Arctic sea ice melt at record level


Recommended Posts

More sea ice has melted in the Arctic this summer than at any time since satellite records began more than 30 years ago, scientists say.

It is thought a natural warming and cooling cycle could be responsible for up to 30% of the melting - but the rest is the result of human activity releasing greenhouse gases.

Roger Harrabin reports.

And deniers say , there has not been any increase in warming or Arctic ice for a few years :rofl: .

This is just natural for the Earth to do.. right.. right!?

I kid but it's a sad state of affairs..

The problem is is that there's no proof to show whether greenhouse gases are causing the arctic to melt.

My thoughts are that it's much more probable that the sun's cycle and nature has more to do with it.

Regardless, we just don't have enough data to show any sort of reliable trend.

I believe that its Co2 but your right nobody really knows , but we should stop going business as usual just in case its Co2

I think the proof is all around us an a majority of scientists certainly agree to the idea of climate change. We've seen an increasing number of droughts, forest fires and freaky weather including soaring temperatures.

There's also a large agreement in most of the worlds scientific bodies that global warming is happening and by and large man-made.

Of all the greenhouse gasses being put into the Ozone, Mankinds contribution makes up a tiny percentage. We get hugely outclassed by Bovine Methane Emissions (Methane is 100x better at being a greenhouse gas than CO2) and Volcanos. Most of what decides the planets temperate depends on the output of the Sun anyway, and that fluctuates wildly.

That's not really true though when Methane is said to be around 20 times more powerful than CO2 and cows amount to around 3% of Britain's overall greenhouse gas emissions...

I agree that the weather has been interesting over the past 10-20 years or so. I remember as a kid having crazy winters with multiple feet of snow at a time, and now in recent years, we have been lucky to not have a green Christmas. Through 2 years ago we had an absolutely terrible winter, so it was a bit of a combo-breaker.

But overall, who's to say that it's not just the tip of a 100 year cycle or something? Maybe we'll start to have less natural disasters and more regular-defined seasons as the cycle recedes or starts over. Once and a while you'll hear about some temperature record from 1893 or whatever that was broken, but then you have to consider that those temperatures occurred back then as well, so it really isn't so out-of-the-ordinary. All it will take is a 5-10 year stretch of more "normal" or "better than normal" weather and the whole "global warming" theory will be brought to it's knees.

The increased road tax on high emissions vehicles has worked then. Putting people out of pocket for a good cause and all that.

Given that cows are bred for human consumption are you claiming that their emissions shouldn't be counted as man-made? If their emissions are such a concern then we should switch to more environmentally friendly food sources. As for whether the majority of CO2 is man-made or not, that can be determined by examining the balance between carbon-13 and carbon-14 isotopes. As you will see here, CO2 production from human activities (30 billion tons) is 130 times greater than that from volcanoes (145-255 million tons). As always, before you repeat an opinion you heard elsewhere it is always worthwhile to verify it.

The idea that anthropogenic climate change is disputed in the scientific community is simply wrong.

I don't think that global warming is really a theory anymore considering the science has shown that temperature has increased from around the 1850's. I wouldn't consider you having a terrible winter proves that the temperature is dropping globally though...

Also read that's thought that a volcanic eruption only effects the atmosphere surrounding it for around 2 years.

it was perfect balance of co2 released and consumed by plants , we came around produced more co2 and chopped down the plants.

That is true , Joe public believes if there is a bit of snow on the ground global warming and climate change is not happening.

They don't seam to realise that there is a world outside there house.

Who says it was a perfect balance? The levels of CO2 aren't what drives plant growth.

Oh, I know. I'm just in a small insignificant area compared to the rest of the world, but my point was that there are cycles that occur all the time in nature. Hurricane cycles, seasonal cycles, etc etc. I just find it hard to believe that the climate change isn't some sort of cycle that simply has a longer duration than we have been currently able to measure.

I just don't think we should limit our progress as a civilization quite yet because a few people think we are killing the Earth.

A few people? Like I said it's largely agreed upon now and certainly is in the scientific community. In fact all the scientific papers published between 1993 and 2003 that held the idea of man-made climate change was rejected. it's believed that 97-98% of climate experts worldwide agree on man-made warming.

