoes so far this year, mostly in China.

A half-mile wide F1 twister that passed over the Yangtze River on 1 June reportedly caused a cruise ship to capsize and sink, killing more than 440 out of 454 people on board.

Other deadly tornadoes struck in Mexico, Burma, Brazil and the US.

An outbreak that hit Texas, Oklahoma and Mexico between 24 and 26 May killed 15 people, mostly in Mexico, and the storm front also unleashed deadly floods.

Tornadoes form all over the world, including in the UK, but are usually most destructive in the US, parts of India and Bangladesh.

Cyclones and hurricanes



Fewer than 100 deaths have been recorded due to hurricanes and cyclones this year, but the toll is feared to rise as the storm season starts in the Atlantic.

Pacific typhoons, which started forming in January, have so far killed an estimated 25 people in four separate storms that struck the Philippines, Carline Islands, Marshall Islands, Mariana Islands, Taiwan, Japan, Vietnam, China, Laos and Thailand.

The “monster” cyclone that hammered a tiny South Pacific archipelago in March was caused by climate change, it was claimed.

At least 60 deaths were also attributed to two storms this month that struck Odisha, Gujarat and Maharashtra during the North Indian Ocean cyclone season.

One person died in Mexico during Hurricane Carlos earlier this month, when they were reportedly hit by a falling piece of metal during high winds.

It was unclear whether deaths attributed to the storms were caused by wind, debris, floods or other factors.

The Atlantic hurricane system started at the beginning of this month and has not yet spawned any severe storms, which are expected until the end of November.

'Mini ice age' coming in next fifteen years, new model of the Sun's cycle shows

There will be a "mini ice age" in 2030, solar scientists have said.

We are now able to predict solar cycles with far greater accuracy than ever before thanks to a new model which shows irregularities in the sun’s 11-year heartbeat.

The model shows that solar activity will fall by 60 per cent between 2030 and 2040 causing a "mini ice age".

The conditions predicted have not been experienced since the last "mini ice age" which lasted from 1645 to 1715, called the Maunder Minimum.

The findings are being presented by Professor Valentina Zharkova at the National Astronomy Meeting in Llandudno.

In 1843 scientists first discovered that the sun's activity varies over a cycle of 10 to 12 years.

Fluctuations within that cycle have been difficult to predict, although many solar physicists new that the variations were caused by a dynamo of moving fluid deep inside the sun.

Professor Zharkova’s team of researchers has found that adding a second dynamo close to the surface of the sun, creates a far more accurate model.

The scientists found magnetic waves in two different layers of the sun’s interior which fluctuate between the northern and southern hemispheres of the sun.

“Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97 per cent," Professor Zharkova said.

The magnetic wave patterns show that there will be fewer sunspots in the next two solar cycles. Cycle 25, which peaks in 2022 and Cycle 26, from 2030 to 2040 will both have a significant reduction in solar activity.

What is Global Warming?

Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent.


Over the last 100 years, the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C, or 1.3 ± 0.32° Fahrenheit). Does not seem all that much? It is responsible for the conspicuous increase in storms, floods and raging forest fires we have seen in the last ten years, though, say scientists.



Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years. Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last eight years, even.


--------------------------

I ve never thought about that as a problem till now, i got a child shes 8 days old,i m thinking would she see good days whould she live to see her children.......?
Do our governor Pm president and mayor all of them thought about that i dont think so.I m Sure they are thinking about how to burn some more forest this summer to SELL 7atab next winter.
Believe me guys i m not expecting anything from those who stole us and still steeling us else money and money and money talk.
Wish we can do smthg about that b4 its too late

I wished Ghassan Rahbani made it ,Hope (L ta3en) bring him back..






Global warming now a day is man made, do you know that the earth has the ability to heal itself?
