The biggest alpine lake in North America is warming faster than ever thanks in large part to a changing global climate.

That’s according to scientists who study Lake Tahoe to produce reports on everything from water temperature to clarity to invasive species.

The latest data in the State of the Lake report shows average water temperature in the lake increased nearly half a degree in one year.

Of all the elements that make up Earth’s atmosphere, nitrogen is by far the most abundant. It is also one of the most inert. Nothing happens when you breathe it in, swallow it, or let it suffuse your skin.

Texas probably will see a sharp increase in heat-related deaths and coastal storm-related losses in the coming decades if nothing is done to mitigate a changing climate, according to a new study commissioned by a bipartisan group of prominent policymakers and company executives aiming to spawn concern – and action – in the business community over the much-debated warming trend.

Disastrous Sea Level Rise Is an Issue for Today's Public - Not Next Millennium's

             

huffingtonpost.com - by Dr. James Hansen - July 27, 2015

. . . 2°C global warming, rather than being a safe "guardrail," is highly dangerous. . . .

. . . My conclusion, based on the total information available, is that continued high emissions would result in multi-meter sea level rise this century and lock in continued ice sheet disintegration such that building cities or rebuilding cities on coast lines would become foolish. . . .

. . . A startling conclusion of our paper is that effects of freshwater release onto the Southern Ocean and North Atlantic are already underway and 1-2 decades sooner in the real world than in the model (Fig. 2).

Flood and Drought Risk to Cities on Rise Even with No Climate Change

CLICK HERE - STUDY - Changing global patterns of urban exposure to flood and drought hazards

Summary:  A heads-up to New York, Baltimore, Houston and Miami: a new study suggests that these metropolitan areas and others will increase their exposure to floods even in the absence of climate change.  Their work is published in Global Environmental Change. . . .

. . . "Through land change, bank protection, channelization, and other means, urbanization can also alter the geomorphology of river channels and floodplains, which in turn may contribute to increased risk of flooding."

"Our findings suggest that future urban expansion in flood and drought prone zones will at least be as important as population growth and economic development in increasing their exposure," the researchers add.

"With climatic changes, this exposure is only expected to increase in the future. Thus, proper planning and financing in fast growing cities today will be critical in mitigating future losses due to floods and droughts."

Obama to Seek 40 Percent Cut in Federal Greenhouse Gases

thehill.com - by Timothy Cama - March 19, 2015

President Obama signed an executive order Thursday to cut the federal government’s greenhouse gas emissions 40 percent over the next decade.

The effort will save taxpayers as much as $18 billion due to energy savings, the White House said. . .

. . . Obama will also push federal agencies to get 30 percent of their power from renewable sources like wind and solar energy.

Interaction of Atlantic and Pacific Oscillations Caused 'False Pause' in Warming

sciencedaily.com - February 26, 2015

The recent slowdown in climate warming is due, at least in part, to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate system. They do not signal any slowdown in human-caused global warming.

Obama Vetoes Keystone XL Pipeline, Leaving it in Limbo

reuters.com - By Jeff Mason and Timothy Gardner - February 24, 2015

(Reuters) - President Barack Obama on Tuesday, as promised, swiftly vetoed a Republican bill approving the Keystone XL oil pipeline, leaving the long-debated project in limbo for another indefinite period.

The U.S. Senate Majority Leader Mitch McConnell, after receiving Obama's veto message, immediately countered by announcing the Republican-led chamber would attempt to override it by March 3.

That is unlikely. Despite their majority, Republicans are four votes short of being able to overturn Obama's veto.

They have vowed to attach language approving the pipeline to a spending bill or other legislation later in the year that the president would find difficult to veto.

theguardian.com - February 12 2015 - Suzanne Goldenberg

The US south-west and the Great Plains will face decade-long droughts far worse than any experienced over the last 1,000 years because of climate change, researchers said on Thursday.

The coming drought age – caused by higher temperatures under climate change – will make it nearly impossible to carry on with current life-as-normal conditions across a vast swathe of the country.

White House Moves to Rein In Methane Emissions

       

New EPA standards will aim to significantly cut methane emissions from oil and gas sites in the U.S.

The Obama administration makes its latest move to take on climate change.

usnews.com - by Alan Neuhauser - January 14, 2015

In the Obama administration’s latest use of executive authority to address climate change, the White House announced plans Wednesday to impose new regulations on the oil and gas industry that would nearly halve methane emissions from wells, drill sites and pipelines in 10 years.

The new standards, to be developed by the Environmental Protection Agency under the Clean Air Act, would aim by 2025 to cut methane emissions by up to 45 percent from levels recorded in 2012. They would also slash the spread of volatile organic compounds, or VOCs, key components of ground-level smog that have been linked to cancer, neurological conditions and other illnesses.
