  1. A POINT OF NO RETURN? ? ??? Is the earth headed for a point of no return? Some scientists feel that the effect of changes can be difficult to predict. Because of this, they are concerned that we might be approaching “tipping points” where sudden and unanticipated climate changes could bring disastrous results. A polar bear on a small mound of ice Consider, for example, the West Antarctic Ice Sheet. Some believe that with sustained global warming, there is a point where the melt of this ice sheet could be irreversible. This is because ice cover naturally reflects the sunÂ’s rays. But as the ice sheet thins and shrinks, the ocean below, which is less reflective, is eventually exposed. The dark ocean surface absorbs more heat, which in turn leads to greater melting. A self-feeding, runaway cycle could be created. The resulting rise in sea levels from the meltwater could spell disaster for hundreds of millions of people. Regarding the remarkable changes the Kingdom will bring, God declares: “Look! I am making all things new.” (Revelation 21:5) Does this mean that God will replace the earth with a new one? No, for there is really nothing inherently wrong with our planet. Rather, God will do away with those responsible for the planetary crisis, “those ruining the earth,” that is, the present-day human system with its governmental structure. This will be replaced by “a new heaven and a new earth”—a new heavenly government, GodÂ’s Kingdom, ruling over a new earthly society.—Revelation 21:1. To eliminate the ecological debt caused by man, God will rebalance the ecological budget, so to speak. Describing what God will do, the psalmist was inspired to write: “You care for the earth, making it abundantly fruitful and very rich.” With a regulated climate and, above all, GodÂ’s blessing, the earth will become a paradise yielding plenty of food.—Psalm 65:9-13. The creation account in Genesis concludes with the words: “God saw everything he had made, and look! it was very good.” (Genesis 1:31) Truly, the earth is far too precious to end up in environmental bankruptcy. We are comforted in knowing that our planetÂ’s future rests safely in the hands of our loving Creator, Jehovah God. He promises: “The righteous will possess the earth, and they will live forever on it.” (Psalm 37:29) May you be counted among “the righteous,” who will call earth their eternal home.
      Hello guest!
    #Repost @paulnicklen ??? This week I posted a video of a starving bear. It was difficult to film, and even harder to watch, as evidenced by the reactions it elicited. The truth is hard, but photojournalism is more than pretty pictures. It can be a difficult job. Journalism exposes—raw and without bias—the world’s issues in the interest of transparency, honesty and, I believe, change for the better. At @Sea_Legacy, we want to break down the walls of apathy and move people to change. We went to the Canadian Arctic to document the effects of climate change. We found the good, the bad and the ugly, but mostly just beautiful animals and landscapes we want to protect. We will continue to share it all with you in the interest of creating positive and lasting change. Thank you for helping us in #TurningTheTide. @Sea_Legacy with @CristinaMittermeier.

  2. Ice in the Arctic Ocean’s Chukchi Sea region. “What’s going on in the Arctic is really very impressive; this year was ridiculously off the chart,” said Gavin A. Schmidt, the head of NASA’s Goddard Institute for Space Studies. CreditEsther Horvath Marking another milestone for a changing planet, scientists reported on Wednesday that the Earth reached its highest temperature on record in 2016, trouncing a record set only a year earlier, which beat one set in 2014. It is the first time in the modern era of global warming data that temperatures have blown past the previous record three years in a row. The findings come two days before the inauguration of an American president who has called global warming a Chinese plot and vowed to roll back his predecessor’s efforts to cut emissions of heat-trapping gases. In reality, the Earth is heating up, a point long beyond serious scientific dispute, but one becoming more evident as the records keep falling. Temperatures are heading toward levels that many experts believe will pose a profound threat to both the natural world and to human civilization. In 2015 and 2016, the planetary warming was intensified by the weather pattern known as El Niño, in which the Pacific Ocean released a huge burst of energy and water vapor into the atmosphere. But the bigger factor in setting the records was the long-term trend of rising temperatures, which scientists say is being driven by increasing levels of carbon dioxide and other greenhouse gases.