I wouldn't consider the dirty factories in China or the US to be furthering the progress of civilization at the cost of the Earth. I'd say that researching and developing ways to limit humanities impact on the climate with greener, better ways would be huge progress for civilization, not the belching factories of the world.

hurry up and put all the co2 and methane in the atmosphere so it can drop temperatures ... I HATE summer ... hate the heat and the damn smell and smog/stickiness and you feel as dirty as just before/after you take a shower.

Winter!!!! sooooooo much better ... every time you look at the snow fakes you instantly become happier .. take a sled or through some snowballs ... do some 180degrees with the car ... and then some warm beverages ... either warm wine with some spices or whatever floats your boat ....

so everyone .. go buy a hummer and lets do this .... for a good cause !!!!!

Actually. that's pretty much the exact opposite of what you want.

What you suggest, will result in shorter/less snowy winters.

I was thinking something like this :

more CO2/Gasses makes the ice melt --> fresh water into ocean will destroy the "conveyor" (the water stream that flows beneath/through the oceans .. that will upset the nature into a similar "The Day after Tomorrow" scenario where nature re-acclimates itself .. then again, not a scientist and Hollywood messed up my senses so I could be 101% wrong ....

also ...

if the sun melts ice,

temp increase,

water evaporates,

water droplets increase temp (lensing effect),

more dust , dust covers sky ,

people start nuking themselves,

clouds decrease temp,

most stupid dies

lower temp

....

win! :) ... goto say, slow day at work, bored, tired and sleepy ... never the less, genius idea ... goto put it as a theory of inevitability !!! .. yes!

---had to edit, really bored ....

as long as we are dependent on fossil fuels and the economy and society demands it the effect will be present more pronounced as compared to natural occurrences

      UK's Met Office and Microsoft sign supercomputer deal
      by Paul Hill



      Microsoft has announced that it has signed a multimillion-pound agreement with the Met Office – the UK government’s meteorological service – for the provisioning of a new supercomputer that will improve weather and climate forecasting.

      According to Microsoft, the new supercomputer will be in the top 25 supercomputers worldwide and will be twice as powerful as any of the other supercomputers in the UK. As the planet continues to heat up, the new supercomputer will be able to help the country prepare for the more severe storms, floods, and snow that is expected in the coming years.

      Commenting on the agreement, Penny Endersby, Chief Executive of the Met Office, said:

      Microsoft and the Met Office plan to have the new supercomputer up and running sometime in the summer of 2022. Over the 10-year lifespan of the agreement, financial benefits are expected to reach up to £13 billion.

      As with all supercomputers, this one will be energy-intensive. Microsoft said that it will be powered by 100% renewable energy and will take advantage of energy efficiency methods. It’s expected that these efforts will save 7,415 tonnes of CO2 in the first year of operational service alone.

      China's bitcoin mining empire is at odds with the country's pledge to go carbon-neutral
      by Ather Fawaz



      Researchers from Tsinghua University and the Chinese Academy of Sciences have said that China's power-hungry bitcoin mining empire could undermine the country's pledge to peak carbon emissions by 2030 and eventually go carbon neutral by 2060. The study, published Tuesday in Nature Communications, says that close to 40% of China's bitcoin mines are powered by coal and will produce 130.5 million metric tons of carbon emissions by 2024.

      Bitcoin, after growing fivefold in the past year alone, eclipsed the $50,000 threshold in February and reached a record high of over $61,000 in March. It is the largest of the 6,600 cryptocurrencies tracked by CoinGecko and makes up more than 50% of the entire $2 trillion market cap of cryptocurrency.

      Historically, the study claims that from January 1, 2016, through June 10, 2018, up to 13 million metric tons of carbon dioxide emissions were generated from bitcoin mining alone. As of April 2020, China alone accounted for 78.89% of the global blockchain operations. Should this trend continue, the emission output would exceed the total annual greenhouse gas emission output of Qatar and the Czech Republic.

      With cheap electricity rates in the country and companies growing more benign towards cryptocurrency, Bitcoin mining is predicted to become even more ubiquitous in the near future. A study by the Cambridge Centre for Alternative Finance from August last year suggested that Bitcoin-related power consumption reached a record high last year with the equivalent of seven nuclear power plants (or 21.8 million solar panels) being pulled by the global mining industry alone.

