Eight Signs That The Consensus Is We're Headed Toward A Climate Catastrophe
8. Scientists Conclude That Climate Changes is Causing Droughts
The majority of scientists have concluded that climate change is causing life-threatening droughts across the globe. The word bank report on climate change (pdf) offers the consensus scientific view. We’re already topping Dust Bowl temperatures. For example, the Amazonian mega-drought has been linked to climate change and observations from ground stations in the southern Amazon have found that average rainfall in the region dropped nearly 3.2 percent per year in the period from 1970 to 1998.
7. Global Warming Predictions Made by Scientists in 1990 Were Accurate
This is an important finding because it shows that scientists do know what they’re talking about inspite of contradictory industry spin and a willing media that constantly disputes scientific claims. Scientists accurately predicted what the average temperature would be today back in 1990 and they also accurately predicted that global warming was caused by humans and not the result of natural variation. In case you’re still a skeptic, these charts should convince any reasonable person. The above video makes many of the same points or if you prefer images, click here.
6. Scientists Are Beginning To Conclude That Humanity is Doomed
Scientists and in particular scientific organizations are typically cautious and conservative in their statements but that’s no longer the case when it comes to climate science. The fall meeting of the American Geophysical Union was practically apocalyptic as researchers observe that carbon emissions continue to rise worldwide in the face of overwhelming evidence of climate change. Scientists have also concluded that we’ve moved outside the planetary boundaries in other areas as well including extinction rates and the nitrogen cycle.
When the premier journal Nature asks it’s members to risk their careers by speaking out, you know scientists are beginning to feel desperate. Given the political realities some scientists are suggesting it’s too late already.
This year another group of 22 internationally known scientists that are part of the The Berkeley Initiative in Global Change Biology concluded that a combination of climate change, population growth and, widespread destruction of natural ecosystems indicates the Earth is rapidly approaching an irreversible tipping point for humanity. The problem is they’re not sure they will know when will know when the tipping point reached until after it’s too late to do anything about it.
5. A Record Setting Year
The lowest recorded sea-ice, the lowest recorded snow cover extent and duration, and the most extensive recorded melting event on the surface of the Greenland ice sheet all occurred in 2012,
It’s not just scientists that are sounding an alarm. Al Gore has asked President Obama to make climate change his top priority in directing some very tough language at a fellow Democrats. Green Peace issued an open letter to the President that was similarly blunt. Al Gore believes that humanity may have only ninety years left unless something is done now to stop the trend. The World Bank report notes that economists and business experts are not behind the curve in this regard. Activist Naomi Klein said it’s really the only issue that should sway your vote. Some reporters also believe that climate change hell may be inevitable.
3. New Studies Are Conclusive
For the first time, scientists have concluded that ice sheet loss has occurred on both poles over the past twenty years as a result of man made global warming. This year scientists also concluded that humans have caused dramatic tropospheric and stratospheric temperature changes. A new US climate change report by the U.S. Geological Survey, the National Wildlife Federation and Arizona State University in Tempe found evidence of fish, plant and animal population declines and increased extinction risks, cascading effects through ecosystems that are causing dramatic changes in geographical fauna and floral throughout the U.S. In addition, the timing of flowering, laying eggs or migrating has changed throwing ecosystems into chaos. This is lowering the quality of drinking water, increasing pest control problems, reducing crop yields, and increasing erosion.
New studies suggest that planet is heating up faster than expected and in ways that are difficult to counteract. For example, a new report suggests that 100 million will die in the next twenty years as a result of climate change. Damages to agriculture and fisheries could cost $500 billion on year by 2030. This year the report estimated the world economy lost $1.2 trillion dollars (1.6% of the world economy) from climate change and that number will double every ten years. These costs are much larger than the cost of converting to green energy. The full report can be found here (pdf). This report also suggests that climate change is caused 5 million deaths this year – 400,000 due to hunger and communicable diseases aggravated by climate change and 4.5 million carbon economy deaths due mainly to air pollution. The report concludes
“One degree Celsius rise in temperature is associated with 10% productivity loss in farming. For us, it means losing about four million metric tonnes of food grain, amounting to about US$ 2.5 billion. That is about 2% of our GDP. Adding up the damages to property and other losses, we are faced with a total loss of about 3-4% of GDP. Without these losses, we could have easily secured much higher growth.”
Scientists also have supported the conclusions of the dire World Bank Report that projects historic heat waves, droughts, disease, famine, climate refugees and floods by 2060.
2. Third Draft of U.S. Climate Assessment Envisions Hard Times For the US
The report written by 240 scientists suggests that climate change will hit the U.S. hard with flood causing and erosive rains in the Northeast, Midwest and Plains, sea level increases that will destroy coastal communities and widespread fire producing and crop destroying droughts in the West. The report concludes that this isn’t a future scenario but the current situation and it states that it is being caused by humans.
1. Ocean Acidification
A study of New Greenland ice showed that the ice since the beginning of the industrial revolution has been influenced the acidity of the ice. The acidity is so bad it’s dissolving sea snails and shells and coral that constitute a substantial part of humanity’s food supply. The effect is caused by 17 million tons of human produced CO2 being absorbed by the sea each day. This isn’t a future problem. It’s occurring right now.