  3. Global warming is said to be bringing temperatures last seen during an interglacial era, when sea level was 6-9 meters (20-30ft) higher than today A coal-fired power station. ‘Massive CO2 extraction’ costing trillions is needed in order to avoid runaway temperature rises, says a new paper. Photograph: Florian Gaertner/Photothek via Getty Images The global temperature has increased to a level not seen for 115,000 years, requiring daunting technological advances that will cost the coming generations hundreds of trillions of dollars, according to the scientist widely credited with bringing climate change to the public’s attention. A new paper submitted by James Hansen, a former senior Nasa climate scientist, and 11 other experts states that the 2016 temperature is likely to be 1.25C above pre-industrial times, following a warming trend where the world has heated up at a rate of 0.18C per decade over the past 45 years. This rate of warming is bringing Earth in line with temperatures last seen in the Eemian period, an interglacial era ending 115,000 years ago when there was much less ice and the sea level was 6-9 meters (20-30ft) higher than today. In order to meet targets set at last year’s Paris climate accord to avoid runaway climate change, “massive CO2 extraction” costing an eye-watering $104tn to $570tn will be required over the coming century with “large risks and uncertain feasibility” as to its success, the paper states. “There’s a misconception that we’ve begun to address the climate problem,” said Hansen, who brought climate change into the public arena through his testimony to the US congress in the 1980s. “This misapprehension is based on the Paris climate deal where governments clapped themselves on the back but when you look at the science it doesn’t compute, it’s not true. “Even with optimistic assumptions (future emissions reduction) will cost hundreds of trillions of dollars. It’s potentially putting young people in charge of a situation that is beyond their control. It’s not clear they will be able to take such actions.” The paper, submitted as a discussion paper to the Earth System Dynamics journal, is a departure from the usual scientific process as it has yet to be peer reviewed and has been launched to support a legal case waged by a group of young people against the US government. Last year, 21 youths aged between 8 and 19 years old filed a constitutional lawsuit against the Obama administration for failing to do enough to slow climate change. Hansen and his granddaughter are parties to legal challenge, which was filed in Oregon and asserts that the government has violated young people’s rights to life, liberty and property. Hansen, who has become increasingly outspoken on climate change since retiring from Nasa in 2013, said he recognized some scientists might object to publicizing the paper so soon but that “we are running out of time on this climate issue.” The courts need to step in to force governments to act on climate change because they are largely free of the corrupting influence of special interests, Hansen said. He repeated his call for a global tax to be placed upon carbon emissions and said that fossil fuel companies should be forced to pay for emissions extraction in the same way the tobacco industry has been sued over the health impact of cigarettes. “The science is crystal clear, we have to phase out emissions over the next few decades,” Hansen said. “That won’t happen without substantial actions by Congress and the executive branch and that’s not happening so we need the courts to apply pressure, as they did with civil rights.” Several recent studies have cast doubt over whether the world will stay with an aspirational target set in Paris of a 1.5C limit on the average global temperature rise. This guardrail, and even the 2C limit agreed by 195 nations, appears dependent on as-yet undeveloped technology that would remove greenhouse gases from the atmosphere. Under this scenario, huge emissions cuts would be supplemented by a widespread conversion to biofuels that would be burned for energy. The emissions from this energy would then be buried underground. Some sort of futuristic technology that sucks CO2 directly from the atmosphere may also be required. Hansen said this is a “dubious” proposition because it requires a vast change in land use at a time where a growing global population will require more food. There are also major doubts whether technology to capture CO2 and lock it underground, often touted as a panacea by the fossil fuel industry, will be developed in time to help avoid the dangerous sea level rise, drought, heatwaves and disease spurred by warming temperatures. Last week, the National Oceanic and Atmospheric Administration said that carbon dioxide levels will not drop below the symbolic 400 parts per million (ppm) mark in our lifetimes – the highest concentration of CO2 since the Pliocene era 3m years ago. The environment of this time, where sea levels were around 65ft higher than today and trees were able to grow near the north pole due to a lack of ice, is a “bellwether for what future climate might be like,” according to Bruce Bauer, a scientist with NOAA’s National Centers for Environmental Information. Michael Mann, a prominent climatologist at Penn State University, agreed that CO2 removal will be required if the world was to avoid 1.5C warming although the 2C limit “could likely be achieved without negative emissions, but it would require urgent action, as I have argued myself is necessary.”. Mann added that Hansen’s paper is “interesting” but tackles a huge range of topics and is unconventional in its use as a tool to support a legal case. “Along with the paper being publicized prior to peer review, this will certainly raise eyebrows about whether or not this breaches the firewall many feel should exist wherein policy agenda should not influence the way that science is done,” Mann told the Guardian via email.
