Tracking the movement of the tropics 800 years into the past

Tracking the movement of the tropics 800 years into the past

For the first time, scientists have traced the north-south shifts of the northern-most edge of the tropics back 800 years. The movement of the tropical boundary affects the locations of Northern Hemisphere deserts including the Sonoran, Mohave and Saharan. The Earth's climate system affects the movement of the tropics, which have been expanding since the 1970s. The research team found that in the past, periods of tropical expansion coincided with severe droughts.

“Earth is Morphing into Venus” - Late Stephen Hawking

Stephen Hawking’s Pre-UN Report: “Wake Up, Science Deniers! –“Earth is Morphing into Venus”


Data gathered from European Space Agency’s Venus Express is invaluable to climate scientists modeling Earth’s climate to predict its future.Astrobiologist David Grinspoon believes that scientists should look at our neighboring planets to help understand the perils of global warming.“It seems that both Mars and Venus started out much more like Earth and then changed. They both hold priceless climate information for Earth.”

Climate scientists believe that Venus experienced a runaway greenhouse effect as the Sun gradually heated up. Astronomers believe that the young Sun was dimmer than the present-day Sun by 30 percent. Over the last 4 thousand million years, it has gradually brightened. During this increase, Venus’s surface water evaporated and entered the atmosphere.

“Water vapor is a powerful greenhouse gas and it caused the planet to heat-up even more. This is turn caused more water to evaporate and led to a powerful positive feedback response known as the runaway greenhouse effect,” says Grinspoon.

Climate report: Scientists politely urge, 'act now, idiots'



Climate report: Scientists politely urge, 'act now, idiots'

Their dramatic report on keeping that rise under 1.5 degrees C states that the world is now completely off track, heading instead towards 3C.

Staying below 1.5C will require "rapid, far-reaching and unprecedented changes in all aspects of society".

It will be hugely expensive, the report says, but the window of opportunity is not yet closed.

After three years of research and a week of haggling between scientists and government officials at a meeting in South Korea, the Intergovernmental Panel on Climate Change (IPCC) has issued a special report on the impact of global warming of 1.5C...

What happens if we don't act?

The researchers say that if we fail to keep temperatures below 1.5C, we are in for some significant and dangerous changes to our world.

You can kiss coral reefs good-bye, as the report says they would be essentially 100% wiped out at 2 degrees of warming.

Global sea-level will rise around 10 centimetres more if we let warming go to 2C, That may not sound like much but keeping to 1.5C means that 10 million fewer people would be exposed to the risks of flooding.

There are also significant impacts on ocean temperatures and acidity, and the ability to grow crops like rice, maize and wheat.

"We are already in the danger zone at one degree of warming," said Kaisa Kosonen from Greenpeace.

"Both poles are melting at an accelerated rate; ancient trees that have been there for hundreds of years are suddenly dying; and the summer we've just experienced - basically, the whole world was on fire."   -  FULL ARTICLE HERE.

IPCC Special Report on 1.5ºC

Responding to climate change is far more like a marathon than a sprint.

The IPCC 1.5ºC Special report (#SR15) has been released:

Deadly heat waves to hit India, Pakistan every year because of climate change – UN report

A heat wave like the one in 2015 in India which killed nearly 2,500 people may become an annual occurrence in India and Pakistan, a damning UN report on the threats of climate change claims.

According to the report published on Monday, if world temperatures do indeed rise by two degrees Celsius, India could see deadly heat waves increase in frequency and become an annual condition.

The much-anticipated ‘1.5 Health Report’ was released on Monday in South Korea by the Intergovernmental Panel on Climate Change (IPCC), a UN body set up in 1988, and written by 91 authors from 40 different countries.

Global Warming and the Great Barrier Reef Australia

Coral bleaching is currently one of the biggest threats to the great barrier reef, with damage recorded over hundreds of square kilometres. However, the best way to understand why, and how, is to take a scientific perspective. With the hallmarks of scientific writing, being about the causal relationship of the problem, and clearly identifying it, references to other trusted scientific articles, making predictions about the future effects, and identifying other complicating factors. This is not an article about climate change, rather about the current changing climate of the reef, and how it is being effected.

