PPT-Climate change in the Arctic is thawing permafrost soils and changing vegetation, altering

Water samples collected over six years from major Arctic rivers wwwarcticgreatriversorg were analyzed using the MagLabs recordsetting 21T ultrahighresolution Fouriertransform ion cyclotron resonance mass spectrometer This magnet systems resolving power is capable of determining elemental composition for tens of thousands of individual molecules in a single water sample Combined with isotopic data these formulae revealed both a common core amongst samples as well as unique tracers of seasonality and a changing Arctic .

Global climate is changing rapidly compared to the pace of natural variations in climate that have occurred throughout Earth’s history. Global average temperature has increased by about 1.8°F from 1901 to 2017, and observational evidence does not support any credible natural explanations for this amount of warming; instead, the evidence consistently points to human activities, especially emissions of greenhouse or heat-trapping gases, as the dominant cause..
