Yesterday the Obama administration released the third U.S. National Climate Assessment in Washington and welcomed national meteorologists and scientists to the White House in an effort to help understand the key reasons behind climate change as Americans struggle to cope with severe weather that plagues the country.
The assessment is the culmination of a three year study by a team of over 300 climate scientists and experts.
Many Americans led by conservative Republican groups have been highly suspicious of climate research that is used to show that climate change is man-made and insist that its unfair to blame humans for natural changes to the climate.
According to research from Pew Research, Americans are relatively unconcerned about global climate change when measured against citizens from other nations.
Only four-in-ten surveyed Americans said that climate change poses a major threat to their nation which ranks among the bottom of the list compared to citizens from other countries.
Energy Secretary Ernest Moniz issued a statement during the release of the U.S. National Climate Assessment.
“The scientific community has been sounding the alarm over climate change for decades, and the 3rd U.S. National Climate Assessment released today offers the most comprehensive scientific report to date on U.S. climate change impacts” Moniz said.
“If our emissions of greenhouse gases remain unabated, we will face increasingly significant damages, including rising sea levels and an increase in droughts, heat waves, wildfires and intense storms” Moniz added later.
The findings from the U.S. National Climate Assessment revealed that the global warming of the past 50 years is primarily due to human activities.
The research findings from the U.S. National Climate Assessment revealed that the earth is getting warmer as “many more high temperature records are being broken as compared to low temperature records over the past three to four decades – another indicator of a warming climate.”
“The number of record low monthly temperatures has declined to the lowest levels since 1911, while the number of record high monthly temperatures has increased to the highest level since the 1930s” according to the assessment.
A new record for minimum area of Arctic sea ice was established in 2012.
The assessment claims that the majority of the warming to the earth during the past 50 years can only be explained by the effects of human influences, such as the emissions from burning fossil fuels (coal, oil, and natural gas) and from deforestation.