CAPE TOWN: An Omen of How Climate Will Affect Politics.

How Will Climate Affect Politics?
Climate change is going to revolutionize politics in cities across the world.


The popular use of the phrase “Day Zero” likely began in early 2017, when it became clear that the worst drought in the region’s recorded history wasn’t going anywhere soon. In May, premier of the Western Cape and former Cape Town mayor Helen Zille declared the province, in which Cape Town is located, a disaster area, speeding up the implementation of the province’s “Avoiding Day Zero” plan. Local dam levels around that time dipped to one-fifth of their total capacity. Heading into summer, the situation became more dire and the political messaging grew more urgent. “If consumption is not reduced to the required levels of 500 million liters of collective use per day, we are looking at about March 2018 when supply of municipal water would not be available,” Cape Town Mayor Patricia de Lille told her constituents in October....

as Armitage told me, the water-saving strategies and social-engineering plans embraced by local politicians didn’t make many friends on the ground in the city. Almost immediately after city leaders announced the first Day Zero predictions, they came under heavy scrutiny from citizens and activists, especially among Cape Town’s communities of color. Many in labor, socialist, and leftist organizations in the region didn’t believe Day Zero was even a thing. Elements from those organizations created the Cape Town Water Crisis Coalition, which protested Day Zero as propaganda designed both to cover up faulty city water management and to deny expanded access to low-income communities.

“The purpose of all this (mis)information is clear: shifting blame from government,” reads an op-ed posted to the Water Crisis Coalition website shortly after the 50-liter household limit was passed by the local government. The Coalition asserted that “in fact, all tiers of Government is complicit through lack of foresight and mismanagement of our water resources.” Through a series of intense protests and heated confrontations with officials in the summer, members of the group stressed that a mobilization of citizens on the order of the old anti-apartheid movement would be required to create the political change necessary to secure the water future of the Western Cape and South Africa. A common refrain in their rallies, marches, and street arguments with Democratic Alliance politicians, the Coalition’s slogan is “water for all or the city must fall.”

Irony Will Take Us To Our Grave

Discussion 101Collapse )

NHTSA study forecasts dangerous rise in world temperatures by 2100

But it's being used to justify relaxing environmental standards

The Trump administration has accepted the scientific consensus of human-made global warming. However, it's not being used to push for tougher environmental regulations — just the opposite, in fact. In a draft NHTSA environmental impact statement for Trump's proposed fuel standards freeze, the agency predicts that the worldwide temperature will increase about 7 degrees Fahrenheit (4 Celsius) over pre-industrial levels by 2100. Rather than use that as an incentive to push for more drastic cuts in emissions, though, the report claims that there's not much point. It's allegedly "not currently technologically feasible or economically feasible" to move enough people to clean transportation to make a difference, the NHTSA argued, so why bother with tougher rules?

The problem, as MIT professor John Sterman told the Washington Post, is that the administration is cherry-picking statistics to make action appear ineffective. It mainly compares its own weakened policies to the "No Action" approach, making the difference seem smaller than it would be if it was compared to Obama-era emissions cuts. The administration's own studies suggest that even the car rule would pump 8 billion tons of CO2 into the atmosphere if companies don't improve emissions on their own. We'd add that it's a fatalist stance. Even if more substantial cuts didn't do much, they would do something — even if it's short-term improvements like reduced air pollution.

And while 7F doesn't sound like much, it could lead to dire consequences. Global warming is already melting glaciers and killing coral reefs, and that's only likely to get worse if temperatures keep rising. The study accepted that droughts, flooding and other natural disasters were already happening as a result of global warming.

If there's any consolation, it's that automakers won't necessarily abuse the looser rules. Most major brands are planning much larger selections of electric and hybrid cars in the next several years. Moreover, car ownership might decline as more people decide to use car sharing services and shared self-driving transportation. It's just that these reductions in car-related emissions could come in spite of the current government, not because of it.
