Globally, this was the second warmest March in the 140-year record, with a temperature departure from average at +1.06°C (+1.91°F). Only March 2016 was warmer at +1.24°C (+2.23°F). March 2019 also marks the third time (2016, 2017, and 2019) that the March global land and ocean surface temperature departure from average surpasses 1.0°C (1.8°F). The March 2019 global land and ocean temperature tied with January 2016 as the fifth highest monthly temperature departure from average for any month on record (1671 months). The 20 highest monthly temperature departures from average have all occurred since 2015, with March 2016 having the highest monthly temperature departure in the 1671-month record at +1.24°C (+2.23°F).That's what the science says.
And if you wanted another reason as to why this is occurring (or better, "being allowed to occur") then take a look at this study just published by the National Academy of Sciences:
We find that global warming has very likely exacerbated global economic inequality, including ∼25% increase in population-weighted between-country inequality over the past half century. This increase results from the impact of warming on annual economic growth, which over the course of decades has accumulated robust and substantial declines in economic output in hotter, poorer countries—and increases in many cooler, wealthier countries—relative to a world without anthropogenic warming. Thus, the global warming caused by fossil fuel use has likely exacerbated the economic inequality associated with historical disparities in energy consumption. Our results suggest that low-carbon energy sources have the potential to provide a substantial secondary development benefit, in addition to the primary benefits of increased energy access.So when the soft-core climate science denialists assert that the solution to climate change is a global redistribution of wealth (downward, from rich to poor), just remember that they're actually protecting a redistribution system that's already in place - one that's shifting money upward from poor to rich.