      Moving forward, the study suggests that imposing carbon taxes alone is not enough to mitigate carbon emissions. Instead, the Chinese government should focus on shifting the industry to renewable sources of energy.

      Nokia base stations to see huge power consumption reduction
      by Paul Hill



      Nokia has announced that it plans to halve its 5G base station power consumption over the next two years. The firm will aim towards these emission reductions by making “continuous improvements” to the software that controls the base stations and by developing new AirScale 5G mMIMO Base Station variants that use the latest SoCs which are more power-efficient.

      Commenting on the work to reduce the emissions of its base stations, Ari Kynäslahti, Head of Technology and Strategy at Nokia Mobile Networks, said:

      In its announcement, Nokia recognised that 5G is set to dramatically increase network traffic, therefore, it wants to implements techniques such as advanced sleep mode and other power-saving features to cut the energy usage.

      By reducing base station emissions, Nokia will be able to more easily work towards its wider goal of halving its 2019 emission by 2030, which it announced at the start of the month. It said that it is working towards new, more ambitious Science Based Targets (SBTs) that will bring it in line to meet the 1.5°C global warming scenario rather than the 2.0°C scenario.

      Nokia to halve its 2019 emissions by the decade's end
      by Paul Hill



      Nokia has today announced that it will reduce its emissions by 50% from its operations and products in use by the end of the decade compared to 2019. The Finnish firm has called its ambitions Science Based Targets (SBTs) and says they’re in line to meet a 1.5°C global warming scenario.

      The firm said that it created SBTs back in 2017 which would bring it in line with a 2.0°C global warming scenario but managed to reach 90% of its targets within its operations 11 years ahead of time so now it’s going for a more ambitious goal. The new targets will apply to almost 100% of the firm’s current portfolio and include emissions from logistics and assembly factories in its supply chain as well as from its own operations.

      Commenting on the news, Nokia’s President and CEO Pekka Lundmark said:

      Nokia is not alone in its efforts to drive down its emissions. Other tech firms including IBM, Amazon, Microsoft and Uber are part of The Climate Pledge which calls on signatories to reach net-zero carbon emissions by 2040 ahead of the Paris Agreement deadline. Under the Paris Agreement, nations and the private sector have to bring down their emissions so much than global warming can be limited to 1.5°C by 2100.

      KaiOS teams up with Justdiggit to connect rural communities
      by Paul Hill



      KaiOS Technologies, the firm behind KaiOS, has announced a new partnership with Justdiggit, a Dutch-based foundation concerned with restoring degraded ecosystems. The two firms will supply 300 rural farmers in Tanzania with KaiOS smart feature phones to get information to them that will improve their livelihoods and help them to regreen their farms to fight desertification.

      Each of the devices come pre-loaded with a new Regreen App that has been developed by KaiOS. The content in the application is sourced from Justdiggit which advocates proven and scalable regreening techniques that have already been used on 60,000 hectares of farmland in Africa in three years.

      According to KaiOS, the threat of desertification and droughts in Africa is huge. It said that 350 million smallholder farmers already deal with these problems or are expected to in the coming years and they can lead to a range of problems including failed harvests and poverty which subsequently creates climate refugees who move to different parts of the world looking for a new way to get by.

      KaiOS phones are designed to be affordable and bridge the gap between feature phones and smartphones. While they typically use a feature phone design, they are equipped with apps such as WhatsApp, Google Maps, YouTube and Facebook. Bringing these devices to the 300 participants, not only helps them better manage their farms but also helps to close the digital divide.

      As an additional benefit to recipients, KaiOS devices come equipped with the Life app which can help provide users with health advice, financial education, digital skills and more.

      After using the devices for several weeks, KaiOS was keen to find out from participants whether they would pay for a device with 52% saying they would spend between $22-28. The firm said that devices with KaiOS already exist in the price range and that it’s a positive sign for the scalability and sustainability of this initiative.

      KaiOS is going to work with other partners in the future to scale up this initiative so that it can get devices into the hands of farmers across the African continent.
