US Scientist warn of dire consequences of Climate Change

[Aba Incieni]

You can either choose to live in a closet or in the real world. In the real world, we must not ignore what are ominous signs of things to come.

They all chose to live in an echo chamber.

You just echoed what he said, Baldy.

Changes in Severe Storms


Human-induced change is affecting atmospheric dynamics and contributing to the poleward expansion of the tropics and the northward shift in Northern Hemisphere winter storm tracks since 1950. Increases in greenhouse gases and decreases in air pollution have contributed to increases in Atlantic hurricane activity since 1970. In the future, Atlantic and eastern North Pacific hurricane rainfall and intensity are projected to increase, as are the frequency and severity of landfalling “atmospheric rivers” on the West Coast.

Nothing real at all here, the al gore pump is still making money for the next dimshit campaign maybe they will beat the oshit reelection theft with solindra and the rest.

Long-Term Changes


The climate change resulting from human-caused emissions of carbon dioxide will persist for decades to millennia. Self-reinforcing cycles within the climate system have the potential to accelerate human-induced change and even shift Earth’s climate system into new states that are very different from those experienced in the recent past. Future changes outside the range projected by climate models cannot be ruled out, and due to their systematic tendency to underestimate temperature change during past warm periods, models may be more likely to underestimate than to overestimate long-term future change.

………….

Humanity’s effect on Earth’s climate system since the start of the industrial era, through the large-scale combustion of fossil fuels, widespread deforestation, and other activities, is unprecedented. Atmospheric carbon dioxide concentrations are now higher than at any time in the last 3 million years,191 when both global average temperature and sea level were significantly higher than today.24 One possible analog for the rapid pace of change occurring today is the relatively abrupt warming of 9°–14°F (5°–8°C) that occurred during the Paleocene-Eocene Thermal Maximum (PETM), approximately 55–56 million years ago.192 ,193 ,194 ,195 Although there were significant differences in both background conditions and factors affecting climate during the PETM, it is estimated that the rate of maximum sustained carbon release was less than 1.1 gigatons of carbon (GtC) per year (about a tenth of present-day emissions rates). Present-day emissions of nearly 10 GtC per year suggest that there is no analog for this century any time in at least the last 50 million years. Moreover, continued growth in carbon emissions over this century and beyond would lead to atmospheric CO2 concentrations not experienced in tens to hundreds of millions of years55 ,195 (see Hayhoe et al. 201724 for further discussion of paleoclimate analogs for present and near-future conditions).

"US Scientist warn of dire consequences of Climate Change"

But aren't we still waiting for all of the other predictions of "dire consequences"?...like Polar Bear extinction and Island flooding?...last time I checked Hawaii is still there....what it is folks...is its government grant time....its about money and power...its always been about money and power....just like the predicted Ice Age during the 70's...don't buy the bullshit folks....climate changes all the time and there is nothing we can do to stop it and there was nothing we did to change it...

For those that are interested in the science and the report, here is a link to the report.

Fourth National Climate Assessment: Executive Summary

From the report:

Introduction
Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. The impacts of global climate change are already being felt in the United States and are projected to intensify in the future—but the severity of future impacts will depend largely on actions taken to reduce greenhouse gas emissions and to adapt to the changes that will occur. Americans increasingly recognize the risks climate change poses to their everyday lives and livelihoods and are beginning to respond (Figure 1.1). Water managers in the Colorado River Basin have mobilized users to conserve water in response to ongoing drought intensified by higher temperatures, and an extension program in Nebraska is helping ranchers reduce drought and heat risks to their operations. The state of Hawai‘i is developing management options to promote coral reef recovery from widespread bleaching events caused by warmer waters that threaten tourism, fisheries, and coastal protection from wind and waves. To address higher risks of flooding from heavy rainfall, local governments in southern Louisiana are pooling hazard reduction funds, and cities and states in the Northeast are investing in more resilient water, energy, and transportation infrastructure. In Alaska, a tribal health organization is developing adaptation strategies to address physical and mental health challenges driven by climate change and other environmental changes. As Midwestern farmers adopt new management strategies to reduce erosion and nutrient losses caused by heavier rains, forest managers in the Northwest are developing adaptation strategies in response to wildfire increases that affect human health, water resources, timber production, fish and wildlife, and recreation. After extensive hurricane damage fueled in part by a warmer atmosphere and warmer, higher seas, communities in Texas are considering ways to rebuild more resilient infrastructure. In the U.S. Caribbean, governments are developing new frameworks for storm recovery based on lessons learned from the 2017 hurricane season.

Climate-related risks will continue to grow without additional action. Decisions made today determine risk exposure for current and future generations and will either broaden or limit options to reduce the negative consequences of climate change. While Americans are responding in ways that can bolster resilience and improve livelihoods, neither global efforts to mitigate the causes of climate change nor regional efforts to adapt to the impacts currently approach the scales needed to avoid substantial damages to the U.S. economy, environment, and human health and well-being over the coming decades.

So, how come Earth doesn't just evolve to deal with a little wisp of CO2

we can do a couple of things

like the invention of heat in homes when the climate is cold

and the invention of AC when the climate is hot

Increases in Coastal Flooding


Regional changes in sea level rise and coastal flooding are not evenly distributed across the United States; ocean circulation changes, sinking land, and Antarctic ice melt will result in greater-than-average sea level rise for the Northeast and western Gulf of Mexico under lower scenarios and most of the U.S. coastline other than Alaska under higher scenarios. Since the 1960s, sea level rise has already increased the frequency of high tide flooding by a factor of 5 to 10 for several U.S. coastal communities. The frequency, depth, and extent of tidal flooding are expected to continue to increase in the future, as is the more severe flooding associated with coastal storms, such as hurricanes and nor’easters.

Not happening it is just a regular cycle that happens and has nothing to do with your dog crapping in the park or your 1910 huppmobile

Every single item you have spouted has been debunked by empirically observed evidence.. Your pontifications are 100% false and have been shown fraud over and over again..

You use modeling that has NO PREDICATIVE POWER and you want us to believe you...

You guys can live in the denialist bubble for only so long. It is all coming to a head and the people will soon rise to demand action, and not soon enough.

Johnlaw, every one of the undereducated RW nuts on this board are convinced that real scientists are elitists involved in a conspiracy directed by Al Gore, and that only Trump, and his superior in-depth scientific education on climate change and firefighting is right. In short, don't waste your time. You have a better chance teaching physics to your cat.

Whats coming to ahead is the fact that we have maximum cooling at the poles going on and you folks are masking it from the public. You alter the climatic records to further your agenda and with all the creative manipulations the earths cooling is about to kick you idiots in the teeth..

Tell us how we are experiencing maximum thermal cooling (-90 deg C) with your so called GHG's giving the planet a fever? You do realize your scam has been outed and the lie will no longer remain hidden..

Antarctic temperatures recently plunged close to the theoretically coldest achievable on Earth!
